Detecting basis-dependent hardware errors through spatio-temporal quantum steering
Hsiang-Wei Huang, Kuo-Feng Chiu, Yi-Te Huang +3
Spatio-temporal quantum steering provides a framework for benchmarking the nonclassicality of general quantum state transfer processes. A central diagnostic is the no-signaling-in-…
Experimental simulation of postselected closed timelike curves for decoding scrambled quantum information
Yi-Te Huang, Hsiang-Wei Huang, Jhen-Dong Lin +5
Quantum information scrambling (QIS) describes the rapid spread of initially localized information across an entire quantum many-body system through entanglement generation. Once s…
RC-HEOM Hybrid Method for Non-Perturbative Open System Dynamics
Po-Rong Lai, Jhen-Dong Lin, Yi-Te Huang +3
The Hierarchical equations of motion (HEOM) method is an important non-perturbative technique, allowing numerically exact treatment of open quantum systems with strong coupling and…
Charging efficiency bursts in a quantum battery with cyclic indefinite causal order
Po-Rong Lai, Hsien-Chao Jan, Jhen-Dong Lin +1
Enhancement of quantum battery performance is a popular subject in quantum thermodynamics. An interesting phenomenon is the quick charging effect [Phys. Rev. Res. 6, 023136 (2024)]…
A General Class of Functionals for Certifying Quantum Incompatibility
Kuan-Yi Lee, Jhen-Dong Lin, Adam Miranowicz +1
Quantum steering, measurement incompatibility, and instrument incompatibility have recently been recognized as unified manifestations of quantum incompatibility. Building on this p…
Resource efficient certification of system environment entanglement solely from reduced system dynamics
Jhen-Dong Lin, Pao-Wen Tu, Kuan-Yi Lee +4
Certifying nonclassical correlations typically requires access to all subsystems, presenting a major challenge in open quantum systems coupled to inaccessible environments. Recent…
