Precision time metrology using non-local properties of quantum entangled states

  • Branch of study: Electrical Engineering and Communications
  • Department: Department of Measurement
    • Description:
      The nonlocal properties of quantum entangled states can be exploited in many ways. The most common use today is in quantum cryptography, specifically in quantum key distribution (QKD) protocols, but the same techniques can also be used in ultraprecise metrology for the transfer of time or positional information. Thus, a high degree of correlation leads to not only more accurate but also more secure transmission of sensitive information.
