- Abstract: We present the first manifestation of a Parrondo's effect in a
continuous-time quantum walk (CTQW). In our protocol we consider a CTQW in the
presence of time-dependent transition defect. Our results show that the
alternation between defects, that individually are detrimental to the
wavepacket spreading, can paradoxically enhance overall wavepacket propagation.
Our findings pave the way for the exploration of unconventional mechanisms that
can potentially harness the adverse effects of defects to enhance quantum
transport.

We present a study of crosstalk errors in a quantum-computing architecture based on a single string of ions confined by a radio-frequency trap, and manipulated by individually-addressed laser beams.
This type of errors affects spectator qubits that, ideally, should remain unaltered during the application of single- and two-qubit quantum gates addressed at a different set of active qubits.
We microscopically model crosstalk errors from first principles and present a detailed study showing the importance of using a coherent vs incoherent error modelling and, moreover, discuss strategies to actively suppress this crosstalk at the gate level.

We demonstrate how quantum time dilation manifests in a spontaneous emission process.

We argue that spectroscopic experiments offer a technologically feasible platform to explore the effects of quantum time dilation.

We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit.
We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront.
The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
