Inverse-squeezing receivers for squeezed-state pulse-position modulation under ideal and phase-diffusion conditions
Enhao Bai, Fengkai Sun, Tianyi Wu +4
We introduce a squeezed-state pulse-position modulation (S-PPM) format, where the empty slots are squeezed vacuum states and the pulse slot is a displaced squeezed state. Based on…

Residual-Squeezing Mechanism of Mismatch in Inverse-Squeezing Kennedy Receivers
Enhao Bai, Fengkai Sun, Tianyi Wu +8
The discrimination of quantum states is fundamental to quantum information processing. Inverse-squeezing Kennedy (IS-Kennedy) receivers can outperform the coherent-state BPSK Helst…

Near-optimal discrimination of displaced squeezed binary signals using displacement, inverse-squeezing, and photon-number-resolving detection
Enhao bai, Jian Peng, Tianyi Wu +6
We propose an inverse-squeezing Kennedy receiver for discriminating binary phase-shift-keyed displaced squeezed vacuum states. The receiver combines a Kennedy-type nulling displace…
