A new way of creating arrays of ultracold neutral atoms could make it possible to build quantum computers with more than 100,000 quantum bits (qubits) – two orders of magnitude higher than today’s best machines.
Physicists at the University of Stuttgart, Germany have teleported a quantum state between photons generated by two different semiconductor quantum dot light sources located several metres apart.
Physicists in the UK have succeeded in routing and teleporting entangled states of light between two four-user quantum networks – an important milestone in the development of scalable quantum communications.
