Abstract

A quantum network will enable fundamentally new capabilities by linking remotely located quantum processors. NIST has recently funded a 5-year program to build a prototype system of linked superconducting qubits. With such a system in hand, it will be possible to study the metrology and standards necessary to support future networks. A major technological challenge is faithfully converting quantum information stored in the superconducting qubits to optical photons.  One promising scheme involves using surface acoustic wave cavities and semiconductor quantum dots.
