Saturating the one-axis twisting quantum Cramér-Rao bound with a total spin readout
T. J. Volkoff, Michael J. Martin
We show that the lowest quantum Cramér-Rao bound achievable in interferometry with a one-axis twisted spin coherent state is saturated by the asymptotic method of moments error of…
Asymptotic optimality of twist-untwist protocols for Heisenberg scaling in atomic interferometry
T. J. Volkoff, Michael J. Martin
Twist-untwist protocols for quantum metrology consist of a serial application of: 1. unitary nonlinear dynamics (e.g., spin squeezing or Kerr nonlinearity), 2. parameterized dynami…
Large gradients via correlation in random parameterized quantum circuits
Tyler Volkoff, Patrick J. Coles
Scaling of variational quantum algorithms to large problem sizes requires efficient optimization of random parameterized quantum circuits. For such circuits with uncorrelated param…
Spatial distribution of superfluidity and superfluid distillation of Bose liquids
T. J. Volkoff, Yongkyung Kwon
Under the assumption of two fluid kinematics of a nonrelativistic Bose liquid in the presence of a local velocity field , local Galilei transformations are used to derive for…
Path integral Monte Carlo simulation of global and local superfluidity in liquid He reservoirs separated by nanoscale apertures
Tyler Volkoff, Yongkyung Kwon, K. Birgitta Whaley
We present a path integral Monte Carlo study of the global superfluid fraction and local superfluid density in cylindrically-symmetric reservoirs of liquid He separated by na…
