Attaining classical capacity per unit cost of noisy bosonic Gaussian channels
Marcin Jarzyna
I show that classical capacity per unit cost of noisy bosonic Gaussian channels can be attained by employing generalized on-off keying modulation format and a projective measuremen…
Quantum Fingerprinting over AWGN Channels with Power-Limited Optical Signals
Michał Lipka, Marcin Jarzyna, Konrad Banaszek
Quantum fingerprinting reduces communication complexity of determination whether two -bit long inputs are equal or different in the simultaneous message passing model. Here we q…
Photon Efficiency Limits in the Presence of Background Noise
Konrad Banaszek, Wojciech Zwoliński, Ludwig Kunz +1
We identify theoretical limits on the photon information efficiency (PIE) of a deep-space optical communication link constrained by the average signal power and operated in the pre…
Low-cost limit of classical communication with restricted quantum measurements
Ludwig Kunz, Marcin Jarzyna, Wojciech Zwolinski +1
We consider a communication scenario where classical information is encoded in an ensemble of quantum states that admit a power series expansion in a cost parameter and with the va…
Approaching the ultimate capacity limit in deep-space optical communication
Konrad Banaszek, Ludwig Kunz, Marcin Jarzyna +1
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 emergi…
