Spin rephasing extends single-photon storage in quantum memory for future networks

Researchers have proposed a spin rephasing method that lets quantum memory store single-photon states longer, a key building block for future quantum networks that transmit qubits instead of classical bits.

• Spin rephasing extends how long single-photon states survive in quantum memory
• Qubits can be in a superposition of 0 and 1 and become entangled, unlike classical bits
• The work targets efficient quantum information exchange in future networks
