Enhancing Phase Retrievability of Quantum Channels via Interferometric Coupling
Kai Liu, Deguang Han, Omar Nour
Phase retrievability of a quantum channel asks whether pure states can be reconstructed from suitable measurements. In this paper, we study this problem from three complementary vi…

Fidelity preserving and decoherence for mixed unitary quantum channels
Kai Liu, Deguang Han
Distinguishable and non-distinguishable quantum states are fundamental resources in quantum mechanics and quantum technologies. Interactions with the environment often induce decoh…
