IntroductionThe pupillary light reflex (PLR) is the constriction of the pupil in response to light. The PLR in response to a pulse of light follows a complex waveform that can be characterized by several parameters. It is a sensitive marker of acute

Quantum interferometry suffers from residual distinguishability between input photons. Here, the authors show theoretically and experimentally, in a two-photon measurement, how to overcome this by manipulating additional degrees of freedom.

We analyze theoretically optimal operation of an optical key distribution (OKD) link based on fine intensity modulation of an optical signal transmitted over an attenuating channel to a direct detection receiver. With suitable digital postprocessing,

A method for photon-efficient quantum key distribution (QKD) is proposed and analyzed theoretically. The technique is based on nested encoding of multiple logical qubits into the discretized temporal degree of freedom of a single photon. The states o

Transmission of BPSK words optically decoded using a cascade of interferometric stages presents an alternative to current modulation standards for photon-starved communication, shifting the bulk of the system complexity to the receiver. Importantly,

We describe a modular design for an optical receiver implementing projective measurements on multiple logical qubits encoded in the temporal degree of freedom of a single photon. Application to satellite quantum key distribution is discussed.

The information capacity of an optical channel under power constraints is ultimately limited by the quantum nature of transmitted signals. We discuss currently available and emerging photonic technologies whose combination can be shown theoretically
