Beyond the Positive Partial Transpose Squared Conjecture: The Qutrit Case
Junhyeong An, Soojoon Lee
Entanglement swapping is a fundamental operation in quantum repeaters for establishing entanglement between distant parties. The positive partial transpose (PPT) squared conjecture…
Extreme volume monogamy via bound-state engineering
Wen-Jie Zhang, Jun-Hong An
Quantum steering ellipsoid (QSE) provides a faithful representation of a two-qubit state. When extended to tripartite systems, the steerability from a trusted party to different re…
Strongly coupled giant-atom waveguide quantum electrodynamics
Zong-Wei Wu, Jun-Hong An
Describing systems of superconducting atoms coupled to a continuum of photonic modes at multiple separated locations in a waveguide, waveguide quantum electrodynamics (QED) with gi…
Protecting spin squeezing from decoherence
Lin Jiao, Han Pu, Jun-Hong An
As a crucial resource in the field of quantum metrology, spin squeezing can facilitate highly precise measurements that surpass the limitations imposed by classical physics. Howeve…
Noise-Resilient Quantum Reinforcement Learning
Jing-Ci Yue, Jun-Hong An
As a branch of quantum machine learning, quantum reinforcement learning (QRL) aims to solve complex sequential decision-making problems more efficiently and effectively than its cl…
Maximal extension on converse monogamy of entanglement for tripartite pure states
Junhyeong An, Soojoon Lee
Unlike classical correlations, entanglement cannot be freely shared among multiple parties. This unique feature of quantum systems is known as the monogamy of entanglement. While i…
