Silicon Qubits Entangled Over a Half a Centimeter | NextBigFuture.com

Princeton researchers connected silicon qubits using a narrow cavity in a “wire”. It contained a single particle of light, or photon, that picks up the message from one qubit and transmits it to the next qubit. Above – Researchers at Princeton University have made an important step forward in the quest to build a quantum computer using silicon components, which are prized for their low cost and versatility compared to the hardware in today’s quantum computers. The team showed that a silicon-spin quantum bit (shown in the box) can communicate with another quantum bit located a significant distance away on
