Exponential entanglement advantage in sensing correlated noise
Yu-Xin Wang, Jacob Bringewatt, Alireza Seif +3
Correlated noise naturally arises in quantum systems due to, e.g., phase and amplitude fluctuations in global control or long-range correlations generated by a many-body sensing ta…
Generalized geometric speed limits for quantum observables
Jacob Bringewatt, Zach Steffen, Martin A. Ritter +6
Leveraging quantum information geometry, we derive generalized quantum speed limits on the rate of change of the expectation values of observables. These bounds subsume and, for Hi…
Resilience-Runtime Tradeoff Relations for Quantum Algorithms
Luis Pedro García-Pintos, Tom O'Leary, Tanmoy Biswas +4
A leading approach to algorithm design aims to minimize the number of operations in an algorithm's compilation. One intuitively expects that reducing the number of operations may d…
Estimation of Hamiltonian parameters from thermal states
Luis Pedro García-Pintos, Kishor Bharti, Jacob Bringewatt +4
We upper- and lower-bound the optimal precision with which one can estimate an unknown Hamiltonian parameter via measurements of Gibbs thermal states with a known temperature. The…
Optimal function estimation with photonic quantum sensor networks
Jacob Bringewatt, Adam Ehrenberg, Tarushii Goel +1
The problem of optimally measuring an analytic function of unknown local parameters each linearly coupled to a qubit sensor is well understood, with applications ranging from field…
