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…
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,…
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…
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…
