Entanglement manipulation via dynamics in multiple quantum spin systems

Andrea Casaccino, Stefano Mancini, Simone Severini

We study manipulation of entanglement between two identical networks of quantum mechanical particles. Firstly, we reduce the problem of entanglement transfer to the problem of quan…

Quantum state transfer through a qubit network with energy shifts and fluctuations

Andrea Casaccino, Seth Lloyd, Stefano Mancini +1

We study quantum state transfer through a qubit network modeled by spins with XY interaction, when relying on a single excitation. We show that it is possible to achieve perfect tr…

Communication in XYZ All-to-All Quantum Networks with a Missing Link

Sougato Bose, Andrea Casaccino, Stefano Mancini +1

We explicitate the relation between Hamiltonians for networks of interacting qubits in the XYZ model and graph Laplacians. We then study evolution in networks in which all sites ca…

Extrema of discrete Wigner functions and applications

Andrea Casaccino, Ernesto F. Galvao, Simone Severini

We study the class of discrete Wigner functions proposed by Gibbons et al. [Phys. Rev. A 70, 062101 (2004)] to describe quantum states using a discrete phase-space based on finite…

An application of the Deutsch-Josza algorithm to formal languages and the word problem in groups

Michael Batty, Andrea Casaccino, Andrew J. Duncan +2

We adapt the Deutsch-Josza algorithm to the context of formal language theory. Specifically, we use the algorithm to distinguish between trivial and nontrivial words in groups give…

Quantum Error Correcting Subsystem Codes From Two Classical Linear Codes

Dave Bacon, Andrea Casaccino

The essential insight of quantum error correction was that quantum information can be protected by suitably encoding this quantum information across multiple independently erred qu…
