Optimizing Variational Quantum Algorithms using Pontryagin's Minimum Principle
Zhi-Cheng Yang, Armin Rahmani, Alireza Shabani +2
We use Pontryagin's minimum principle to optimize variational quantum algorithms. We show that for a fixed computation time, the optimal evolution has a bang-bang (square pulse) fo…
Minimizing irreversible losses in quantum systems by local counter-diabatic driving
Dries Sels, Anatoli Polkovnikov
Counter-diabatic driving protocols were proposed as a means to do fast changes in the Hamiltonian without exciting transitions. Such driving in principle allows one to realize arbi…
Group transformations and entangled-state quantum gates with directionally unbiased linear-optical multiports
David S. Simon, Casey A. Fitzpatrick, Alexander V. Sergienko
The concept of directionally unbiased optical multiports is introduced, in which photons may reflect back out the input direction. A linear-optical implementation is described, and…
Multiple-scale integro-differential perturbation method for generic non-Markovian environments
Xiangyi Meng, Yang Li, Jian-Wei Zhang +2
Non-Markovianity may significantly speed up quantum dynamics when the system interacts strongly with an infinite large reservoir, of which the coupling spectrum should be fine-tune…
Quantum statistical gravity: time dilation due to local information in many-body quantum systems
Dries Sels, Michiel Wouters
We propose a generic mechanism for the emergence of a gravitational potential that acts on all classical objects in a quantum system. Our conjecture is based on the analysis of mut…
Non-Abelian Aharonov-Bohm effect with the time-dependent gauge fields
Seyed Ali Hosseini Mansoori, Behrouz Mirza
We investigate the non-Abelian Aharonov-Bohm (AB) effect for time-dependent gauge fields. We prove that the non-Abelian AB phase shift related to time-dependent gauge fields, in wh…
A Precessing Ferromagnetic Needle Magnetometer
Derek F. Jackson Kimball, Alexander O. Sushkov, Dmitry Budker
A ferromagnetic needle is predicted to precess about the magnetic field axis at a Larmor frequency under conditions where its intrinsic spin dominates over its rotational angul…
Ergodic dynamics and thermalization in an isolated quantum system
C. Neill, P. Roushan, M. Fang +19
Statistical mechanics is founded on the assumption that all accessible configurations of a system are equally likely. This requires dynamics that explore all states over time, know…
Grover Walks on a Line with Absorbing Boundaries
Kun Wang, Nan Wu, Parker Kuklinski +3
In this paper, we study Grover walks on a line with one and two absorbing boundaries. In particular, we present some results for the absorbing probabilities both in a semi-finite a…
