Broadband indistinguishability from bright parametric downconversion in a semiconductor waveguide
T. Günthner, B. Pressl, K. Laiho +5
Parametric downconversion (PDC) in semiconductor Bragg-reflection waveguides (BRW) is routinely exploited for photon-pair generation in the telecommunication range. Contrary to man…
Quantumness of Gaussian Discord: Experimental Evidence and Role of System-Environment Correlations
Vanessa Chille, Niall Quinn, Christian Peuntinger +5
We provide experimental evidence of quantum features in bi-partite states classified as entirely classical according to a conventional criterion based on the Glauber P-function but…
Dynamically Controlled Resonance Fluorescence from a Doubly Dressed Solid-State Single Emitter
Yu He, Y. -M. He, J. Liu +8
We report the first experimental demonstration of interference-induced spectral line elimination predicted by Zhu and Scully [Phys. Rev. Lett. 76, 388 (1996)] and Ficek and Rudolph…
Tomography by noise
G. Harder, D. Mogilevtsev, N. Korolkova +1
We present an efficient and robust method for the reconstruction of photon number distributions by using solely thermal noise as a probe. The method uses a minimal number of pre-ca…
Quantum dynamics in a tiered non-Markovian environment
Amir Fruchtman, Brendon W. Lovett, Simon C. Benjamin +1
We introduce a new analytical method for studying the open quantum systems problem of a discrete system weakly coupled to an environment of harmonic oscillators. Our approach is ba…
Nonexistence of entangled continuous-variable Werner states with positive partial transpose
Daniel McNulty, Richard Tatham, Ladislav Mišta
We address an open question about the existence of entangled continuous-variable (CV) Werner states with positive partial transpose (PPT). We prove that no such state exists by sho…
