Quantum Hamiltonian Learning Using Imperfect Quantum Resources
Nathan Wiebe, Christopher Granade, Christopher Ferrie +1
Identifying an accurate model for the dynamics of a quantum system is a vexing problem that underlies a range of problems in experimental physics and quantum information theory. Re…
High posterior density ellipsoids of quantum states
Christopher Ferrie
Regions of quantum states generalize the classical notion of error bars. High posterior density (HPD) credible regions are the most powerful of region estimators. However, they are…
Hamiltonian Learning and Certification Using Quantum Resources
Nathan Wiebe, Christopher Granade, Christopher Ferrie +1
In recent years quantum simulation has made great strides culminating in experiments that operate in a regime that existing supercomputers cannot easily simulate. Although this rai…
Quantum limits on post-selected, probabilistic quantum metrology
Joshua Combes, Christopher Ferrie, Zhang Jiang +1
Probabilistic metrology attempts to improve parameter estimation by occasionally reporting an excellent estimate and the rest of the time either guessing or doing nothing at all. H…
Weak value amplification is suboptimal for estimation and detection
Christopher Ferrie, Joshua Combes
We show using statistically rigorous arguments that the technique of weak value amplification (WVA) does not perform better than standard statistical techniques for the tasks of si…
Likelihood-free methods for quantum parameter estimation
Christopher Ferrie, Christopher E. Granade
In this Letter, we strengthen and extend the connection between simulation and estimation to exploit simulation routines that do not exactly compute the probability of experimental…
