EPJ Quantum Technology: New Review Article The Deep Space Quantum Link (DSQL)

A new review lays out a roadmap for quantum technologies. Credit: Robert Lea

Space-based quantum optical links support future networking applications for quantum sensing, quantum communications, and quantum information science. In addition, such links enable new scientific experiments impossible to reach in terrestrial experiments. The Deep Space Quantum Link (DSQL) is a spacecraft mission concept that aims to use extremely long-baseline quantum optical links to test fundamental quantum physics in novel special and general relativistic regimes.

In a new Review article just published in EPJ Quantum Technology, an international author team provide an overview of a two-year long study of how quantum optics in space could be used to conduct new tests of fundamental physics, in compliment to proposed tests utilizing matter or clocks. The manuscript describes the findings of the NASA-funded study, and describes some of the technology requirements and outstanding mission design studies necessary to move forward with the mission.
