Quantifying non-Gaussianity of a quantum state by the negative entropy of quadrature distributions
Jiyong Park, Jaehak Lee, Kyunghyun Baek +1
We propose a non-Gaussianity measure of a multimode quantum state based on the negentropy of quadrature distributions. Our measure satisfies desirable properties as a non-Gaussiani…
Fundamental limits on concentrating and preserving tensorized quantum resources
Jaehak Lee, Kyunghyun Baek, Jiyong Park +2
Quantum technology offers great advantages in many applications by exploiting quantum resources like nonclassicality, coherence, and entanglement. In practice, an environmental noi…
Average fidelity and fidelity deviation in noisy quantum teleportation
WooYeong Song, Junghee Ryu, Kyunghyun Baek +1
We analyze the average fidelity (say, F) and the fidelity deviation (say, D) in noisy-channel quantum teleportation. Here, F represents how well teleportation is performed on avera…
