Coherent absorption of N00N states [PDF]
, 2016 Recent results in deeply subwavelength thickness films demonstrate coherent control and logical gate operations with both classical and single-photon light sources.

Physical Review Research, 2023 The ability to detect single photons has become increasingly essential due to the rise of photon-based quantum computing. In this theoretical work, we propose a system consisting of a quantum dot (QD) side-coupled to a superconducting nanowire.

Two-photon-absorption measurements in the presence of single-photon losses
Physical Review A, 2022 We discuss how two-photon absorption (TPA) of squeezed and coherent states of light can be detected in measurements of the transmitted light fields. Such measurements typically suffer from competing loss mechanisms such as experimental imperfections and linear scattering losses inside the sample itself, which can lead to incorrect assessments of the ...

Energy Relaxtation and Hot Spot Formation in Superconducting Single Photon Detectors SSPDS
EPJ Web of Conferences, 2015 We have studied the mechanism of energy relaxation and resistive state formation after absorption of a single photon for different wavelengths and materials of single photon detectors. Our results are in good agreement with the hot spot model.

OPTIMIZED SUPERCONDUCTING NANOWIRE SINGLE PHOTON DETECTORS TO MAXIMIZE ABSORPTANCE
Progress In Electromagnetics Research B, 2016 Dispersion characteristics of four types of superconducting nanowire single photon detectors, nano-cavity-array- (NCA-), nano-cavity-deflector-array- (NCDA-), nano-cavity-double-deflector-array- (NCDDA-) and nano-cavity-trench-array- (NCTA-) integrated (I-A-SNSPDs) devices was optimized in three periodicity intervals commensurate with half-, three ...

Photon entanglement detection by a single atom
New Journal of Physics, 2013 We use a single trapped ^40 Ca ^+ ion as a resonant, polarization-sensitive absorber to detect and characterize the entanglement of tunable narrowband photon pairs from a spontaneous parametric down-conversion source.

Photon transport through a nanohole by a moving atom
New Journal of Physics, 2016 We have proposed and investigated for the first time an efficient way of photon transport through a subwavelength hole by a moving atom. The transfer mechanism is based on the reduction of the wave packet of a single photon due to its absorption by an ...

Current-Assisted SPAD with Improved p-n Junction and Enhanced NIR Performance
Sensors, 2020 Single-photon avalanche diodes (SPADs) fabricated in conventional CMOS processes typically have limited near infra-red (NIR) sensitivity. This is the consequence of isolating the SPADs in a lowly-doped deep N-type well.

Quantum Single-Photon Control, Storage, and Entanglement Generation with Planar Atomic Arrays
PRX Quantum, 2021 While artificially fabricated patterned metasurfaces are providing paradigm-shifting optical components for classical light manipulation, strongly interacting, controllable, and deterministic quantum interfaces between light and matter in free space ...
