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…
Beating the Standard Quantum Limit for Binary Constellations in the Presence of Phase Noise
L. Kunz, M. T. DiMario, F. E. Becerra +1
Unconventional receivers enable reduction of error rates in optical communication systems below the standard quantum limit (SQL) by implementing discrimination strategies for const…
Optimized communication strategies with binary coherent states over phase noise channels
M. T. DiMario, L. Kunz, K Banaszek +1
The achievable rate of information transfer in optical communications is determined by the physical properties of the communication channel, such as the intrinsic channel noise. Bo…
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…
