Fidelity and Fisher information on quantum channels
2015 · arXiv (Cornell University)
The fidelity function of quantum states have been widely used in quantum information science and frequently arises in the quantification of optimal performances for the estimation and distinguish of quantum states. A fidelity function on …

Optimally controlled quantum discrimination and estimation
2020 · Physical Review Research
This work shows how to improve distinguishability between two qubit states and stabilize the maximally achievable distinguishability for times longer than the typical decay time by replacing the Ramsey protocol by one employing temporally shaped …

Quantum hypothesis testing via robust quantum control
2023 · arXiv (Cornell University)
Quantum hypothesis testing plays a pivotal role in quantum technologies, making decisions or drawing conclusions about quantum systems based on observed data. Recently, quantum control techniques have been successfully applied to quantum hypothesis testing, enabling …
