Triggering Many Molecular Reactions With a Single Photon,Quantum Information for Molecular Physics

E n e r g y l a n d s c a pe that governs the chemical reaction of two molecules after the system absorbs one single photon. At the first reaction step t0 the system consists of five molecules strongly interacting with the electromagnetic vacuum. At the second reaction step t1 the system has evolved and one molecule has isomerized. In the strong coupling regime this process continues with more ...

Distortions from Multi-photon Triggering in a Single CMOS SPAD

Motivated by the need for correct characterization and operation of single-photon avalanche diodes (SPADs), three methods for discriminating between singleand multi-photon triggering in a single CMOS SPAD are compared. The first method, utilizing a measurement of the avalanche’s quench time, correctly distinguishes between avalanches initiated by one photon or 100 incident photons with p > 0.80...

Coherent Transport of Single Photon in a Quantum Super-cavity with Mirrors Composed of Λ-Type Three-level Atomic Ensembles

In this paper, we study the coherent transport of single photon in a coupled resonator waveguide (CRW) where two threelevel Λ-type atomic ensembles are embedded in two separate cavities. We show that it is possible to control the photon transmission and reflection coefficients by using classical control fields. In particular, we find that the total photon transmission and reflection are achieva...

Detection of Ultraweak Photon Emission (UPE) from Cells as a Tool for Pathological Studies

Objective: It is well-known that all living cells emit ultra-weak photon emission (UPE), which is due to byproducts of chemical reactions in cell metabolisms. It has been shown that Reactive Oxygen Species (ROS) in the cells enhances the UPE intensity. The magnitude of such UPE is extremely weak (i.e. a few to 103 photons/ (sec.cm2)), and the detection of such ultra-weak signals is hardly possi...
