Synchronization and Estimation of Gravity‐Induced Time Difference for Quantum Clocks
Synchronization and Estimation of Gravity‐Induced Time Difference for Quantum Clocks
Abstract It has recently been reported that, under an operational definition of time, quantum clocks would get entangled through gravitational effects. Here, an alternative scenario is studied: The clocks have different masses and energy gaps, which would produce time differences via gravitational interaction. The proposal of quantum clock synchronization (QCS) …
