Description
Six authors led by Jonas Zatsch build a light chip that can both make and read quantum states for a future network. Quantum nets need nodes that prep linked light states and send them down fibre lines. Their chip is built on a silicon base that suits the light waves used in phone fibre. It can work in both ways, as a sender and as a receiver, which few chips can claim.
On the chip, paired light states were made and fed into fibres with high faith to the aim state. The team then made a linked group state on one node and read it in full on a second node. Faith there hit 90 percent, which proves linked states can cross from chip to chip. Two-way work makes the chip a fit hub for a full light-based quantum net.
