2021 Year in Review: Google Quantum AI
Google’s Quantum AI team has had a productive 2021. Despite ongoing global challenges, we’ve made significant progress in our effort to build a fully error-corrected quantum computer, working towards our next hardware milestone of building an error-corrected quantum bit (qubit) prototype. At the same time, we have continued our commitment to realizing the potential of quantum computers in various applications. That’s why we published results in top journals, collaborated with researchers across academia and industry, and expanded our team to bring on new talent and expertise.
An update on hardware
The Quantum AI team is determined to build an error-corrected quantum computer within the next decade, and to simultaneously use what we learn along the way to deliver helpful—and even transformational—quantum computing applications. This long-term commitment is expanded broadly into three key questions for our quantum hardware:
- Can we demonstrate that quantum computers can outperform the classical supercomputers of today in a specific task? We demonstrated beyond-classical computation in 2019.
- Can we build a prototype of an error-corrected qubit? In order to use quantum computers to their full potential, we will need to realize quantum error correction to overcome the noise that is present during our computations. As a key step in this direction, we aim to realize the primitives of quantum error correction by redundantly encoding quantum information across several physical qubits, demonstrating that such redundancy leads to an improvement over using individual physical qubits. This is our current target.
- Can we build a logical qubit which does not have errors for an arbitrarily long time? Logical qubits encode information redundantly across several physical qubits, and are able to reduce the impact of noise on the overall quantum computation. Putting together a few thousand logical qubits would allow us to realize the full potential of quantum computers for various applications.
Progress toward building an error-corrected qubit prototype
The distance between the noisy quantum computers of today and the fully error-corrected quantum computers of the future is vast. In 2021, we made significant progress in closing this gap by working toward building a prototype logical qubit whose errors are smaller than those of the physical qubits on our chips.
This work requires improvements across the entire quantum computing stack. We have made chips with better qubits, improved the methods that we use to package these chips to better connect them with our control electronics, and developed techniques to calibrate large chips with several dozens of qubits simultaneously.
These improvements culminated in two key results. First, we are now able to reset our qubits with high fidelity, allowing us to reuse qubits in quantum computations. Second, we have realized mid-circuit measurement that allows us to keep track of computation within quantum circuits. Together, the high-fidelity resets and mid-circuit measurements were used in our recent demonstration of exponential suppression of bit and phase flip errors using repetition codes, resulting in 100x suppression of these errors as the size of the code grows from 5 to 21 qubits.
Suppression of logical errors as the number of qubits in the repetition code is increased. As we increase the code size from 5 to 21 qubits, we see 100x reduction in logical. Image acknowledgement: Kevin Satzinger/Google Quantum AI
Repetition codes, an error correction tool, enable us to trade-off between resources (more qubits) and performance (lower error) which will be central in guiding our hardware research and development going forward. This year we showed how error decreases as we increase the number of included qubits for a 1-dimensional code. We are currently running experiments to extend these results to two-dimensional surface codes which will correct errors more comprehensively.
Applications of quantum computation
In addition to building quantum hardware, our team is also looking for clear margins of quantum advantage in real world applications. With our collaborators in academia and industry, we are exploring fields where quantum computers can provide significant speedups, with realistic expectations that error-corrected quantum computers will likely require better than quadratic speedups for meaningful improvements.
As always, our collaborations with academic and industry partners were invaluable in 2021. One notable collaboration with Caltech showed that, under certain conditions, quantum machines can learn about physical systems from exponentially fewer experiments than what is conventionally required. This novel method was validated experimentally using 40 qubits and 1300 quantum operations, demonstrating a substantial quantum advantage even with the noisy quantum processors we have today. This paves the way to more innovation in quantum machine learning and quantum sensing, with potential near-term use cases.
In collaboration with researchers at Columbia University, we combined one of the most powerful techniques for chemical simulation, Quantum Monte Carlo, with quantum computation. This approach surpasses previous methods as a promising quantum approach to ground state many-electron calculations, which are critical in creating new materials and understanding their chemical properties. When we run a component of this technique on a real quantum computer, we are able to double the size of prior calculations without sacrificing accuracy of the measurements, even in the presence of noise on a device with up to 16 qubits. The resilience of this method to noise is an indication of its potential for scalability even on today’s quantum computers.
We continue to study how quantum computers can be used to simulate quantum physical phenomena—as was most recently reflected in our experimental observation of a time crystal on a quantum processor (Ask a Techspert: What exactly is a time crystal?). This was a great moment for theorists, who’ve pondered the possibility of time crystals for nearly a century. In other work, we also explored the emergence of quantum chaotic dynamics by experimentally measuring out-of-time-ordered correlations on one of our quantum computers, which was done jointly with collaborators at the NASA Ames Research Center; and experimentally measuring the entanglement entropy of the ground state of the Toric code Hamiltonian by creating its eigenstates using shallow quantum circuits with collaborators at the Technical University of Munich.
Our collaborators contributed to, and even inspired, some of our most impactful research in 2021. Quantum AI remains committed to discovering and realizing meaningful quantum applications in collaboration with scientists and researchers from across the world in 2022 and beyond as we continue our focus on machine learning, chemistry, and many-body quantum physics.

Continuing investment in the quantum computing ecosystem
This year, at Google’s annual developer conference, Google I/O, we reaffirmed our commitment to the roadmap and investments required to make a useful quantum computer within the decade. While we were busy growing in Santa Barbara, we also continue to support the enablement of researchers in the quantum community through our open source software. Our quantum programming framework, Cirq, continues to improve with contributions from the community. 2021 also saw the release of specialized tools in collaboration with partners in the ecosystem. Two examples of these are:
- The release of a new Fermionic Quantum Simulator for quantum chemistry applications in collaboration with QSimulate, taking advantage of the symmetry in quantum chemistry problems to provide efficient simulations.
- A significant upgrade to qsim which allows for simulation of noisy quantum circuits on high performance processors such as GPUs via Google Cloud, and qsim integration with NVIDIA’s cuQuantum SDK to enable qsim users to make the most of NVIDIA GPUs when developing quantum algorithms and applications.
We also released an open-source tool called stim, which provides a 10000x speedup when simulating error correction circuits.
You can access our portfolio of open-source software here.
Looking toward 2022

Through teamwork, collaboration, and some innovative science, we are excited about the progress that we have seen in 2021. We have big expectations for 2022 as we focus on progressing through our hardware milestones, the discovery of new quantum algorithms, and the realization of quantum applications on the quantum processors of today. To tackle our difficult mission, we are growing our team, building on our existing network of collaborators, and expanding our Santa Barbara campus. Together with the broader quantum community, we are excited to see the progress that quantum computing makes in 2022 and beyond.
Tools to help you tackle your New Year’s resolution
You always hear the standard New Year resolutions: Work out more. Run a marathon. Learn a new language. For me this year, it’s to learn three new party tricks (I’m optimistically hoping for more social interaction in 2022!). No matter what the goal is, it often feels that by February, I’ve lost some steam. Resolutions take time, and new habits and skills are (let’s admit) hard to build.
So this year, my New Year’s resolution is to stick to a New Year’s resolution. So I did a little digging, and found a few tools that I have at my fingertips to get that resolution to stick.
First things first: Write down your goal
Don’t justthink about your resolution — write it down. If you live by your inbox, schedule send a January 1 New Year’s resolution email to yourself. What better way to kickstart the new year than with an email to your future self?
If you’re not into email, Google Keep is a great way to jot down resolution ideas. If you’re on the go when inspiration strikes, you can even create a Google Keep note with your voice.
And don’t forget good ol’ pen and paper. Recording something on paper is easy, and the physical movement of writing something down can make it stick in a certain way. So write it down, literally.
Next, create reminders
The hard part about keeping resolutions for me is changing my daily routine. So I decided to
break down my resolution into smaller goals, and set up check-ins on Google Calendar. Twice a month, I put aside time to learn a party trick (my first one is going to be rolling a coin across my knuckles), and half way through the year I set up a “dry run” performance with friends (whether that ends up being in-person or virtual) to keep myself accountable.
Aside from checkpoints, crossing items off a checklist also keeps me on track. So I further broke down my twice-a-month trick-learning efforts using Tasks. This means my smaller, bite-sized agenda items will show up everywhere, from Gmail to Google Slides (so I can’t ignore them!).
If you wrote down your resolution on Google Keep, that’s also a good place to create a to-do list and hit your smaller target goals on your way to your resolution. You can even set up timed reminders for each of the items to make sure you hit your goals.
Build satisfaction by tracking your progress
You can track your progress anywhere, like Keep or even Google Docs, but if you’re looking for more, try AppSheet . With AppSheet, you can build custom apps without any coding required. Need a custom app to track your workout progress? Looking for a journaling app on the go? AppSheet has a few templates you can try — or you can build your own if you want to get hyper-specific.
Make sure to reward yourself along the way
New habits and skills are hard to build, especially when you don’t see immediate results. So celebrating mini-milestones along the way (practiced 10 sessions ☑…rehearsed for my dry run ☑) help me stay motivated.
How you reward yourself is up to you — maybe it’s taking a day for self care, or simply exchanging words of encouragement with your friends and family – a little kudos goes a long way. And if at any point along the way toward your goal you begin to feel a little weary, try some of the advice from our resilience expert at Google, who talks about breaking tasks into smaller challenges that are easier to tackle.
Here’s to 2022 — and sticking with our New Year resolutions.

Perché la Brexit è una pessima idea, spiegato benissimo in cinque minuti
Di solito non mi occupo di politica. Però mi occupo spesso di stupidità e di bufale, e la Brexit è un esempio su vasta scala delle conseguenze della stupidità e delle bufale, ed è un esempio che come persona nata in UK e con tanti amici e affetti in quel paese mi tocca da vicino.
La persona che parla, Adam Posen, è presidente del Peterson Institute for International Economics, oltre che ex policymaker per la Banca d’Inghilterra. Questa è la sintesi di quello che disse nel 2017 presso l’American Enterprise Institute.
In cinque minuti, con parole chiare e dirette, mette perfettamente a nudo la colossale stupidità di uscire da un accordo commerciale come l’Unione Europea, per ragioni estremamente pratiche e pragmatiche. Darei molto per avere la lucidità e chiarezza di linguaggio di questa persona.
This is the most chilling explanation of what Brexit will do to the UK economy after December.

…it is a negative supply shock in that you are ruining your competitiveness specifically with your largest trading partner. It is a fact of life — it’s one of the few things in economics we can talk about as a fact of life — that “gravity“ applies.
What is gravity? You trade far far more with the countries you are contiguous with and the countries that you historically have interacted with than with countries that are far away. That is true for the US in the context of NAFTA; that is true for the UK. No matter how much there’s been a special relationship, no matter how much the UK tries to be a global exporter, the fact is you’ve got more than twice as much trade with the EU, more than twice as much investment with the EU as you do with the US or let alone the rest of the world. As David Cameron pointed out when Prime Minister while I was at the Bank of England, the UK does more trade with Ireland than they do with the BRIC countries combined: Brazil, Russia, India, and China. So this is negative, full stop.
…Additionally, because the UK had this special status as the less regulated, less — low tax, English-speaking, rule-of-law place (not that all of that was in question elsewhere in the EU, and certainly Ireland was similar) but had this special place, and people liked living in London, you had a huge amount of investment in the UK as a platform to enter the EU, because you were part of the EU deal. That goes away. It may not go to zero, but it will gradually come down. I see a representative for example of Toyota Motor Corporation here. Toyota, Nissan, Ford, all have disproportionate amounts of their European auto production in the UK. All have indicated that they will not expand those productions and will probably decline those production points in the UK when the UK loses full market access.
…There’s a distinction between a trade deal and access to the single market. The single market is covering all those things that aren’t simply the price of goods off the boat. It’s whether your auto meets safety standards. It’s whether your chemicals or your food additives have been recognized. It’s whether you fit standard sizes of various objects. It’s whether your accountants are accredited. It’s whether your university degree is recognized in other countries’ universities.
…the question is, since the UK primarily is an exporter of high-end products and of services, especially financial services, business services, media services, cultural services, educational services, how much do they lose by not being in the single market, even if you have a trade deal? And the answer is, a lot.
Most of the financial regulation that affected the UK was set in the UK and was not set by Brussels, and while the UK was in the EU they had a predominant voice in the setting of those regulations in Brussels. Now there will be no such interest. And that is why we are seeing an estimate of my colleague Simeon Djankov, who runs the financial markets group at the London School of Economics, a third of City jobs — the economic and financial jobs in the City of London — will be moving to Dublin, Frankfurt, New York.
…You can say “Ah, but this is for centuries, over the long term it will be better.” So then you have to think about what’s wrong with the EU economy versus the UK economy. So most of us who see there being problems in the EU economy as a whole (or at least the euro area economy, because frankly Eastern Europe isn’t doing so bad) tend to focus on five things: we say there’s over-regulation of labor markets, there’s heavy-handed regulation of other things, there’s an excessive welfare state, there’s demographic decline, and there’s the problems of being associated with the euro membership.
Now if you look at that list, four of those five do not apply to the UK even as members of the EU. The UK has a looser labor market regulations than anyone else in the EU, the UK has a smaller welfare state than anyone else in the EU, the UK was a beneficiary in the demographic sense of people from Poland and France and Portugal and elsewhere and Romania coming and helping balance out the aging of their society, and the UK was of course not a member of the European monetary system. Even if the UK were to stay in the EU, none of that would change.
So what is it getting? So you’re balancing, essentially, non-financial regulation in certain areas being excessive versus all the other stuff I spoke about. And giving up the ability to affect or push back against those regulations in the future, because you will no longer be a member.
Leave the rhetoric aside. Look at the reality: this is not a very good deal in economic terms.
Now, again, you can always say, “Well, this is about sovereignty, they want to do it”. Again, I’m not fit to say. That’s fine, but you should be aware that there is no economic upside to this.
