Universal computation of a quantum system consisting of superpositions of well-separated
coherent states of multiple harmonic oscillators can be achieved by three families of …

Nonclassical properties of electromagnetic radiation propagating through a non-degenerate
parametric amplifier (NDPA) are investigated. A complete quantum mechanical description …

In this work, we propose the nonlocal tunneling mechanism for high-fidelity state transfer
between distant parties. The nonlocal tunneling follows from the overlap between the distant …

The Hamiltonian and the corresponding equations of motion involving the field operators of
two quartic anharmonic oscillators indirectly coupled via a linear oscillator are constructed …

We present a scheme for quasiperfect transfer of polariton states from a sender to a spatially
separated receiver, both composed of high-quality cavities filled by atomic samples. The …

We present a protocol for high-fidelity information transfer and processing between remote
multi-branch nonideal quantum circuits (QCs). A set of outputs of a QC is simultaneously …

We present a technique to build, within a dissipative bosonic network, decoherence-free
channels (DFCs): a group of normal-mode oscillators with null effective damping rates. We …

We study a reservoir engineering scheme whose steady-state space consists of
superpositions of d wellseparated coherent states. We show that universal computation on …

Neste trabalho, descrevemos vários protocolos para a geração de estados estacionários
não clássicos, suportados principalmente pela engenharia de hamiltonianos seletivos …

Nesta tese abordamos o problema de transferência e manipulação de informação quântica
em sistemas dissipativos. Inicialmente apresentamos uma técnica para construir, dentro de …
