Japan Opens Prototype Quantum Computing System for Public, Worldwide Use

[Raevenlord]

Japan's Nippon Telegraph and Telephone Company (NTT) is opening up its prototype quantum computing system for public use over the internet, giving users around the world access to one of the most elusive pieces of tech that this world has yet seem. Maybe we haven't seen it, though; observation does change the outcome, and these quantum physics really are as finicky as they come. Starting Nov. 27, Japan joins China and the U.S. in the race to develop the world's most advanced computers - and Japan has chosen the free, quantum-democratizing approach.

The NTT quantum computing solution is a state-sponsored research project, developed in conjunction with the National Institute of Informatics, Osaka university, and other partners. It has taken a different technical approach from other quantum computing developers, in that this particular computing system is exploiting the properties of light. Widely (un)known as Linear Optics Quantum Computation (LOQC), this particular approach foregoes qubits (which are extremely difficult to keep from decohering, and usually require very exotic cooling techniques to increase the qubits' stability. LOQC abandons qubits and uses photons to represent them as information carriers through linear optical elements (such as beam splitters, phase shifters, and mirrors). This allows the machine to process quantum information, using photon detectors and quantum memories to detect and store quantum information.





As a major upside, this approach also makes the machine capable of operating stably, around the clock, at room temperature, which is the reason public usage is now being rolled out. The aim is to test a range of uses and have this tie into developing software, and there's much to say about the usage of quantum computers for that purpose: in cases where a supercomputer would consume 10,000kW of power, NTT's prototype would use just 1kW - some tech enthusiasts use PSUs that are way more powerful than that.

They could optimize emulators and operating systems, and popular software. That's what I would do at least.

It's probably no good for that.

japan ... small country without resources. old population, debt,.. crapy life according some Vlogers on youtube witch try live there..horrible they say
this "races" only make more unemployed over population across planet

It's probably no good for that.

Considering the nature of quantum calculations it would be great at determining the most efficient way to do things.

That's assuming this is a functional quantum computer with any amount of power and not more of a prototype, which it probably is.

Any evidence for this or just ancedotes?

There are some social/cultural and employment issues but as a whole Japan is significantly ahead of the vast majority of countries.

Maybe... one day... one of the billions of people on the internet will actually find a use for it. Good thinking, Japan.

In fact, at least, Japan’s unemployment rate is the lowest among the OECD countries.

This is actually really nice .. I'm also wondering why someone uses this to attack a whole country. Strange

And exactly how many of you have been to Japan? I have been multiple times and it's a nice place with nice people and I would happily go back again.
Do they have some issues? For sure, but so does every nation on this planet.
Is the government xenophobic? For sure, but it doesn't mean all the Japanese are.
Just because you don't understand their culture etc. doesn't make them bad people.
