The most complex integrated quantum circuit fabricated - Quantum systems getting closer 

01/13/2014 - 04:11


Researchers in the UK, Japan and the Netherlands have fabricated the most functionally complex integrated quantum circuit ever from a single material, capable of generating photons and entangling them at the same time. The circuit consists of two photon sources on a silicon chip that interfere quantum mechanically. Its inventors say that it could be used in quantum information processing applications and in complex on-chip quantum optics experiments.

Quantum interference is at the heart of many quantum information processing algorithms and technologies.
