Bidirectional coherent classical communication [PDF]
Quantum Information and Computation, 2005 A unitary interaction coupling two parties enables quantum or classical communication in both the forward and backward directions. Each communication capacity can be thought of as a tradeoff between the achievable rates of specific types of forward and backward communication.

Time Reverse Equalization Algorithm for 16 QAM Coherent Optical Communication Systems
IEEE Access, 2021 The high speed rotation of state of polarization (RSOP) is a key issue for 16 quadrature amplitude modulation (QAM) coherent optical polarization division multiplexing (PDM) communication systems in strong lightning weather. To reduce the bit error rate (

Quantum communication with coherent states of light [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2017 Quantum communication offers long-term security especially, but not only, relevant to government and industrial users. It is worth noting that, for the first time in the history of cryptographic encoding, we are currently in the situation that secure communication can be based on the fundamental laws of physics (information theoretical security) rather

A New Perspective on Assessing Cognition in Children through Estimating Shared Intentionality
Journal of Intelligence, 2022 This theoretical article aims to create a conceptual framework for future research on digital methods for assessing cognition in children through estimating shared intentionality, different from assessing through behavioral markers.

IEEE Photonics Journal, 2021 We propose a cascaded neural network (NN) to simultaneously identify the modulation formats and monitor the optical-signal-to-noise ratio (OSNR). In the second-level network, it is a single deep NN (DNN) rather than multiple sub-networks, which makes the

IEEE Photonics Journal, 2022 The traditional fast Fourier transform based frequency offset estimation (FFT-FOE) estimates the frequency offset by searching the spectral peak of the signal after the fourth power operation, which is suitable for multiple modulation formats.

Coherent communication with linear optics [PDF]
Physical Review A, 2008 We show how to implement several continuous-variable coherent protocols with linear optics. Noise can accumulate when implementing each coherent protocol with realistic optical devices. Our analysis bounds the level of noise accumulation. We highlight the connection between a coherent channel and a nonlocal quantum nondemolition interaction and give ...
