Nippon Telegraph and Telephone (NTT) has announced that it will open up a prototype quantum computing system for free public use over the internet.
According to the Nikkei Asian Review, the quantum neural network prototype has been deemed ready to open to the public after becoming capable of operating stably around the clock at room temperature.
Contrary to the approach adopted by Google and other developers, NTT’s device is said to exploits the properties of light.
The Tokyo-based company has been working on a state-sponsored research project in quantum computing with the National Institute of Informatics and others.
NTT’s aim is to test a range of uses and have this embedded into the developing software. The advancement of this brings Japan into an elite league of other two nations – namely the U.S. and China – in a race to develop the world’s most advanced computers.
Existing semiconductor-based computers are nearing their speed and power-consumption limits, thus calling for an international rush to develop new quantum technology to offset the same.
Problems that would take today’s supercomputers thousands of years to solve could be dispatched by quantum computers in minutes. Such ultrafast processing would help unlock the potential of artificial intelligence.
According to a Nikkei Asian Review report, NTT’s prototype consumes just 1kW of power compared to that of a 10,000kW supercomputer.
Japan has so far earmarked about $267 million for quantum computing over a decade beginning in fiscal 2018.
