Decoherence effects in non-classicality tests of gravity
Simone Rijavec, Matteo Carlesso, Angelo Bassi +2
The experimental observation of a clear quantum signature of gravity is believed to be out of the grasp of current technology. However, several recent promising proposals to test t…
Interference in the Heisenberg Picture of Quantum Field Theory, Local Elements of Reality and Fermions
Chiara Marletto, Nicetu Tibau Vidal, Vlatko Vedral
We describe the quantum interference of a single photon in the Mach-Zehnder interferometer using the Heisenberg picture. Our purpose is to show that the description is local just l…
Emergence of Constructor-based Irreversibility in Quantum Systems: Theory and Experiment
Chiara Marletto, Vlatko Vedral, Laura Knoll +7
The issue of irreversibility in a universe with time-reversal-symmetric laws is a central problem in physics. % , and, in particular, to statistical mechanics, information theory a…
The information-theoretic foundation of thermodynamic work extraction
Chiara Marletto
In this paper I apply newly-proposed information-theoretic principles to thermodynamic work extraction. I show that if it is possible to extract work deterministically from a physi…
Transforming pure and mixed states using an NMR quantum homogeniser
Maria Violaris, Gaurav Bhole, Jonathan A. Jones +2
The universal quantum homogeniser can transform a qubit from any state to any other state with arbitrary accuracy, using only unitary transformations to perform this task. Here we…
The Quantum Totalitarian Property and Exact Symmetries
Chiara Marletto, Vlatko Vedral
We discuss a point, which from time to time has been doubted in the literature: all symmetries, such as those induced by the energy and momentum conservation laws, hold in quantum…
On the testability of the equivalence principle as a gauge principle detecting the gravitational phase
C. Marletto, V. Vedral
There have been various claims that the Equivalence Principle, as originally formulated by Einstein, presents several difficulties when extended to the quantum domain, even in the…
Witnessing non-classicality beyond quantum theory
Chiara Marletto, Vlatko Vedral
We propose a general argument to show that if a physical system can mediate locally the generation of entanglement between two quantum systems, then it itself must be non-classical…
Non-monogamy of spatio-temporal correlations and the black hole information loss paradox
C. Marletto, V. Vedral, S. Virzì +6
Pseudo-density matrices are a generalisation of quantum states and do not obey monogamy of quantum correlations. Could this be the solution to the paradox of information loss durin…
Sagnac Interferometer and the Quantum Nature of Gravity
Chiara Marletto, Vlatko Vedral
We use a quantum variant of the Sagnac interferometer to argue for the quantum nature of gravity as well as to formulate a quantum version of the equivalence principle. We first pr…
