Finite size corrections to random Boolean networks
Michele Leone, Andrea Pagnani, Giorgio Parisi +1
Since their introduction, Boolean networks have been traditionally studied in view of their rich dynamical behavior under different update protocols and for their qualitative analo…
Mixed-state fidelity and quantum criticality at finite temperature
Paolo Zanardi, H. T. Quan, Xiaoguang Wang +1
We extend to finite temperature the fidelity approach to quantum phase transitions (QPTs). This is done by resorting to the notion of mixed-state fidelity that allows one to compar…
Determination of ground state properties in quantum spin systems by single qubit unitary operations and entanglement excitation energies
S. M. Giampaolo, F. Illuminati, P. Verrucchi +1
We introduce a method for analyzing ground state properties of quantum many body systems, based on the characterization of separability and entanglement by single subsystem unitary…
Non-equilibrium phase transition in negotiation dynamics
A. Baronchelli, L. Dall'Asta, A. Barrat +1
We introduce a model of negotiation dynamics whose aim is that of mimicking the mechanisms leading to opinion and convention formation in a population of individuals. The negotiati…
Coexistence of unlimited bipartite and genuine multipartite entanglement: Promiscuous quantum correlations arising from discrete to continuous variable systems
Gerardo Adesso, Marie Ericsson, Fabrizio Illuminati
Quantum mechanics imposes 'monogamy' constraints on the sharing of entanglement. We show that, despite these limitations, entanglement can be fully 'promiscuous', i.e. simultaneous…
Entangling spins by measuring charge: a parity-gate toolbox
Radu Ionicioiu
The parity gate emerged recently as a promising resource for performing universal quantum computation with fermions using only linear interactions. Here we analyse the parity gate…
