Action formalism for geometric phases from self-closing quantum trajectories

D Shea, A Romito - Journal of Physics A: Mathematical and …, 2024 - iopscience.iop.org
When subject to measurements, quantum systems evolve along stochastic quantum
trajectories that can be naturally equipped with a geometric phase observable via a post …

Eluding Zeno effect via dephasing and detuning

J Cuadrado, A Luis - Physica Scripta, 2024 - iopscience.iop.org
We analyze some variants of the Zeno effect in which the frequent observation of the
population of an intermediate state does not prevent the transition of the system from the …

Hamiltonian simulation in Zeno subspaces

KR Dizaji, A Haqq, AB Magann, C Arenz - arXiv preprint arXiv:2405.13589, 2024 - arxiv.org
We investigate the quantum Zeno effect as a framework for designing and analyzing
quantum algorithms for Hamiltonian simulation. We show that frequent projective …

Higher order weak values for paths in nested Mach-Zender interferometers

S Chowdhury, JB Götte - arXiv preprint arXiv:2407.06989, 2024 - arxiv.org
We consider weak values in the Feynman propagator framework, to gain a broader
understanding of their interpretation in terms of path integrals. In particular, we examine the …

Fundamental Investigations of Quantum and Bandlimited Systems

T Karmakar - 2024 - search.proquest.com
We look at three different kinds of systems, requiring quantum to classical description. The
first system is a quantum harmonic oscillator in general Gaussian states undergoing …
