Photonics is a promising platform for demonstrating a quantum computational advantage
(QCA) by outperforming the most powerful classical supercomputers on a well-defined …

Signaled by nonanalyticities in the time evolution of physical observables, dynamic quantum
phase transitions (DQPTs) emerge in quench dynamics of topological systems and possess …

Noise-enhanced applications in open quantum walk (QW) has recently seen a surge due to
their ability to improve performance. However, verifying the success of open QW is …

The competition between unitary time evolution and quantum measurements could induce
phase transitions in the entanglement characteristics of quantum many-body dynamics. In …

We study a quantum walk of a single particle that is subject to stroboscopic projective
measurements on a graph with two sites. This two-level system is the minimal model of a …

We propose active steering protocols for quantum state preparation in quantum circuits
where each system qubit is connected to a single detector qubit, employing a simple …

Recurrence is an interesting property that describes whether the walker will eventually
return to the origin on infinite lattices in classical random walks. Since measurement …

How long does it take a quantum particle to return to its origin? As shown previously under
repeated projective measurements aimed to detect the return, the closed cycle yields a …

We investigate a tight-binding quantum walk on a graph. Repeated stroboscopic
measurements of the position of the particle yield a measured “trajectory,” and a …

Quantum walks are processes that model dynamics in coherent systems. Their experimental
implementations proved to be key to unveiling novel phenomena in Floquet topological …
