Bayesian Quantum Amplitude Estimation
Alexandra Ramôa, Luis Paulo Santos
We present BAE, a problem-tailored and noise-aware Bayesian algorithm for quantum amplitude estimation. In a fault tolerant scenario, BAE is capable of saturating the Heisenberg li…

Low Cost Bayesian Experimental Design for Quantum Frequency Estimation with Decoherence
Alexandra Ramôa, LuÃs Paulo Santos, Akihito Soeda
A two-level quantum system evolving under a time-independent Hamiltonian produces oscillatory measurement probabilities. The estimation of the associated frequency is a cornerstone…
