We are continuously sending information to each other, transmitting zeros and ones through a giant network of connected computers and devices. Scientists are now trying to extend this familiar concept of the internet to the quantum realm, looking for an efficient way to exchange quantum rather than classical information: qubits instead of bits. The motivation is not just scientific curiosity. Qubits can be a 0, a 1 or any superposition of the two. They can also become entangled, showing a degree of correlation that is out of reach for classical bits.
Spin rephasing helps quantum memories store single-photon states longer for future networks
