The benefit of doing things slowly : employing dissipation for the robust creation of entanglement between ions in spatially separate cavities
Plenio, M.B.; Browne, D.E.; Huelga, S.F. (SPIE, 2003)We present protocol that allows the generation of a maximallyentangled state between individual atoms held in spatiallyseparate cavities. Under ideal conditions, the scheme isdeterministic. In a realistic setting, when the ... -
Cavity-loss-induced generation of entangled atoms
Plenio, M.B.; Huelga, S.F.; Beige, A.; Knight, P.L. (1999)We discuss the generation of entangled states of two two-level atoms inside an optical resonator. When the cavity decay is continuously monitored, the absence of photon-counts is associated with the presence of an atomic ... -
Classical simulability, entanglement breaking and quantum computation threshold

Dephasing-assisted transport: quantum networks and biomolecules
Plenio, M.B.; Huelga, S.F. (2008)Transport phenomena are fundamental in physics. They allow for information and energy to be exchanged between individual constituents of communication systems, networks or even biological entities. Environmental noise will ... -

Entanglement and entangling power of the dynamics in light-harvesting complexes
Caruso, F.; Chin, A.W.; Datta, A.; Huelga, S.F.; Plenio, M.B. (2010)We study the evolution of quantum entanglement during exciton energy transfer (EET) in a network model of the Fenna-Matthews-Olson (FMO) complex, a biological pigment-protein complex involved in the early steps of ... -
Entanglement and Non-Markovianity of Quantum Evolutions
Rivas, A.; Huelga, S.F.; Plenio, M.B. (2010)We address the problem of quantifying the non-Markovian character of quantum time evolutions of general systems in contact with an environment. We introduce two different measures of non-Markovianity that exploit the ... -
Entanglement dynamics in chains of qubits with noise and disorder
Tsomokos, D.I.; Hartmann, M.J.; Huelga, S.F.; Plenio, M.B. (2007) -
Entanglement in frequency standards and quantum information theory
Huelga, S.F.; Knight, P.L.; Macchiavello, C.; Plenio, M.B.; Vedral, V. (1998)Entanglement is a key property of quantum information theory. Here we describe ways to quantify the amount of entanglement.We point out the statistical interpretation of these entanglement measures and some connections ... -

Beige, A.; Braun, D.; Bose, S.; Huelga, S.F.; Knight, P.L.; Plenio, M.B.; Vedral, V. (2000) -
Highly efficient energy excitation transfer in light-harvesting complexes : the fundamental role of noise-assisted transport
Caruso, F.; Chin, A.W.; Datta, A.; Huelga, S.F.; Plenio, M.B. (2009)Excitation transfer through interacting systems plays an important role in many areas of physics, chemistry, and biology. The uncontrollable interaction of the transmission network with a noisy environment is usually assumed ... -
Improvement of frequency standards with quantum entanglement
Huelga, S.F.; Macchiavello, C.; Pellizzari, T.; Ekert, A.K.; Plenio, M.B.; Cirac, J. (1997)The optimal precision of frequency measurements in the presence of decoherence is discussed. We analyse different preparations of n two-level systems as well as different measurements procedures. We show that standard ... -
Noise-assisted energy transfer in quantum networks and light-harvesting complexes
Chin, A.W.; Datta, A.; Caruso, F.; Huelga, S.F.; Plenio, M.B. (2010)We provide physically intuitive mechanisms for the effect of noise on excitation energy transfer (EET) in networks. Using these mechanisms of dephasing-assisted transport (DAT) in a hybrid basis of both excitons and sites, ... -
