Quantum parallelism as a tool for ensemble spin dynamics calculations
Gonzalo A. Alvarez, Ernesto P. Danieli, Patricia R. Levstein +1
Efficient simulations of quantum evolutions of spin-1/2 systems are relevant for ensemble quantum computation as well as in typical NMR experiments. We propose an efficient method…
Decoherence of many-spin systems in NMR: From molecular characterization to an environmentally induced quantum dynamical phase transition
Gonzalo A. Alvarez
The control of open quantum systems has a fundamental relevance for fields ranging from quantum information processing to nanotechnology. Typically, the system whose coherent dynam…
Signatures of a quantum dynamical phase transition in a three-spin system in presence of a spin environment
Gonzalo A. Alvarez, Patricia R. Levstein, Horacio M. Pastawski
We have observed an environmentally induced quantum dynamical phase transition in the dynamics of a two spin experimental swapping gate [J. Chem. Phys. 124, 194507 (2006)]. There,…
Decoherence under many-body system-environment interactions: a stroboscopic representation based on a fictitiously homogenized interaction rate
Gonzalo A. Alvarez, Ernesto P. Danieli, Patricia R. Levstein +1
An environment interacting with portions of a system leads to multiexponential interaction rates. Within the Keldysh formalism, we fictitiously homogenize the system-environment in…
