High efficiency photon counting using stopped light [PDF]
Physical Review Letters, 2002 Single-photon detection and photon counting play a central role in a large number of quantum communication and computation protocols. While the efficiency of state-of-the-art photo-detectors is well below the desired limits, quantum state measurements in

Efficient Counting with Optimal Resilience [PDF]
SIAM Journal on Computing, 2017 Consider a complete communication network of $n$ nodes, where the nodes receive a common clock pulse. We study the synchronous $c$-counting problem: given any starting state and up to $f$ faulty nodes with arbitrary behaviour, the task is to eventually have all correct nodes labeling the pulses with increasing values modulo $c$ in agreement.

The dependence of Ge detectors efficiency on the density of the samples in gamma-ray spectrometry [PDF]
Nuclear Technology and Radiation Protection, 2007 The effect of the density of environmental samples on the counting efficiency of Ge detectors used in gamma-spectrometry was studied. The dependence εff(ρ) was determined for two HPGe detectors (relative efficiencies 18% and 20%) using five radioactive ...
