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…
The Second Moment of Hafnians in Gaussian Boson Sampling
Adam Ehrenberg, Joseph T. Iosue, Abhinav Deshpande +2
Gaussian Boson Sampling is a popular method for experimental demonstrations of quantum advantage, but many subtleties remain in fully understanding its theoretical underpinnings. A…
Average Rényi Entanglement Entropy in Gaussian Boson Sampling
Jason Youm, Joseph T. Iosue, Adam Ehrenberg +2
Recently, many experiments have been conducted with the goal of demonstrating a quantum advantage over classical computation. One popular framework for these experiments is Gaussia…
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…
