Experimental linear-optics simulation of the ground state of an interacting quantum spin-ring
Adeline Orieux, Joelle Boutari, Marco Barbieri +2
Critical phenomena involve a structural change in the correlations of its constituents. These features can be employed in quantum simulators to assess when a criticality occurred i…
Reconfigurable long-range phonon dynamics in optomechanical arrays
André Xuereb, Claudiu Genes, Guido Pupillo +2
We investigate periodic optomechanical arrays as reconfigurable platforms for engineering the coupling between multiple mechanical and electromagnetic modes and for exploring many-…
Competition between memory-keeping and memory-erasing decoherence channels
Tony J. G. Apollaro, Salvatore Lorenzo, Carlo Di Franco +2
We study the competing effects of simultaneous Markovian and non-Markovian decoherence mechanisms acting on a single spin. We show the existence of a threshold in the relative stre…
Localization-like effect in two-dimensional alternate quantum walks with periodic coin operations
Carlo Di Franco, Mauro Paternostro
Exploiting multi-dimensional quantum walks as feasible platforms for quantum computation and quantum simulation is attracting constantly growing attention from a broad experimental…
Master equation for dissipative interacting qubits in a common environment
J. P. Santos, F. L. Semião
In this paper, we derive a microscopic master equation for a pair of XY-coupled two-level systems interacting with the same memoryless reservoir. In particular, we apply this maste…
Experimental realisation of a delayed-choice quantum walk
Youn-Chang Jeong, Carlo Di Franco, Hyang-Tag Lim +2
Many paradoxes of quantum mechanics come from the fact that a quantum system can possess different features at the same time, such as in wave-particle duality or quantum superposit…
