Quantum tests of the foundations of general relativity [PDF]
Classical and Quantum Gravity, 1998 The role of the equivalence principle in the context of non-relativistic quantum mechanics and matter wave interferometry, especially atom beam interferometry, will be discussed. A generalised form of the weak equivalence principle which is capable of covering quantum phenomena too, will be proposed.

Clocks without “Time” in Entangled-State Experiments
Entropy, 2020 Entangled states of light exhibit measurable correlations between light detections at separated locations. These correlations are exploited in entangled-state quantum key distribution.

ON THE RUNNING OF THE COSMOLOGICAL CONSTANT IN QUANTUM GENERAL RELATIVITY [PDF]
Modern Physics Letters A, 2010 We present arguments that show what the running of the cosmological constant means when quantum general relativity is formulated following the prescription developed by Feynman.

Why we need to quantise everything, including gravity
npj Quantum Information, 2017 Why we need to quantise everything, including gravity Quantum gravity—the theory that will merge quantum theory and general relativity—is yet to be found.

Unconventional reconciliation path for quantum mechanics and general relativity
IET Quantum Communication, 2022 Physics in general is successfully governed by quantum mechanics at the microscale and principles of relativity at the macroscale. Any attempts to unify them using conventional methods have somewhat remained elusive for nearly a century up to the present

General Continuity Bounds for Quantum Relative Entropies
2023 IEEE International Symposium on Information Theory (ISIT), 2023 9 pages, 1 figure. This is a short version of the paper arXiv:2208.00922 with an additional new entropic uncertainty relation.

Constraints on Gravitation from Causality and Quantum Consistency
Advances in High Energy Physics, 2018 We examine the role of consistency with causality and quantum mechanics in determining the properties of gravitation. We begin by examining two different classes of interacting theories of massless spin 2 particles—gravitons.

On the Inaccessibility of Time Machines
Universe, 2023 We will explain why time machines, although allowed in General Relativity, cannot be accessed by observers once we include quantum effects. Moreover, we will show that traversable wormholes cannot be turned into time machines without invoking the effects
