Numerical methods for the simulation of quantum walks and quantum annealing
Asa Hopkins, Viv Kendon
It is known that Chebyshev based polynomial approximation gives a near-optimal rate of convergence for calculating a function of a Hermitian matrix. However, previous work has not…
Heuristics for multi-stage quantum walks to find Ising ground states
Asa Hopkins, Viv Kendon
One way to approximate a quantum annealing schedule is to use multiple quantum walks chained together, without intermediate measurements, to produce a multi-stage quantum walk (MSQ…
Quantum filter reduction for measurement-feedback control via unsupervised manifold learning
Anne E. B. Nielsen, Asa S. Hopkins, Hideo Mabuchi
We derive simple models for the dynamics of a single atom coupled to a cavity field mode in the absorptive bistable parameter regime by projecting the time evolution of the state o…
Nonlinear Quantum Dynamics
Salman Habib, Tanmoy Bhattacharya, Andrew Doherty +8
The vast majority of the literature dealing with quantum dynamics is concerned with linear evolution of the wave function or the density matrix. A complete dynamical description re…
Proposed magneto-electrostatic ring trap for neutral atoms
Asa Hopkins, Benjamin Lev, Hideo Mabuchi
We propose a novel trap for confining cold neutral atoms in a microscopic ring using a magneto-electrostatic potential. The trapping potential is derived from a combination of a re…
Feedback cooling of a nanomechanical resonator
Asa Hopkins, Kurt Jacobs, Salman Habib +1
Cooled, low-loss nanomechanical resonators offer the prospect of directly observing the quantum dynamics of mesoscopic systems. However, the present state of the art requires cooli…
