Quantum-secured imaging

Mehul Malik, Omar S. Magaña-Loaiza, Robert W. Boyd

We have built an imaging system that uses a photon's position or time-of-flight information to image an object, while using the photon's polarization for security. This ability all…

EPR-based ghost imaging using a single-photon-sensitive camera

Reuben S. Aspden, Daniel S. Tasca, Robert W. Boyd +1

Correlated-photon imaging, popularly known as ghost imaging, is a technique whereby an image is formed from light that has never interacted with the object. In ghost imaging experi…

Pre-management of Disentanglement

Xiao-Feng Qian

We define threshold disentanglement (TD) as the level above which entanglement must be maintained for later use and calculate the values of quantum system parameters at that…

Effects of Quantum Error Correction on Entanglement Sudden Death

Muhammed Yönaç, J. H. Eberly

We investigate the effects of error correction on non-local quantum coherence as a function of time, extending the study by Sainz and Björk. We consider error correction of amplitu…

Initial Conditions and Entanglement Sudden Death

Xiao-Feng Qian, J. H. Eberly

We report results bearing on the behavior of non-local decoherence and its potential for being managed or even controlled. The decoherence process known as entanglement sudden deat…

A statistical portrait of the entanglement decay of two-qubit memories

Karen M. Fonseca-Romero, Julián Martínez-Rincón, Carlos Viviescas

We present a novel approach to the study of entanglement decay, which focuses on collective properties. As an example, we investigate the entanglement decay of a two-qubit system,…

Maximizing genuine multipartite entanglement of N mixed qubits

S. Agarwal, S. M. Hashemi Rafsanjani

Beyond the simplest case of bipartite qubits, the composite Hilbert space of multipartite systems is largely unexplored. In order to explore such systems, it is important to derive…

Violation of Continuous Variable EPR Steering with Discrete Measurements

James Schneeloch, P. Ben Dixon, Gregory A. Howland +2

In this Letter, we derive an entropic Einstein-Podolsky-Rosen (EPR) steering inequality for continuous variable (CV) systems using only experimentally measured discrete probability…

Improving the performance of bright quantum dot single photon sources using amplitude modulation

Serkan Ates, Imad Agha, Angelo Gulinatti +3

Single epitaxially-grown semiconductor quantum dots have great potential as single photon sources for photonic quantum technologies, though in practice devices often exhibit non-id…

Witnessing non-classicality of a quantum oscillator state by coupling it to a qubit

S. Agarwal, J. H. Eberly

We propose a new witness operation for the non-classical character of a harmonic oscillator state. The method does not require state reconstruction. For all harmonic oscillator sta…

Near-Perfect Sorting of Orbital Angular Momentum and Angular Position States of Light

Malcolm N. O'Sullivan, Mohammad Mirhosseini, Mehul Malik +1

We present a novel method for efficient sorting of photons prepared in states of orbital angular momentum (OAM) and angular position (ANG). A log-polar optical transform is used in…

Genuinely Multipartite Concurrence of N-qubit X-matrices

S. M. Hashemi Rafsanjani, M. Huber, C. J. Broadbent +1

We find an algebraic formula for the N-partite concurrence of N qubits in an X-matrix. X- matricies are density matrices whose only non-zero elements are diagonal or anti-diagonal…

Two-photon interference using background-free quantum frequency conversion of single photons from a semiconductor quantum dot

Serkan Ates, Imad Agha, Angelo Gulinatti +4

We show that quantum frequency conversion (QFC) can overcome the spectral distinguishability common to inhomogeneously broadened solid-state quantum emitters. QFC is implemented by…

Weak values are universal in von Neumann measurements

J. Dressel, A. N. Jordan

We refute the widely held belief that the quantum weak value necessarily pertains to weak measurements. To accomplish this, we use the transverse position of a beam as the detector…

Full characterisation of polarisation states of light via direct measurement

Jeff Z. Salvail, Megan Agnew, Allan S. Johnson +3

Ascertaining the physical state of a system is vital in order to understand and predict its behaviour. Tomography is a standard approach used to determine the form of an unknown st…

Null Values and Quantum State Discrimination

Oded Zilberberg, Alessandro Romito, David J. Starling +4

We present a measurement protocol for discriminating between two different quantum states of a qubit with high fidelity. The protocol, called null value, is comprised of a projecti…

Influence of Atmospheric Turbulence on Optical Communications using Orbital Angular Momentum for Encoding

Mehul Malik, Malcolm O'Sullivan, Brandon Rodenburg +5

We describe an experimental implementation of a free-space 11-dimensional communication system using orbital angular momentum (OAM) modes. This system has a maximum measured OAM ch…

Tavis-Cummings model beyond the rotating wave approximation: Quasi-degenerate qubits

S. Agarwal, S. M. Hashemi Rafsanjani, J. H. Eberly

The Tavis-Cummings model for more than one qubit interacting with a common oscillator mode is extended beyond the rotating wave approximation (RWA). We explore the parameter regime…
