Optimizing Strongly Interacting Fermionic Hamiltonians
Matthew B. Hastings, Ryan O'Donnell
The fundamental problem in much of physics and quantum chemistry is to optimize a low-degree polynomial in certain anticommuting variables. Being a quantum mechanical problem, in m…
Pauli error estimation via Population Recovery
Steven T. Flammia, Ryan O'Donnell
Motivated by estimation of quantum noise models, we study the problem of learning a Pauli channel, or more generally the Pauli error rates of an arbitrary channel. By employing a n…
The Quantum Union Bound made easy
Ryan O'Donnell, Ramgopal Venkateswaran
We give a short proof of Gao's Quantum Union Bound and Gentle Sequential Measurement theorems.
Toward Instance-Optimal State Certification With Incoherent Measurements
Sitan Chen, Jerry Li, Ryan O'Donnell
We revisit the basic problem of quantum state certification: given copies of unknown mixed state and the description of a mixed state , decide wheth…
