Bell inequality violation in the presence of vacancies and incomplete measurements
Kaila C. S. Hall, Daniel K. L. Oi
The characterization of a quantum system can be complicated by non-ideal measurement processes. In many systems, the underlying physical measurement is only sensitive to a single f…
Entanglement and quantum correlations in many-body systems: a unified approach via local unitary operations
M. Cianciaruso, S. M. Giampaolo, W. Roga +3
Local unitary operations allow for a unifying approach to the quantification of quantum correlations among the constituents of a bipartite quantum system. For pure states, the dist…
Qubit entanglement on a silicon photonic chip
Joshua W. Silverstone, Raffaele Santagati, Damien Bonneau +4
Entanglement--one of the most delicate phenomena in nature--is an essential resource for quantum information applications. Large entangled cluster states have been predicted to ena…
Channel Steering
Marco Piani
We introduce and study the notion of steerability for channels. This generalizes the notion of steerability of bipartite quantum states. We discuss a key conceptual difference betw…
Quantum Optics of Chiral Spin Networks
Hannes Pichler, Tomás Ramos, Andrew J. Daley +1
We study the driven-dissipative dynamics of a network of spin-1/2 systems coupled to one or more chiral 1D bosonic waveguides within the framework of a Markovian master equation. W…
Observation of localized multi-spatial-mode quadrature squeezing in four-wave mixing
C. S. Embrey, M. T. Turnbull, P. G. Petrov +1
Quantum states of light can improve imaging whenever the image quality and resolution are limited by the quantum noise of the illumination. In the case of a bright illumination, qu…
Quantum Spin Dimers from Chiral Dissipation in Cold-Atom Chains
Tomás Ramos, Hannes Pichler, Andrew J. Daley +1
We consider the non-equilibrium dynamics of a driven dissipative spin chain with chiral coupling to a 1D bosonic bath, and its atomic implementation with a two-species mixture of c…
Proceedings 9th Workshop on Quantum Physics and Logic
Ross Duncan, Prakash Panangaden
This volume contains the proceedings of the ninth workshop on Quantum Physics and Logic (QPL2012) which took place in Brussels from the 10th to the 12th of October 2012. QPL2012 br…
Einstein-Podolsky-Rosen steering provides the advantage in entanglement-assisted subchannel discrimination with one-way measurements
Marco Piani, John Watrous
Steering is the entanglement-based quantum effect that embodies the "spooky action at a distance" disliked by Einstein and scrutinized by Einstein, Podolsky, and Rosen. Here we pro…
Quantum trajectories and open many-body quantum systems
Andrew J. Daley
The study of open quantum systems has become increasingly important in the past years, as the ability to control quantum coherence on a single particle level has been developed in…
Unlearning Quantum Information
Daniel K. L. Oi
Quantum dynamics can be driven by measurement. By constructing measurements that gain no information, effective unitary evolution can be induced on a quantum system, for example in…
Quantumness of correlations, quantumness of ensembles and quantum data hiding
Marco Piani, Varun Narasimhachar, John Calsamiglia
We study the quantumness of correlations for ensembles of bi- and multi-partite systems and relate it to the task of quantum data hiding. Quantumness is here intended in the sense…
Experimental Implementation of a Quantum Optical State Comparison Amplifier
Ross J. Donaldson, Robert J. Collins, Electra Eleftheriadou +3
Quantum optical amplification that beats the noise addition limit for deterministic amplifiers has been realized experimentally using several different nondeterministic protocols.…
A minimum control ancilla driven quantum computation scheme with repeat-until-success style gate generation
Kerem Halil-Shah, Daniel K. L. Oi
Some two qubit interactions are singly sufficient for universal quantum computation but not without the use of an ancilla. Recent schemes for universal quantum computation have foc…
