"It has hitherto been difficult to switch the movement of one bit and two bits in the same quantum bit, although the bit's movements in the state of one single bit and the coupling of two bits have been confirmed," explained researcher Jaw-Shen Tsai of NEC.

Having been employed at NEC for the past 24 years, Tsai anticipates quantum computing to continue to have a significant role in NEC's research and development efforts.

"NEC has been supporting this project for the past 10 years," he said."One of the main businesses of NEC's is information processing, so naturally I would think the top management would support such a revolution of information processing, and I'm not surprised that they are supporting this project."

But there is still a long way to go before quantum computing becomes a reality, Tsai said.With ongoing improvements in conventional computers and their applications, Tsai expects the development of a practical quantum computer to be more than ten years away.

Meanwhile, the researchers are making plans for more complicated quantum computation that involve more computation steps and more qubits, in order to create a more realistic system and keep abreast of competition from other laboratories in the U.S. and Europe.

"In this particular technology, we have achieved a lot in the past.But many other labs are developing fast, so competition is there and we hope we can keep producing things, like what we have just disclosed, in the future," Tsai said.
