The energy level splitting for unharmonic dc-SQUID to be used as phase Q-bit
Physica C: Superconductivity and its Applications, 2006Abstract Dc-SQUID with Josephson junctions characterized by nonsinusoidal current-phase relation is being considered as a basis for phase qubit. It has been shown that the second and third harmonic components each in the current-phase relation are able to provide double-well potential and the energy level splitting. Threshold condition for the double-

Violation of Bell Inequality with the Fractional Momentum of the photon: a step towards a new q-bit
Conference on Coherence and Quantum Optics, 2007Bell inequality is violated with transverse spatial variables of twin photons, through optical implementation of Fractional Fourier Transforms. A q-bit can be constructed and manipulated in the same way, with promising applications to quantum information.

Flying q-bits and entangled photons for quantum cryptography
2008 International Nano-Optoelectronics Workshop, 2008The excitonic ground state in a quantum dot shows a size- and shape-dependent two-fold splitting due to exchange interaction. By tuning the splitting q-bit emission from the exciton or entangled photon emission from the exciton/biexciton cascade are possible.

Phase-space dynamical model of an open system of interacting q-bits
Journal of Physics A: Mathematical and General, 2005Summary: The path integral form of the propagator for a stochastic Schrödinger equation is used to derive stochastic differential equations on the quantum phase space of interacting \(q\)-bits in a random environment. The equations can be considered as an approximate 'classical' model of the quantum system.

Abstract We have studied the spin dynamics in nonintentionally doped and n-modulation doped self-organized InAs/GaAs quantum dots (QD) by time-resolved photoluminescence. Under strictly resonant excitation, we demonstrate that the carrier spins in these nanostructures are totally frozen on the neutral or charged exciton lifetime scale.

Transferência de estados de dois Q-bits usando cavidades e fibras ópticas com um ou dois modos
Physicae Proceedings, 2011Em diferentes trabalhos desenvolvem-se estudos de um sistema de duas cavidades acopladas com dois ions aprisionados, um em cada uma delas adotando-se diferentes meios de transmissao de estados entre os ions. Um fato comum entre os diferentes estudos e que so se toma um modo da cavidade; para transmitir a informacao.

One of the key tasks in Hardware-Software Co-design is to optimally allocate, assign, and schedule resources to achieve a good balance among performance, cost, power consumption, etc. So it's a typical multi-objective optimization problem. In this paper, a Multi-objective Q-bit coding genetic algorithm (MoQGA) is proposed to solve HW-SW co-synthesis ...

Um q-bit pode ser entendido como um sistema quântico de dois níveis, cuja representação tradicional é um vetor de estado no espaço de Hilbert, e operações reversíveis sobre q-bits são implementadas a partir de transformações unitárias. Neste trabalho, o objetivo é estudar essas operações sob um ponto de vista geométrico, aplicando ferramentas ...
