Quantum linear amplifier enhanced by photon subtraction and addition
Ho-Joon Kim, Su-Yong Lee, Se-Wan Ji +1
A deterministic quantum amplifier inevitably adds noise to an amplified signal due to the uncertainty principle in quantum physics. We here investigate how a quantum-noise-limited…

Efficient entanglement criteria beyond Gaussian limits using Gaussian measurements
Hyunchul Nha, Su-Yong Lee, Se-Wan Ji +1
We present a formalism to derive entanglement criteria beyond the Gaussian regime that can be readily tested by only homodyne detection. The measured observable is the Einstein-Pod…
