One photon per bit communication for free-space optical links
Paper in proceeding, 2020

We demonstrate a free-space transmission experiment showing bit-error-free, 'black-box' sensitivity of 1 photon-per-information-bit (PPB) at a net information rate of 10.5 Gb/s. The system uses a simple modulation format (QPSK) transmitter and near noiseless phase sensitive pre-amplified coherent receiver.
