Determining the Quantum Expectation Value by Measuring a Single Photon: The first realisation of quantum protective measurements

F. Piacentini, A. Avella, E. Rebufello, R. Lussana, F. Villa, A. Tosi, M. Gramegna, G. Brida, E. Cohen, L. Vaidman, I. P. Degiovanni, M. Genovese Quantum mechanics, one of the keystones of modern physics, exhibits several peculiar properties, differentiating it from classical mechanics. One of the most intriguing is that variables might not have definite values. A complete quantum description provides only probabilities for obtaining various eigenvalues of a quantum variable....

No smooth beginning for spacetime. (arXiv:1705.00192v2 [hep-th] UPDATED)  gr-qc updates on arXiv.org on 2017-8-19 8:40am GMT Authors: Job Feldbrugge, Jean-Luc Lehners, Neil Turok We identify a fundamental obstruction to any theory of the beginning of the universe, formulated as a semiclassical path integral. Hartle and Hawking's no boundary proposal and Vilenkin's tunneling proposal are examples of such theories. Each may be formulated as... Read more →

Adiabatic Theorem for Quantum Spin Systems  PRL: General Physics: Statistical and Quantum Mechanics, Quantum Information, etc. on 2017-8-11 2:00pm GMT Author(s): S. Bachmann, W. De Roeck, and M. Fraas The first proof of the quantum adiabatic theorem was given as early as 1928. Today, this theorem is increasingly applied in a many-body context, e.g., in quantum annealing and in studies...
