Synthesis, as well as linear and nonlinear fluorescence properties of 5, 5’-bis(4-N-carbazolylstyryl)-2, 2’-bithiophene [PDF]
Journal of the Serbian Chemical Society, 2004 Anew bithiophene-based organic luminescence material, named 5,5’-bis(4-N-carbazoylstyryl)- 2,2’-bithiophene (BCSBT), was synthesized. Its single-photon excited fluorescence band is located in the range of 520–530 nm, with a quantum yield of around 10 ...

Coherent perfect absorption in deeply subwavelength films in the single-photon regime [PDF]
Nature Communications, 2015 AbstractThe technologies of heating, photovoltaics, water photocatalysis and artificial photosynthesis depend on the absorption of light and novel approaches such as coherent absorption from a standing wave promise total dissipation of energy. Extending the control of absorption down to very low light levels and eventually to the single-photon regime ...

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.

Coherent perfect absorption of path entangled single photons
Optics Express, 2014 We examine the question of coherent perfect absorption (CPA) of single photons, and more generally, of the quantum fields by a {\it macroscopic} medium. We show the CPA of path entangled single photons in a Fabry-Perot interferometer containing an absorptive medium.

Entangled Absorption of a Single Photon with a Single Spin in Diamond
Physical Review Letters, 2015 Quantum entanglement, a key resource for quantum information science, is inherent in a solid. It has been recently shown that entanglement between a single optical photon and a single spin qubit in a solid is generated via spontaneous emission. However, entanglement generation by measurement is rather essential for quantum operations. We here show that

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.

A quantum trajectory picture of single photon absorption and energy transport in photosystem II
The Journal of Chemical Physics, 2023 We use quantum trajectory theory to study the dynamics of the first step in photosynthesis for a single photon interacting with photosystem II (PSII). By considering individual trajectories we are able to look beyond the ensemble average dynamics to compute the PSII system evolution conditioned upon individual photon counting measurements. Measurements

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.

Improvement of infrared single-photon detectors absorptance by integrated plasmonic structures [PDF]
Scientific Reports, 2013 Plasmonic structures open novel avenues in photodetector development. Optimized illumination configurations are reported to improve p-polarized light absorptance in superconducting-nanowire single-photon detectors (SNSPDs) comprising short- and long-periodic niobium-nitride (NbN) stripe-patterns.
