چکیده
Abstract We present a systematic study of quantum receivers and modulation methods enabling resource efficient quantum-enhanced optical communication. introduce quantum-inspired schemes that theoretically yield better efficiency than legacy protocols. Experimentally, we demonstrate below the shot-noise limit symbol error rates for M ≤ 16 communication alphabets using software-configurable time-resolving receiver testbed. Further, experimentally verify our boost accuracy practical measurements significantly optimize combined use energy bandwidth are longer = 4 symbols.

Optimization of Energy Harvesting MISO Communication Channels
Optimization of a point-to-point (p2p) multipleinput single-output (MISO) communication system is considered when both the transmitter (TX) and the receiver (RX) have energy harvesting (EH) capabilities. The RX is interested in feeding back the channel state information (CSI) to the TX to help improve the transmission rate. The objective is to maximize the throughput by a deadline, subject to t...

Untappable communication channels over optical fibers from quantum-optical noise
Coherent light, as produced by lasers, gives rise to an intrinsic noise, known as quantum noise, optical noise or shot noise. AlphaEta is a protocol which exploits this physical phenomenon to obtain secure data encryption or key distribution over a fiber-optic channel in the presence of an eavesdropper. In this paper we focus on the cryptographic aspects of AlphaEta and its variants. Moreover, ...
