Quantum Walk Echoes

Abstract

Time-reversal coherent dynamics like spin echo was observed in a simple continuous-time quantum walk system. The probability distribution of a quantum walker, which spreads proportionally to the time t, can be refocused at t = 2t1 by switching the phases of the walker’s wave function at t = t1.

Quantum Echoes and revivals in two-band systems and Bose-Einstein condensates

Phillipp Reck

In this thesis, we address the long-standing question of time-reversal protocols for the quantum mechanical wave function for continuous degrees of freedom. We propose two new mechanisms - quantum time mirrors - one for two-band systems, the other one for systems described by the nonlinear Schrödinger equation like Bose-Einstein condensates. In both cases, a homogeneous pulse is applied to the system that is supposed to flip the velocity direction and thus invert the motion of the system. In a two-band system, the pulse induces a transition from one band to the other. For bands with opposite group velocity directions, e.g. Dirac cone systems like graphene, the band-transition directly leads to an inversion of the motion. By generalizing the results for arbitrary bands and additionally investigating the effects of perturbations like disorder or electro-magnetic fields, we are able to determine for any (effective) two-band system at hand with a given pulse whether it is a suited candidate for the quantum time mirror. In the Bose-Einstein condensates, the inversion of motion is achieved by quickly varying the nonlinear term. The phases in the wave function acquired during the pulse affect the velocity and for certain parameters it switches sign. Although echoes are induced by this mechanism, the fidelity is rather low. However, time lenses, i.e. refocusing the wave packet by a time-dependent pulse, can be achieved with high fidelity in this setup. Even solitary waves can be created whose refocus fidelity stay above 99% for more than 100,000 pulses. In the last part of the thesis, we investigate zitterbewegung in two-band systems with time-dependent potentials. In the driven setup, we find persistent, i.e. undamped, modes of the zitterbewegung that would decay for a wave packet in a static environment. Moreover, using the quantum time mirror pulses described above, echoes of the zitterbewegung can be achieved that are in some sense similar to the well-known and highly exploited spin echo.

Relativistic quantum walks

Frederick W. Strauch

By pursuing the deep relation between the one-dimensional Dirac equation and quantum walks, the physical role of quantum interference in the latter is explained. It is shown that the time evolution of the probability density of a quantum walker, initially localized on a lattice, is directly analogous to relativistic wave-packet spreading. Analytic wave-packet solutions reveal a striking connection between the discrete and continuous-time quantum walks.

Quantum Reversibility: Is there an Echo?

Moritz Hiller, Tsampikos Kottos, Doron Cohen +1 more

We study the possibility to undo the quantum mechanical evolution in a time reversal experiment. The naive expectation, as reflected in the common terminology ("Loschmidt echo"), is that maximum compensation results if the reversed dynamics extends to the same time as the forward evolution. We challenge this belief and demonstrate that the time t(r) for maximum return probability is in general shorter. We find that t(r) depends on lambda=epsilon(evol)/epsilon(prep), being the ratio of the error in setting the parameters (fields) for the time-reversed evolution to the perturbation which is involved in the preparation process. Our results should be observable in spin-echo experiments where the dynamical irreversibility of quantum phases is measured.

Continuous-time quantum walks in phase space

Oliver Mülken, A. Blumen

We formulate continuous time quantum walks (CTQW) in a discrete quantum mechanical phase space. We define and calculate the Wigner function (WF) and its marginal distributions for CTQWs on circles of arbitrary length $N$. The WF of the CTQW shows characteristic features in phase space. Revivals of the probability distributions found for continuous and for discrete quantum carpets do manifest themselves as characteristic patterns in phase space.

Quantum walkers caught in a loop

Ian S. Osborne

Quantum Optics A quantum walk is the quantum mechanical analog of a classical random walk, describing the propagation of quantum walkers (photons) through an optical circuit. Because quantum walks generate large-scale quantum superposed states, they can be used for simulating many-body quantum systems and the development of algorithms for quantum computation. Nejadsattari et al. describe the photonic simulation with cyclic quantum systems. Using a multiple-site optical system, they explored the wave function dynamics and the probability distribution of quantum walkers as they loop through the system from site to site. With the ability to simulate a variety of different quantum operations and gates, they claim that the versatility of the approach should allow the study of more complex many-body systems.

Quantum Walks

Takuya Machida

Quantum walks are quantum counterparts of random walks. While probability distributions of random walks diffusively spread out as the walkers are updating, quantum walks have ballistic behavior. Some of the ballistic behaviors have been revealed in long-time limit theorems and their probability distributions are all far away from the Gaussian distributions, which are known as limit distributions of random walks. In this chapter, we are going to be seeing limit distributions for a standard quantum walk on the line and two kinds of time-dependent quantum walk on the line.
