Entanglement swapping via three-step quantum walk-like protocol
Xiao-Man Li, Ming Yang, Nikola Paunkovic +2
We present an entanglement swapping process for unknown nonmaximally entangled photonic states, where the standard Bell-state measurement is replaced by a three-step quantum walk-l…
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…
Gauge protected entanglement between gravity and matter
Nikola Paunkovic, Marko Vojinovic
We show that gravity and matter fields are generically entangled, as a consequence of the local Poincaré symmetry. First, we present a general argument, applicable to any particula…
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…
