Holographic formulation of quantum general relativity [PDF]
Physical Review D, 2000 The Lorentzian boundary conditions have been extended to a much more general class, more details given of quantization in the Lorentzian ...

Quantum Mechanics and the Metrics of General Relativity [PDF]
Foundations of Physics, 2005 A one-to-one correspondence is established between linearized space-time metrics of general relativity and the wave equations of quantum mechanics. Also, the key role of boundary conditions in distinguishing quantum mechanics from classical mechanics will emerge naturally from the procedure.

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.

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

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
