Classification of informative subsets in quantum encrypted cloning on qudits
Chen-Ming Bai, Xin-Liang Zhou, Yu Luo
Encrypted cloning offers a means of introducing redundancy into quantum storage while respecting the no-cloning theorem: an unknown state is encoded into multiple signal-noise pair…
Quantum limits on squeezing
Xin Zhou, Francesco Massel
In our work, we show how, for a network of bosonic modes, canonical commutation relations constrain the coefficients relating input and internal modes. Based on these constraints,…
Nonreciprocal Entanglement by Dynamically Encircling a Nexus
Lei Huang, Peng-Fei Wang, Jian-Qi Zhang +5
Nonreciprocal entanglement, characterized by inherently robust operation, is a cornerstone for quantum information processing and communications. However, it remains a great challe…
Symmetry resolved entanglement entropy after an inhomogeneous quench
Hui-Huang Chen, Xin-Liang Zhou, Jiayu Yin +1
We investigate the non-equilibrium time evolution of symmetry-resolved entanglement entropy (SREE) following an inhomogeneous quench in a critical one-dimensional free fermion syst…
