The Office of Advanced Research Projects of the U.S. Department of Defense (DARPA) has signed a contract with ColdQuanta to create a new quantum computer.
As we were informed, the construction of a quantum computer for 1000 cubic meters will be possible in the next 40 months.

According to Bo Ewald, CEO of ColdQuanta, within the next 40 months, under the terms of this contract, a machine will be created which will consist of 1000 (one thousand!!!!) cubic meters, and it will be able to make the necessary calculations ... to create the drugs and... (it's not interesting and probably not true that it will be used for this) - and to break the ciphers.

All this suggests that users of today's asymmetric key cryptography have less and less time left. I don't think 1000 kbit will be able to crack a key longer than 2000 bits, but I think 10,000 kbit will appear after a 1000 kbit quantum computer. That's the problem.
In 40 months, the era of quantum cryptography for a strong world and keyless encryption for ordinary people will begin.
If there is much talk about quantum cryptography, then keyless encryption methods are considered fiction and not worthy of public attention.

Is it really possible to have that kind of computers that could do so much cryptography? Really our world now are going through so much in computerization and it will be a matter of fact when all of the advance technology will become more advance. We had already seen heart transplant in medical and there is also a study about head transplant. I do not know if it was being successful but it is indeed true that a certain man who is sick and had having hard time on his condition made him decide to volunteer for the said experiment.

Computerization is really great and hoping that it will be apply to do things for comfort and not just creating it by the purpose of doing evil things.

-------------------
In fact, no matter how much computing power a person invents, no matter how fast the computer that will be used to break cryptography, this battle will always be won by cryptographers, because mathematics is endless now, it can work with any numbers. And technologies are always finite for the present moment in time, so they are always limited in their capabilities.
I pay attention to modern cryptography, and raise the topic of its long or short life, precisely from the point of view of the availability and use of keys for encryption. No matter how perfect cryptography is, the presence of a key always instantly weakens it to zero in the event of an attack. All modern attacks are attacks to steal keys and passwords. And not a single attack from fraudsters - not on cryptography.
All talk about the threat of quantum computing is a false trail.
All conversations should be about how to protect the user from theft of keys, passwords, phishing.
It is this vector - no one discusses or, in the best case, offers "password managers" or two-factor authentication. And that and that way is a utopia, and cyber defenders pumping money out of users. This is their way of being and, moreover, forever. They do not offer a solution to the problem at the root, but polish an outdated mechanism.
I suggest looking the other way.
We need cryptography without a key and authentication without a password, and this means the main thing - without any permanent, long-assigned digital identifier.
