Probing coherence and noise tolerance in discrete-time quantum walks: unveiling self-focusing and breathing dynamics
A. R. C. Buarque, W. S. Dias
The sensitivity of quantum systems to external disturbances is a fundamental problem for the implementation of functional quantum devices, quantum information and computation. Base…
Bloch-like super-oscillations and unidirectional motion of phase driven quantum walkers
A. R. C. Buarque, M. L. Lyra, W. S. Dias
We study the dynamics of a quantum walker simultaneously subjected to time-independent and -dependent phases. Such dynamics emulates a charged quantum particle in a lattice subject…
Self-trapped quantum walks
A. R. C. Buarque, W. S. Dias
We study the existence and charaterization of self-trapping phenomena in discrete-time quantum walks. By considering a Kerr-like nonlinearity, we associate an acquisition of the in…
Aperiodic space-inhomogeneous quantum walks: localization properties, energy spectra and enhancement of entanglement
A. R. C. Buarque, W. S. Dias
We study the localization properties, energy spectra and coin-position entanglement of the aperiodic discrete-time quantum walks. The aperiodicity is described by spatially depende…
