Quantum Computation with Bose-Einstein Condensates
نویسنده
چکیده
It is proposed that quantum computation can be implemented on the basis of macroscopic quantum coherence of a many-particle system, especially the Bose-Einstein condensates, instead of a pure state. Moreover, since a macroscopic condensate “wavefunction” is described by a nonlinear Schrödinger equation, and the nonlinearity is tunable, one may be able to build a quantum computer composed of both linear and nonlinear gates in order to solve NP-complete and #P problems. This idea is illustrated in terms of BoseEinstein condensation of trapped atoms. PACS numbers: 03.67.Lx,03.75.Fi Typeset using REVTEX

Quantum Computation using Two Component Bose-Einstein Condensates
Quantum computation using qubits made of two component Bose-Einstein condensates (BECs) is analyzed. We construct a general framework for quantum algorithms to be executed using the collective states of the BECs. The use of BECs allows for an increase of energy scales via bosonic enhancement, resulting in two qubit gate operations that can be performed at a time reduced by a factor of N , where...
متن کاملQuantum non-demolition measurements using Bose-Einstein condensates
We study possible scenarios for quantum non-demolition measurements using Bose-Einstein condensates. We show that the interactions between condensate atoms makes it possible to measure the atom number with minimal back action on the system. This is an example of atomic nonlinear optics that has significant implications in the quantum state preparation of the Bose condensates. Typeset using REVT...
متن کاملSpectral stability of vortices in two-dimensional Bose-Einstein condensates via the Evans function and Krein signature
We investigate spectral stability of vortex solutions of the Gross-Pitaevskii equation, a mean-field approximation for Bose-Einstein condensates (BEC) in an effectively two-dimensional axisymmetric harmonic trap. We study eigenvalues of the linearization both rigorously and through computation of the Evans function, a sensitive and robust technique whose use we justify mathematically. Computati...
متن کاملSpin squeezing in a bimodal condensate: spatial dynamics and particle losses
We propose an analytical method to study the entangled spatial and spin dynamics of interacting bimodal Bose-Einstein condensates. We show that at particular times during the evolution spatial and spin dynamics disentangle and the spin squeezing can be predicted by a simple two-mode model. We calculate the maximum spin squeezing achievable in experimentally relevant situations with Sodium or Ru...
متن کاملObservation of Metastable States in Spinor Bose-Einstein Condensates
Bose-Einstein condensates have been prepared in long-lived metastable excited states. Two complementary types of metastable states were observed. The first is due to the immiscibility of multiple components in the condensate, and the second to local suppression of spin-relaxation collisions. Relaxation via recondensation of noncondensed atoms, spin relaxation, and quantum tunneling was observed...
