Storage of hyperentanglement in a solid-state quantum memory
Alexey Tiranov, Jonathan Lavoie, Alban Ferrier +11
Two photons can simultaneously share entanglement between several degrees of freedom such as polarization, energy-time, spatial mode and orbital angular momentum. This resource is…
Efficient Bell state analyzer for time-bin qubits with fast-recovery WSi superconducting single photon detectors
Raju Valivarthi, Itzel Lucio-Martinez, Allison Rubenok +9
We experimentally demonstrate a high-efficiency Bell state measurement for time-bin qubits that employs two superconducting nanowire single-photon detectors with short dead-times,…
Phonon counting and intensity interferometry of a nanomechanical resonator
Justin D. Cohen, Sean M. Meenehan, Gregory S. MacCabe +5
Using an optical probe along with single photon detection we have performed effective phonon counting measurements of the acoustic emission and absorption processes in a nanomechan…
Spectral Correlation Measurements at the Hong-Ou-Mandel Interference Dip
Thomas Gerrits, Francesco Marsili, Varun Verma +4
We present an efficient tool capable of measuring the spectral correlations between photons emerging from a Hong-Ou-Mandel interferometer. We show that for our spectrally factoriza…
Quantum storage of entangled telecom-wavelength photons in an erbium-doped optical fibre
Erhan Saglamyurek, Jeongwan Jin, Varun B. Verma +5
The realization of a future quantum Internet requires processing and storing quantum information at local nodes, and interconnecting distant nodes using free-space and fibre-optic…
High-efficiency WSi superconducting nanowire single-photon detectors operating at 2.5 K
V. B. Verma, B. Korzh, F. Bussières +7
We investigate the operation of WSi superconducting nanowire single-photon detectors (SNSPDs) at 2.5 K, a temperature which is ~ 70 % of the superconducting transition temperature…
On-Chip Detection of Entangled Photons by Scalable Integration of Single-Photon Detectors
Faraz Najafi, Jacob Mower, Nicholas Harris +8
Photonic integrated circuits (PICs) have emerged as a scalable platform for complex quantum technologies using photonic and atomic systems. A central goal has been to integrate pho…
Direct generation of three-photon polarization entanglement
Deny R. Hamel, Lynden K. Shalm, Hannes Hübel +7
Non-classical states of light are of fundamental importance for emerging quantum technologies. All optics experiments producing multi-qubit entangled states have until now relied o…
Superconducting nanowire single photon detectors fabricated from an amorphous Mo0.75Ge0.25 thin film
V. B. Verma, A. E. Lita, M. R. Vissers +4
We present the characteristics of superconducting nanowire single photon detectors (SNSPDs) fabricated from amorphous Mo0.75Ge0.25 thin-films. Fabricated devices show a saturation…
Quantum teleportation from a telecom-wavelength photon to a solid-state quantum memory
Felix Bussieres, Christoph Clausen, Alexey Tiranov +11
In quantum teleportation, the state of a single quantum system is disembodied into classical information and purely quantum correlations, to be later reconstructed onto a second sy…
