Testing the weak equivalence principle for nonclassical matter with torsion balances
Roberto Onofrio, Alexander R. H. Smith, Lorenza Viola
We propose tests of the weak equivalence principle (WEP) using a torsion balance, in which superposition of energy eigenstates are created in a controllable way for the test masses…
Gravitational waves affect vacuum entanglement
Qidong Xu, Shadi Ali Ahmad, Alexander R. H. Smith
The entanglement harvesting protocol is an operational way to probe vacuum entanglement. This protocol relies on two atoms, modelled by Unruh-DeWitt detectors, that are initially u…
Quantum time dilation: A new test of relativistic quantum theory
Alexander R. H. Smith
A novel quantum time dilation effect is shown to arise when a clock moves in a quantum superposition of two relativistic velocities. This effect is argued to be measurable using ex…
Quantum satellites and tests of relativity
Piergiovanni Magnani, Matteo Schiavon, Alexander R. H. Smith +5
Deployment of quantum technology in space provides opportunities for new types of precision tests of gravity. On the other hand, the operational demands of such technology can make…
Communicating without shared reference frames
Alexander R. H. Smith
We generalize a quantum communication protocol introduced by Bartlett et al. [New. J. Phys. 11, 063013 (2009)] in which two parties communicating do not share a classical reference…
Entangling detectors in anti-de Sitter space
Laura J. Henderson, Robie A. Hennigar, Robert B. Mann +2
We examine in -dimensional anti-de Sitter (AdS) space the phenomena of entanglement harvesting - the process in which a pair of detectors (two-level atoms) extract entanglem…
