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…
Parity readout in Majorana box qubits from the dispersive to the resonant regime
Sara M. Benjadi, Reinhold Egger
We study theoretical models for charge reflectometry and capacitive readout of the Majorana parity degree of freedom in Majorana box qubits, taking into account decoherence channel…
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…
Post-quench relaxation dynamics of Gross-Neveu lattice fermions
Domenico Giuliano, Reinhold Egger, Bidyut Dey +1
We study the quantum relaxation dynamics for a lattice version of the one-dimensional (1D) -flavor Gross-Neveu (GN) model after a Hamiltonian parameter quench. Allowing for a sy…
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…
