Quantum computers: IBM installs a new one in Japan

IBM is certainly the leading player in the quantum computer industry . For years it has been active in experimenting with these new, revolutionary technologies. And a new quantum computer , the Quantum System One, was recently installed in the Kawasaki Business Incubation Center in Kawasaki City, Japan.

The difficulty in installing and maintaining these complex systems is above all the cooling system . These are extremely complex systems that a company can hardly operate. To remedy this, IBM usually offers access to applicants via the cloud of its own quantum system, so much so that it is possible to try to program one !

“IBM is committed to growing the global quantum ecosystem and promoting collaboration between diverse research communities. As part of this global effort, I am proud to unveil Japan's most powerful quantum computer and excited to see research contributions to be made by Japan's world-class academic, private sector and government institutions. Together, we can take important steps to accelerate scientific progress in a variety of fields. "

IBM and the new quantum computer in Japan

The only (so far) IBM Quantum System One available is installed in the quantum computing center of Poughkeepsie, in the state of New York, and as mentioned the companies accessed it via the cloud. The only alternative is installation in Germany.

This innovative tool will be made available to those Japanese companies wishing to experiment with quantum computing . An example is the research team of Mitsubishi Chemical, which has created a quantum algorithm to better understand (through targeted simulations) the operation of some chemical compounds aimed at improving the technology of OLED displays .

"Nature isn't classical, damn it, and if you want to do a simulation of nature, you'd better do it using quantum mechanics."

A little background on the origins of Quantum Computers

Quantum computing is the study of a non-classical computation model. On the one hand we have the traditional models, such as the Turing machine, where the calculations are based on classical representations of computational memory. On the other hand we have quantum computation based on the transformation of memory into a superposition of several states of a classical type.

Quantum computing begins in the early 1980s and later Richard Feynman and Jurij Manin express the idea that the quantum computer has the potential to simulate things that a classical computer cannot .

We have an example in 1994, when Peter Shor publishes a quantum algorithm that factorizes integers in polynomial time . It seems trivial but it is not: it is enough to consider that among the most important cryptographic algorithms we find the RSA, which is based on the assumption that the factorization of integers is difficult from a computational point of view and therefore intangible from this point of view.

The existence of the quantum algorithm in polynomial time could prove that one of the most used cryptographic protocols in the world, therefore the RSA, would be vulnerable to a quantum computer and therefore all the current measures applied in the field of computer security would be futile.
