Spin Rephasing Helps Quantum Memories Store Single-Photon States Longer for Future Networks

Spin rephasing helps quantum memories store single-photon states longer for future networks

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 tw…

Spin rephasing pushes solid-state quantum memory to record single-photon

The vision of a quantum internet, a global network in which information is carried not by classical bits but by qubits that can exist in superpositions of zero and one, has moved one step closer to reality. Researchers at ICFO-The Institute of Photonic Sciences in Barcelona have demonstrated that a solid-state quantum memory can store […]
