Chiral entanglement in triangular lattice models
Tsomokos, D.I.; Garcia-Ripoll, J.J.; Cooper, N.R.; Pachos, J.K. (2008)We consider the low-energy spectrum of spin- two-dimensional triangular lattice models subject to a ferromagnetic Heisenberg interaction and a three spin chiral interaction of variable strength. Initially, we consider ... -
Control-limited perfect state transfer, quantum stochastic resonance, and many-body entangling gate in imperfect qubit registers
Di Franco, C.; Paternostro, M.; Tsomokos, D.I.; Huelga, S.F. (2008)We propose a protocol for perfect quantum state transfer that is resilient to a broad class of realistic experimental imperfections, including noise sources that could be modeled either as independent Markovian baths or ... -
Correlation properties of interfering electrons in a mesoscopic ring under nonclassical microwave radiation
Tsomokos, D.I.; Chong, C.C.; Vourdas, A. (2003)Interfering electrons in a mesoscopic ring are irradiated with both classical and nonclassical microwaves. The average intensity of the charges is calculated as a function of time and it is found that it depends on the ... -
Correlations in interfering electrons irradiated by nonclassical microwaves
Chong, C.C.; Tsomokos, D.I.; Vourdas, A. (2002) -
Electron interference in mesoscopic devices in the presence of nonclassical electromagnetic fields
Tsomokos, D.I.; Chong, C.C.; Vourdas, A. (2005) -

Fully connected network of superconducting qubits in a cavity.
Tsomokos, D.I.; Ashhab, S.; Nori, F. (IOP Publishing, 2008)A fully connected qubit network is considered, where every qubit interacts with every other one. When the interactions between the qubits are homogeneous, the system is a special case of the finite Lipkin–Meshkov–Glick ... -
Photon-induced entanglement of distant mesoscopic SQUID
Vourdas, A.; Tsomokos, D.I.; Chong, C.C. (Springer Nature, 2006)An experiment that involves two distant mesoscopic SQUID rings is studied. The superconducting rings are irradiated with correlated photons, which are produced by a single microwave source. Classically correlated (separable) ... -
State transfer in highly connected networks and a quantum Babinet principle
Tsomokos, D.I.; Plenio, M.B.; de Vega, I.; Huelga, S.F. (2008)The transfer of a quantum state between distant nodes in two-dimensional networks, is considered. The fidelity of state transfer is calculated as a function of the number of interactions in networks that are described by ... -
Topological order following a quantum quench
Tsomokos, D.I.; Hamma, A.; Zhang, W.; Haas, S.; Fazio, R. (2009)We determine the conditions under which topological order survives a rapid quantum quench. Specifically, we consider the case where a quantum spin system is prepared in the ground state of the toric code model and, after ...
