Dynamical one-from-many quantum metrology: Sum rule and matrix-free precision bound
Ziyu Xie, Junjie Liu
Practical quantum single-parameter estimation is rarely a pristine task; it almost invariably involves nuisance parameters, casting it as a one-from-many problem. Existing approach…
Coherent electric field manipulation of nuclear spin qudit
Sumin Lim, Mikhail V. Vaganov, Niccolo Fontana +2
Spins in condensed matter, especially well-isolated nuclear spins, offer attractive quantum degrees of freedom for computing, sensing, and networking because of their long coherenc…
Initial-state-dependent dephasing effect in non-Hermitian Su-Schrieffer-Heeger models
Tao Min, Junjie Liu
Understanding the dynamical evolution of non-Hermitian systems under external dissipation is essential for devising realistic non-Hermitian quantum devices that surpass the capabil…
Direct temperature readout in nonequilibrium quantum thermometry
Yan Xie, Junjie Liu
Quantum thermometry aims to measure temperature in nanoscale quantum systems, paralleling classical thermometry. However, temperature is not a quantum observable, and most theoreti…
