Exponential Speedup of Entanglement Generation by Quantum Mpemba Effects
Sara M. Benjadi, Reinhold Egger, Igor Gornyi +1
Entanglement is a key resource for quantum technologies. We show that protocols employing quantum Mpemba effects allow one to exponentially accelerate the generation of entanglemen…
DC Conductance of X-shaped Majorana Interferometer reveals Non-Abelian Anyon Statistics
Domenico Giuliano, Andrea Nava, Reinhold Egger +1
We propose a four-terminal, X-shaped chiral Majorana interferometer with a central floating superconducting island, enabling the direct detection of the non-Abelian statistics of I…
Optimal speed-up of multi-step Pontus-Mpemba protocols
Marco Peluso, Reinhold Egger, Andrea Nava
The classical Mpemba effect is the counterintuitive phenomenon where hotter water freezes faster than colder water due to the breakdown of Newton's law of cooling after a sudden te…
Information transport and transport-induced entanglement in open fermion chains
Andrea Nava, Claudia Artiaco, Yuval Gefen +4
Understanding the entanglement dynamics in quantum many-body systems under steady-state transport conditions is an actively pursued challenging topic. Hydrodynamic equations, akin…
Speeding up Pontus-Mpemba effects via dynamical phase transitions
Andrea Nava, Reinhold Egger, Bidyut Dey +1
We demonstrate that open quantum systems exhibiting dynamical phase transitions (DPTs) allow for efficient protocols implementing the Pontus-Mpemba effect. The relaxation speed-up…
Pontus-Mpemba effects
Andrea Nava, Reinhold Egger
Mpemba effects occur after a sudden quench of control parameters if for ''far'' (or ''hot'') initial states with respect to a final target state, the relaxation time toward the tar…
