Maximal Fisher Budget Forces Blind Directions in Bipartite Collective SU(d) Metrology
Tariq Aziz, Naeem Akhtar, Dong Wang +1
For pure two-qudit probes used in a single fixed setting to estimate a common SU(d) transformation, maximal total Fisher sensitivity and full local identifiability are mutually exc…
Finer sub-Planck structures and displacement sensitivity of SU(1,1) circular states
Naeem Akhtar, Jia-Xin Peng, Tariq Aziz +2
Quantum states with sub-Planck features exhibit sensitivity to phase-space displacements beyond the standard quantum limit, making them useful for quantum metrology. In the context…
Entropic Diagram Characterization of Quantum Coherence: Degenerate Distillation and the Maximum Eigenvalue Uncertainty Bound
Tariq Aziz, Meng-Long Song, Liu Ye +1
We develop a rigorous framework for quantifying quantum coherence in finite-dimensional systems by applying the Schur-Horn majorization theorem to relate eigenvalue distributions a…
Spectral Bounds on Entropy and Ergotropy via Statistical Effective Temperature in Classical Polarization and Quantum Thermal States
Tariq Aziz, Meng-Long Song, Liu Ye +3
We formulate a unified definition of the statistical effective temperature (SET) for finite-dimensional classical and quantum systems using dimension-dependent indices of purity de…
