Time Independence Does Not Limit Information Flow. II. The Case with Ancillas
T. C. Mooney, Dong Yuan, Adam Ehrenberg +3
While the impact of locality restrictions on quantum dynamics and algorithmic complexity has been well studied in the general case of time-dependent Hamiltonians, the capabilities…
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…
Projective toric designs, quantum state designs, and mutually unbiased bases
Joseph T. Iosue, T. C. Mooney, Adam Ehrenberg +1
Toric -designs, or equivalently -designs on the diagonal subgroup of the unitary group, are sets of points on the torus over which sums reproduce integrals of degree mono…
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…
