Experimental Proof of Nonlocal Wavefunction Collapse for a Single Particle Using Homodyne Measurement
Maria Fuwa, Shuntaro Takeda, Marcin Zwierz +2
A single quantum particle can be described by a wavefunction that spreads over arbitrarily large distances, but it is never detected in two (or more) places. This strange phenomeno…
Asymptotic entropic uncertainty relations
Radosław Adamczak, Rafał Latała, Zbigniew Puchała +1
We analyze entropic uncertainty relations for two orthogonal measurements on a -dimensional Hilbert space, performed in two generic bases. It is assumed that the unitary matrix…
Quantum computation speedup limits from quantum metrological precision bounds
Rafal Demkowicz-Dobrzanski, Marcin Markiewicz
We propose a scheme for translating metrological precision bounds into lower bounds on query complexity of quantum search algorithms. Within the scheme the link between quadratic p…
On quantum interferometric measurements of temperature
Marcin Jarzyna, Marcin Zwierz
We provide a detailed description of the quantum interferometric thermometer, which is a device that estimates the temperature of a sample from the measurements of the optical phas…
One-Loop Dominance in the Imaginary Part of the Polarizability: Application to Blackbody and Non-Contact van der Waals Friction
U. D. Jentschura, G. Lach, M. De Kieviet +1
Phenomenologically important quantum dissipative processes include black-body friction (an atom absorbs counterpropagating blue-shifted photons and spontaneously emits them in all…
Communication between general-relativistic observers without a shared reference frame
Agata Chȩcińska, Andrzej Dragan
We show how to reliably encode quantum information and send it between two arbitrary general-relativistic observers without a shared reference frame. Any information stored in a qu…
