Enhancing the precision limits of interferometric satellite geodesy missions
npj Microgravity, 2022 Satellite geodesy uses the measurement of the motion of one or more satellites to infer precise information about the Earth’s gravitational field. In this work, we consider the achievable precision limits on such measurements by examining approximate ...

Quantum steering with vector vortex photon states with the detection loophole closed
npj Quantum Information, 2022 Violating a nonlocality inequality enables the most powerful remote quantum information tasks and fundamental tests of quantum physics. Loophole-free photonic verification of nonlocality has been achieved with polarization-entangled photon pairs, but not

A new entropic quantum correlation measure for adversarial systems
Scientific Reports, 2023 Quantum correlation often refers to correlations exhibited by two or more local subsystems under a suitable measurement. These correlations are beyond the framework of classical statistics and the associated classical probability distribution.

Capacities of Quantum Amplifier Channels [PDF]
, 2017 Quantum amplifier channels are at the core of several physical processes. Not only do they model the optical process of spontaneous parametric down-conversion, but the transformation corresponding to an amplifier channel also describes the physics of the
