Dynamical phase transitions at finite temperature from fidelity and interferometric Loschmidt echo induced metrics
Bruno Mera, Chrysoula Vlachou, Nikola Paunković +2
We study finite-temperature Dynamical Quantum Phase Transitions (DQPTs) by means of the fidelity and the interferometric Loschmidt Echo (LE) induced metrics. We analyse the associa…
Quantum key distribution with quantum walks
Chrysoula Vlachou, Walter Krawec, Paulo Mateus +2
Quantum key distribution is one of the most fundamental cryptographic protocols. Quantum walks are important primitives for computing. In this paper we take advantage of the proper…
The Uhlmann connection in fermionic systems undergoing phase transitions
Bruno Mera, Chrysoula Vlachou, Nikola Paunković +1
We study the behaviour of the Uhlmann connection in systems of fermions undergoing phase transitions. In particular, we analyse some of the paradigmatic cases of topological insula…
