Quantum amplification and purification of noisy coherent states
2017 · Physical Review A
Quantum-limited amplifiers increase the amplitude of quantum signals at the price of introducing additional noise. Quantum purification protocols operate in the reverse way, by reducing the noise while attenuating the signal. Here we investigate a …

Quantum communication through devices with indefinite input-output direction
2022 · arXiv (Cornell University)
Certain quantum devices, such as half-wave plates and quarter-wave plates in quantum optics, are bidirectional, meaning that the roles of their input and output ports can be exchanged. Bidirectional devices can be used in a …
