Quantum IT

Quantum Computing Devices

Quantum computing is a technology that uses quantum mechanics principles to enable computations considered impossible with existing computers. NEC was the first to demonstrate a solid-state device capable of integrating quantum bits and create the world's first solid-state 2-bit quantum gate. NEC went on to successfully operate a variable coupling circuit capable of switching the operation between two quantum bits, lining up the required elements for quantum computing. We are currently conducting quantum computing experiments and research for multi-bit implementation across a broad spectrum from quantum physics to quantum algorithms.

Flux qubit device

Devices that combine photonics and electronics through the use of semiconductor quantum dots

Quantum cryptography shows promise as a technology of the future that guarantees unconditional security. The realization of this technology requires quantum information processing of both photons for information transmission and electrons for information computing. Semiconductor quantum dots are strong candidates for realizing such combined processing. We are conducting research to generate pairs of quantum-tangled photons using semiconductor quantum dots and to achieve a quantum information interface between photons and spins.
