Single-photon absorption by single photosynthetic light-harvesting complexes [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2018 Abstract We provide a unified theoretical approach to the quantum dynamics of absorption of single photons and subsequent excitonic energy transfer in photosynthetic light-harvesting complexes. Our analysis combines a continuous mode

Single-Photon Absorption and Reemission in Two-Level Cold Atoms
The Rochester Conferences on Coherence and Quantum Optics and the Quantum Information and Measurement meeting, 2013 With narrow-band heralded single photons, we demonstrate that the single-photon absorption and reemission processes in a two-level atomic ensemble can be coherently controlled by shaping the incident photon temporal waveform.

Metamaterial coherent plasmonic absorption with a single photon [PDF]
, 2015 With a plasmonic metamaterial absorber of sub-wavelength thickness we demonstrated that coherent absorption can be observed even with a single photon that could be coupled with nearly 100% probability into a localized plasmon.

Infrared single-photon detection by two-photon absorption in silicon
Physical Review B, 2008 We propose a scheme for infrared single-photon detection based on two-photon absorption at room temperature in Si avalanche photodiodes, where the detected photon's energy is lower than the band gap and the energy difference is complemented by a pump field.

Heralded single-photon absorption by a single atom [PDF]
Nature Physics, 2010 The emission and absorption of single photons by single atomic particles is a fundamental limit of matter-light interaction, manifesting its quantum mechanical nature. At the same time, as a controlled process it is a key enabling tool for quantum technologies, such as quantum optical information technology [1, 2] and quantum metrology [3, 4, 5, 6 ...

Cooperative single-photon absorption at interfaces [PDF]
Chemical Physics Letters, 1994 The pairwise absorption of light by chemically distinct molecules in close proximity can result in their cooperative single-photon excitation. It is shown how new characteristics emerge where the two molecular species concerned lie on opposite sides of a phase boundary or interface, as for example with two immiscible liquids, one polar and the other ...

Removal of a single photon by adaptive absorption [PDF]
Physical Review A, 2001 We present a method to remove, using only linear optics, exactly one photon from a field-mode. This is achieved by putting the system in contact with an absorbing environment which is under continuous monitoring. A feedback mechanism then decouples the system from the environment as soon as the first photon is absorbed.
