Entanglement certification via causal-order interferometry in a quantum switch
Haojie Wang, Shuheng Liu, Qiongyi He
Entanglement certification is often performed on states that have already undergone noisy transmission or processing. Noise can reduce the surviving entanglement and can also cause…
Qutrit entanglement and joint multi-parameter estimation in an optical clock platform
Ohad Lib, Shuheng Liu, Maximilian Ammenwerth +7
Quantum metrology harnesses entanglement to improve measurement precision beyond classical limits. While standard protocols rely on two-level qubits to estimate a single parameter,…
From Spectral Singularities to Multipartite Entanglement Scaling at Higher-Order Exceptional Points
Chunlai Yang, Shuheng Liu, Xinyao Huang +2
Exceptional points (EPs) are non-Hermitian spectral singularities exhibiting fractional-power responses, yet their implications for multipartite entanglement of interacting quantum…
Distributed quantum sensing with measurement-after-interaction strategies
Jiajie Guo, Shuheng Liu, Matteo Fadel +1
We investigate multiparameter quantum estimation protocols based on measurement-after-interaction (MAI) strategies, in which the probe state undergoes an additional evolution prior…
