Aram Harrow has spent 25 of his 46 years working in quantum computing. He is a researcher at the Massachusetts Institute of Technology (MIT) and is best known for co-developing the HHL algorithm in 2008, considered one of the first demonstrations of an exponential advantage of quantum computers<\/a> over classical ones. This June marks the end of the year he has spent at Spain\u2019s Institute of Mathematical Sciences (ICMAT) in Madrid, where he speaks with EL PA\u00cdS.<\/p>\n

Quantum computing has spent years promising astonishing breakthroughs. But in 2022, ChatGPT arrived, and AI dethroned it as the technology most likely to solve humanity\u2019s biggest problems. Harrow, however, explains that now it finally seems possible that quantum computers and quantum software \u2014 two separate challenges \u2014 may actually begin to deliver results.<\/p>\n

Question. What is the worst prediction you have made in these 25 years?<\/p>\n

Answer. I have been too pessimistic. I always said it would take 10 to 15 years. Now I think we have to be prepared for interesting quantum computers to appear sooner, in the range of thousands of qubits.<\/p>\n

Q. Really?<\/p>\n

A. We already have little quantum computers. The next step is when they can do something useful that is impossible for our current computers. That\u2019s when quantum computing will have arrived.<\/p>\n

Q. Will there be a \u201cquantum day\u201d like the arrival of ChatGPT?<\/p>\n

A. It will be gradual. We already had the day when Google ran its quantum computer<\/a>, and no classical machine could simulate what it did. That day came and went.<\/p>\n

Q. That\u2019s true. There was even a Spaniard on the project. But that milestone passed.<\/p>\n

A. And we keep going.<\/p>\n

Q. Where are we now?<\/p>\n

A. We\u2019ve reached a higher point, but only a little bit higher. Regarding software, one thing we have achieved is better error correction.<\/p>\n

Q. It\u2019s not headline material.<\/p>\n

A. Exactly. One way to view it is like Moore\u2019s Law for classical computers. Every 18 months they would get better. Some people talk about something called Sch\u00f6lkopf\u2019s law, which is similar, and suggests that qubit quality improves every year in quantum computers. What ultimately determines whether we can build a scalable quantum computer is how many operations you can perform on a qubit before noise ruins your data.<\/a><\/p>\n

Q. And does that law work?<\/p>\n

A. It\u2019s steadily improving. Each year the noise rate goes down a bit. There are two axes. On the one hand, the noise rate gets a little bit better each year; on the other, the challenge is integrating more qubits. You need to advance both at the same time.<\/p>\n

Q. Quantum algorithms are ahead of the machines.<\/p>\n

A. When you think of quantum algorithms<\/a>, imagine you\u2019ve been waiting 20 years for a car to be built. While you build roads, parking lots, even car washes, you\u2019re preparing everything and imagining what the car will be like. There are things you can do, and others you only figure out once you have the car.<\/p>\n

Q. That is, the computer.<\/p>\n

A. One field where we\u2019ve just seen that is AI. Some of its algorithms were developed in the 1960s and didn\u2019t work well until they were given all the data they have now. You couldn\u2019t have predicted they would work well. You just had to try them and then you saw it. Something similar happens with quantum computers: there is a lot we know only on paper. We know the chemistry will work. But also, as they start to be built, we\u2019ll learn much more.<\/p>\n

Q. What do you mean by chemistry?<\/p>\n

A. One major application is simulating a molecule for chemistry or materials science problems, and another one is breaking encryption codes<\/a>. Both could happen sooner than expected.<\/p>\n

Q. Molecules and the end of encryption are the examples we always hear.<\/p>\n

A. Those of us who work on software for quantum computers always want to find more tasks they can do. On the one hand, we want to do more efficiently the things we already know they can do. We\u2019ve known for 30 years that quantum computers can simulate molecules. But it was inefficient. Regarding encryption, I don\u2019t think people should wait 10 years to change their encryption schemes.<\/p>\n

Q. Maybe the day of the big headlines will be when quantum computing breaks traditional encryption. Then we\u2019ll say it has finally arrived.<\/p>\n

A. It is already here now. It\u2019s not having an economic impact now. Its main use so far is to figure out what we will do with future quantum computers.<\/p>\n

Q. What impact will consumers feel directly?<\/p>\n

A. Perhaps a drug. Even in the fields where it\u2019s useful, such as simulating molecules and materials, quantum computers seem good at problems different from those current computers already master. So the most likely outcome is that we will simply do more of those activities: more chemistry, more materials science, because we can discover more.<\/p>\n

Q. The AI boom has triggered astronomical investment<\/a>. Will the same happen with quantum computing?<\/p>\n

A. I would love quantum computing to become that big. But I think its applications won\u2019t be so broad. Everyone sees how AI can be useful in some part of their work. Quantum computing will be very useful, but for fewer things.<\/p>\n

Q. Will it be a smaller sector?<\/p>\n

A. Yes. Think how many people use a supercomputer today. There are some problems that really need a supercomputer to be solved. But most people do not work with one in their day-to-day lives.<\/p>\n

Q. Has all the hype around quantum computers been a problem?<\/p>\n

A. Sometimes people have unrealistic expectations that this will solve every problem in the world. It\u2019s amazing that quantum computers are a possibility, that the way our universe can solve mathematical problems is not what we always imagined. Since the Greeks, we\u2019ve thought solving a mathematical problem meant following step-by-step instructions. If you want to multiply two numbers, you first take these digits, then do this and that. Everyone assumes information must be processed that way. The fact that quantum mechanics says the universe can process information in a very different way, and that we can harness that to solve things we otherwise couldn\u2019t, is thrilling. Whether it will have great economic utility is another question. That it is intellectually thrilling doesn\u2019t mean it will solve every problem, nor that we\u2019ll live like Ant-Man.<\/p>\n

Q. How do you explain quantum then?<\/p>\n

A. It\u2019s as if my job were a magician. Even if it\u2019s crazy, it follows rules. There are things you can\u2019t do.<\/p>\n

Q. You can\u2019t teleport yourself.<\/p>\n

A. No. You could say it\u2019s exciting that there are black holes, but that won\u2019t change your life. But there are indirect uses of quantum computing that could be very interesting. One of my favorites is building fusion reactors. They\u2019ve tried and failed for a very long time. Some think a better approach would be a smaller reactor with a stronger magnet based on new superconductors. Superconductivity is a quantum effect<\/a> in materials that\u2019s poorly understood. There are many mysteries about superconductivity that people have struggled with for a long time, and a quantum computer could help to understand them. So one road to fusion energy could be better superconductors, and one road to that could be quantum computers.<\/p>\n

Q. But is that possible?<\/p>\n

A. Right now I work on improving the simulations that quantum computers perform on materials. And when that works on quantum machines, it will help to understand the materials used in superconductors. There are many steps where that may lead to better fusion energy. I don\u2019t want to promise it will happen, but it\u2019s an example of what we could hope for.<\/p>\n

Q. Has AI led to fewer scientists working on quantum computing?<\/p>\n

A. It\u2019s hard to know because many other things are changing at the same time. Our field is still growing. Would it have grown even faster without AI? It\u2019s hard to say. There have always been people who do a PhD in quantum computing and then work on something else. Previously, they might have gone to work at Google or a financial firm. Today they go to work for an AI company. This happens with physics PhDs all the time.<\/p>\n
