Highly efficient single photon detecto rs are ubiquitous in quantum optics and atomic physics. However\, many of the theories of single photon detection still arise from the Glauber theor y of photodetection which was primarily developed for inefficient detector s (weak light-matter coupling). The first goal of the talk is to contrast the photon counting mechanism in photomultiplier tubes (PMTs)\, single pho ton avalanche diodes (SPADs)\, single electron transistor based photodetec tors (SET-PDs) and superconducting nanowire single photon detectors (SNSPD s). This can help develop a general model for single photon detection beyo nd Glauber'\;s theory. \;
\n\nSecondly\, we will present exp erimental results on time-correlated single photon counting experiments th at demonstrate long range dipole-dipole interactions between quantum emitt ers mediated by metamaterials.  \; We will discuss a fundamental limit to the efficiency of energy transfer between quantum emitters and discuss routes to achieve this limit through induced coherence. Our approach to e ngineering dipole-dipole interactions can motivate experiments from atomic systems (eg: Rydberg blockade) to biochemistry (Forster/Dexter resonance energy transfer).
