Control incompatibility in multiparameter quantum metrology
Zhiyao Hu, Shilin Wang, Linmu Qiao +6
In practical applications like quantum sensing and quantum imaging, there is often a necessity to estimate multiple parameters simultaneously. Although the ultimate precision limit…
Optimal Quantum Purity Amplification
Zhaoyi Li, Honghao Fu, Takuya Isogawa +2
Quantum purity amplification (QPA) provides a novel approach to counteracting the pervasive noise that degrades quantum states. We present the optimal QPA protocol for general quan…
Interferometry of quantum correlation functions to access quasiprobability distribution of work
Santiago Hernández-Gómez, Takuya Isogawa, Alessio Belenchia +4
The Kirkwood-Dirac quasiprobability distribution, intimately connected with the quantum correlation function of two observables measured at distinct times, is becoming increasingly…
