Connecting up the quantum internet

Major leap for practical building blocks of a quantum internet: New research demonstrates how to dramatically improve the storage time of a telecom-compatible quantum memory, a vital component of a global quantum network. The technology operates in the same 1550 nanometer band as today's telecommunications infrastructure. It can also be operated as a quantum light source or used as an optical link for solid-state quantum computing devices such as superconducting qubits and silicon qubits.
