Scientists Devise Photon-based Router

Jul 16, 2014 |

Scientists at the Weizmann Institute say they have developed the world’s first photonic router, an important advance towards building a full-on quantum computer. The router is a quantum device based on a single atom that can switch between two states. The single atom is coupled to a fiber-coupled, chip-based microresonator. The state is flipped by Read more…

Quantum Processor Hits 99.9 Percent Reliability Target

Apr 25, 2014 |

Physicists at UC Santa Barbara (UCSB) have taken a huge leap forward towards what they refer to as a “fully functional quantum computer” – long-considered the holy grail of both physics and computing. The five cross-shaped elements are the Xmon variant, so named by the team, of the transmon qubit placed in a linear array. A Read more…

Big Leap Forward for Integrated Quantum Computer

Feb 5, 2014 |

An international team of researchers led by Dr. Mark Thompson from the University of Bristol have for the first time successfully generated and manipulated single photons on a silicon chip – putting them substantially closer to realizing their goal of building a quantum computer. The technique involved shrinking the key components so they could be Read more…
