Industry committee  —I know that interrupting is not the right thing to do in your committee, but I feel I need to say something, which is that there's this myth that quantum computers are so vastly more powerful than classical computers that they can solve everything, exponentially faster. That is

Industry committee  I said that, yes.

Industry committee  Well, it means that if nothing changes, then not only is the past an open book when a quantum computer becomes available...and as I said, there is nothing you can do to prevent that. It's gone. The past is gone. Forget about it. But if you take no action now, then in 10 years, wh

Industry committee  Thank you, Mr. Gagnon‑Gordillo. That's very good, what you just said. Yes, there are prototypes at the moment that we can buy. We can also rent specialized access time. These prototypes work with a relatively small number of qubits, or quantum bits, for example 127 qubits. If w

Industry committee  I think what I've said so far has been very clear; the answer is yes. It's a catastrophe in the making. If we don't do something, it will be the apocalypse.

Industry committee  I agree.

Industry committee  May I answer?

Industry committee  First, there is a small misinterpretation because quantum cryptography does not in any way serve to break the cryptographic mechanisms currently in use. Quantum cryptography provides an alternative, which is unquestionably secure, as has been demonstrated. That said, conventiona

Industry committee  As I said, we can't know. It's really a guessing game. The fear is that it will be built within 10 years. It's not guaranteed, but there's a good chance it will be, and 10 years from now is tomorrow.

Industry committee  Since I'm a theoretician, I'm very comfortable with your question. The short answer is that what I talked about at length, this “harvest now and decrypt later” strategy, is not a threat to ransomware, because to do ransomware, you need to do it today. It is not as if, in 10 year

Industry committee  In my view, quantum cryptography will definitely be the first application. It's not for the future, because it's already functional. As I said, China is taking it very seriously. So it's a real application that's already functional for protecting information. With respect to qua

Industry committee  I would say that the most important thing is to let researchers expand their imaginations, because that's what makes real progress possible. As the physicist Einstein said: “Imagination is more important than knowledge.” The more you tell people what to do, the less progress y

Industry committee  It depends on what you want to do. You may want to either develop a quantum computer or you may want to develop a quantum Internet, which another speaker mentioned. A quantum Internet would connect all countries, even the whole Earth, to be linked by a quantum network in the same

Industry committee  “When” is a very difficult question. There are so many technological challenges before this can be achieved. I'm a theoretician, so I'm not the right person to ask. However, there are some people who are more knowledgeable than me, like Michele Mosca—who, by the way, should have

Industry committee  They're probably not.
