Entanglement's Benefit Survives an Entanglement-Breaking Channel
Zheshen Zhang, Maria Tengner, Tian Zhong +2
Entanglement is essential to many quantum information applications, but it is easily destroyed by quantum decoherence arising from interaction with the environment. We report the f…
A single-crystal source of path-polarization entangled photons at non-degenerate wavelengths
S. Sauge, M. Swillo, M. Tengner +1
We demonstrate a bright, narrowband, compact, quasi-phase-matched single-crystal source generating path-polarization-entangled photon pairs at 810 nm and 1550 nm at a maximum rate…
Robust quantum cryptography with a heralded single-photon source based on the decoy-state method
Qin Wang, Wei Chen, Guilherme Xavier +7
In this paper, we describe a robust quantum cryptography scheme with a heralded single photon source based on the decoy-state method, which has been shown by numerical simulations…
Characterization of an asynchronous source of heralded single photons generated at a wavelength of 1550 nm
Maria Tengner, Daniel Ljunggren
We make a thorough analysis of heralded single photon sources regarding how factors such as the detector gate-period, the photon rates, the fiber coupling efficiencies, and the sys…
Narrowband polarization-entangled photon pairs distributed over a WDM link for qubit networks
S. Sauge, M. Swillo, S. Albert-Seifried +5
We present a bright, narrowband, portable, quasi-phase-matched two-crystal source generating polarization-entangled photon pairs at 809 nm and 1555 nm at a maximum rate of 1.2 10^6…
Theory and experiment of entanglement in a quasi-phase-matched two-crystal source
Daniel Ljunggren, Maria Tengner, Philip Marsden +1
We report new results regarding a source of polarization entangled photon-pairs created by the process of spontaneous parametric downconversion in two orthogonally oriented, period…
