Abstract: Current experimental efforts to test the fundamental CPT symmetry with single (anti-)protons are progressing at a rapid pace but are hurt by the nonzero temperature of particles and the difficulty of spin state detection. We describe a laser-based and quantum logic inspired approach to single (anti-)proton cooling and state detection.

We investigate the probabilities of detecting single- and multi-photon coherent states on InGaAs/InP sine-gated and free-run avalanche diodes. We conclude that multi-photon state detection cannot be regarded as independent events of absorption of individual single-photon states.

Single photon randomness originating from the symmetry of dipole emission and the unpredictability of spontaneous emission [55.41644538483948]
Quantum random number generation is a key ingredient for quantum cryptography and fundamental quantum optics. We experimentally demonstrate quantum random number generation based on the spontaneous emission process. The scheme can be extended to random number generation by coherent single photons with potential applications in solid-state based quantum communication at room temperature.

This enables reduction of the dynamics to that of a simple, cavity-damped Tavis-Cummings model with the collective spin determined by the total angular momentum of the ground hyperfine level.
