Indistinguishable photons from a single molecule.

Indistinguishable near-infrared single photons from an individual organic molecule

Efficient generation of near infra-red single photons from the zero-phonon line of a single molecule.

Using the zero-phonon line (ZPL) emission of a single molecule, we realized a triggered source of near-infra-red (lambda = 785 nm) single photons at a high repetition rate. A Weierstrass solid immersion lens is used to image single molecules with an optical resolution of 300 nm (approximately 0.4lambda) and a high collection efficiency. Because dephasing of the transition dipole due to phonons ...

The study of dose gamma rays of 192Ir source on DNA single strand break (SSB) and DNA double strand break (DSB) in soft tissue phantom

Introduction: Passage of ionizing radiation through the organs of living creatures develops clusters of damaged nucleotides inside the DNA rounds. 192Ir Gamma source is one of the most widely used sources in brachytherapy of cervical and prostate cancer. Thus, in this research, we investigated the flux of photons and its resulting secondary electrons, the single-strand break (S...

Single-Molecule Graphene Switches

A source of single photons that meets three important criteria for use in quantum-information systems has been unveiled in China by an international team of physicists. Based on a quantum dot, the device is an efficient source of photons that emerge as solo particles that are indistinguishable from each other. The researchers are now trying to use the source to create a quantum computer based o...

Interfering Heralded Single Photons from Two Separate Silicon Nanowires Pumped at Different Wavelengths

Practical quantum photonic applications require on-demand single photon sources. As one possible solution, active temporal and wavelength multiplexing has been proposed to build an on-demand single photon source. In this scheme, heralded single photons are generated from different pump wavelengths in many temporal modes. However, the indistinguishability of these heralded single photons has not...
