A quantum computer, dubbed the ultimate computer that can process information at a speed 100 million times faster than a supercomputer, is attracting global attention.
If the quantum computer is actually produced, there will be an "information communication revolution" because it can also be applied to cipher technology, industry analysts said.
NTT Corp. and NEC Corp. are leading other companies in developing the quantum computer, but the analysts said it will take several decades before their research can be put into practical use.
