The separability of tripartite Gaussian state with amplification and amplitude damping
Xiao-yu Chen
Tripartite three mode Gaussian state undergoes parametric amplification and amplitude damping as well as thermal noise is studied. In the case of a state totally symmetrically inte…

Quantum capacity of lossy channel with additive classical Gaussian noise : a perturbation approach
Xiao-yu Chen
For a quantum channel of additive Gaussian noise with loss, in the general case of copies input, we show that up to first order perturbation, any non-Gaussian perturbation to t…

Perturbational approach to the quantum capacity of additive Gaussian quantum channel
Xiao-yu Chen
For a quantum channel with additive Gaussian quantum noise, at the large input energy side, we prove that the one shot capacity is achieved by the thermal noise state for all Gauss…
