A quantum-assisted master clock in the sky: global synchronization from satellites at sub-nanosecond precision
Sage Ducoing, Ivan Agullo, James E. Troupe +1
This article develops a protocol to synchronize clocks on board a network of satellites equipped with quantum resources. We show that, in such a constellation, satellites reinforce…
Synchronizing clocks via satellites using entangled photons: Effect of relative velocity on precision
Stav Haldar, Ivan Agullo, James E. Troupe
A satellite-based scheme to perform clock synchronization between ground stations spread across the globe using quantum resources was proposed in [Phys. Rev. A 107, 022615 (2023)],…
Quantum Clock Synchronization for Future NASA Deep Space Quantum Links and Fundamental Science
James Troupe, Stav Haldar, Ivan Agullo +1
The ability to measure, hold and distribute time with high precision and accuracy is a foundational capability for scientific exploration. Beyond fundamental science, time synchron…
Global Time Distribution via Satellite-Based Sources of Entangled Photons
Stav Haldar, Ivan Agullo, Anthony J. Brady +3
We propose a satellite-based scheme to perform clock synchronization between ground stations spread across the globe using quantum resources. We refer to this as a quantum clock sy…
Classical Simulated Annealing Using Quantum Analogues
Brian R. La Cour, James E. Troupe, Hans M. Mark
In this paper we consider the use of certain classical analogues to quantum tunneling behavior to improve the performance of simulated annealing on a discrete spin system of the ge…
Asymmetric delay attack on an entanglement-based bidirectional clock synchronization protocol
Jianwei Lee, Lijiong Shen, Alessandro Cerè +3
We demonstrate an attack on a clock synchronization protocol that attempts to detect tampering of the synchronization channel using polarization-entangled photon pairs. The protoco…
