Extended analysis of distillation and purification of squeezed states of light

Year: 2025

Type: article

Abstract: Previously, the authors experimentally used two-photon subtraction to achieve distillation of single-mode optical squeezed states. Here, they present an extended theoretical study of distillation and purification of such states by conditional photon subtraction. They find parallels between their squeezing distillation scheme and recent schemes for the generation of approximate GKP states in fault-tolerant quantum computing.
