Evaluation of the quantum Fisher information for large systems via an ancilla
Qi Liu, Xin-Yu Hao, Jing Liu
Quantum Fisher information (QFI) is a fundamental quantity in quantum information and quantum mechanics, and evaluating it in various physical systems has become an important resea…
Impacts of isolated nucleon-nucleon correlations in relativistic O+O collisions
Qi Liu, Hadi Mehrabpour, Bing-Nan Lu
Nucleon-nucleon (NN) correlations in nuclear ground states can leave measurable imprints on the initial geometry of relativistic light-ion collisions. We introduce an Acceptance-Re…
Quantum-amplified global-phase spectroscopy on an optical clock transition
Leon Zaporski, Qi Liu, Gustavo Velez +5
Optical lattice clocks (OLCs) are at the forefront of precision metrology, operating near a standard quantum limit (SQL) set by quantum noise. Harnessing quantum entanglement offer…
Enhancing Dynamic Range of Sub-Quantum-Limit Measurements via Quantum Deamplification
Qi Liu, Ming Xue, Matthew Radzihovsky +4
Balancing high sensitivity with a broad dynamic range is a fundamental challenge in measurement science, as improving one often compromises the other. While traditional quantum met…
Evaluation of quantum Fisher information for large system
Qi Liu
Quantum Fisher information (QFI) plays a vital role in quantum precision measurement, quantum information, many-body physics, and other domains. Obtaining the QFI from experiment f…
