Encrypted quantum correlations: Delayed choice of quantum statistics and other applications
Manuel Gessner, Augusto Smerzi
In a three-particle extension of Wheeler's delayed choice gedanken experiment, the quantum statistics of two particles is undetermined until a third particle is measured. As a func…
A relational time-symmetric framework for analyzing the quantum computational speedup
Giuseppe Castagnoli, Eliahu Cohen, Artur Ekert +1
The usual representation of quantum algorithms is limited to the process of solving the problem. We extend it to the process of setting the problem. Bob, the problem setter, select…
Multiparameter squeezing for optimal quantum enhancements in sensor networks
Manuel Gessner, Augusto Smerzi, Luca Pezzè
Squeezing currently represents the leading strategy for quantum enhanced precision measurements of a single parameter in a variety of continuous- and discrete-variable settings and…
Phase-space inequalities beyond negativities
Martin Bohmann, Elizabeth Agudelo
We derive a family of inequalities involving different phase-space distributions of a quantum state which have to be fulfilled by any classical state. The violation of these inequa…
Entanglement distance for an arbitrary state of M qubits
Denise Cocchiarella, Stefano Scali, Salvatore Ribisi +3
We propose a measure of entanglement that can be computed for any pure state of an -qubit system. The entanglement measure has the form of a distance that we derive from an adap…
Conditional nonclassical field generation in cavity QED
Karsten Weiher, Elizabeth Agudelo, Martin Bohmann
We introduce a method for the conditional generation of nonclassical states of light in a cavity. We consider two-level atoms traveling along the transverse direction to the cavity…
