Comparing Classical Simulation and Sample-Based Learning of Quantum Systems
João Pedro d'El-Rey, Raúl O. Vallejos, Fernando de Melo
We investigate the relationship between two distinct classical approaches to quantum systems: direct simulation from a classical description and sample-based learning from measurem…
Spin-entanglement wave in a coarse-grained optical lattice
Pedro Silva Correia, Fernando de Melo
In the present work we explore a suitable coarse graining channel as a tool to describe the effective entanglement spreading in a coarse-grained spin-chain with different degrees o…
Quantum Walks via Quantum Cellular Automata
Pedro C. S. Costa, Renato Portugal, Fernando de Melo
Very much as its classical counterpart, quantum cellular automata are expected to be a great tool for simulating complex quantum systems. Here we introduce a partitioned model of q…
Detection and typicality of bound entangled states
Joonwoo Bae, Markus Tiersch, Simeon Sauer +4
We derive an explicit analytic estimate for the entanglement of a large class of bipartite quantum states which extends into bound entanglement regions. This is done by using an ef…
Scalability of GHZ and random-state entanglement in the presence of decoherence
Leandro Aolita, Daniel Cavalcanti, Antonio Acín +4
We derive analytical upper bounds for the entanglement of generalized Greenberger-Horne-Zeilinger states coupled to locally depolarizing and dephasing environments, and for local t…
Experimental investigation of the dynamics of entanglement: Sudden death, complementarity, and continuous monitoring of the environment
A. Salles, F. Melo, M. P. Almeida +4
We report on an experimental investigation of the dynamics of entanglement between a single qubit and its environment, as well as for pairs of qubits interacting independently with…
