We study the formation of a Bose-Einstein condensate in cigar-shaped three-dimensional harmonic trap, induced by controlled addition an attractive ``dimple'' potential along weak axis. In this manner we are able to induce condensation without cooling due localized increase phase-space density. perform quantitative analysis thermodynamic transformation both sudden and adiabatic regimes for range dimple widths depths. find good agreement with equilibrium calculations based on self-consistent...
Across industries, traditional design and engineering workflows are being upgraded to simulation-driven processes. Many include computational fluid dynamics (CFD). Simulations of turbulent flow notorious for high compute costs reliance on approximate methods that compromise accuracy. Improvements in the speed accuracy CFD calculations would potentially reduce workflow by reducing eliminating need experimental testing. This study explores feasibility using fault-tolerant quantum computers...
We study the equilibrium correlations of a Bose gas in an elongated three-dimensional harmonic trap using grand-canonical classical-field method. focus particular on progressive transformation from normal phase, through phase-fluctuating quasicondensate regime to so-called true-condensate regime, with decreasing temperature. Choosing realistic experimental parameters, we quantify density fluctuations and phase coherence atomic field as functions system identify onset condensation analysis...
The cluster state, the highly entangled state that is central resource for one-way quantum computing, can be efficiently generated in a variety of physical implementations via global nearest-neighbor interactions. In practice, systematic phase error expected entangling process, resulting imperfect states. We present stochastic measurement technique to generate large perfect states and other graph with high probability from even when their initial entanglement weak.
Dilute gas Bose-Einstein condensates (BECs) are an example of a superfluid, and exhibit many the same phenomena as strongly interacting superfluid helium. However, their isolation from environment combined with inhomogeneous density profiles make it difficult to observe some phenomena, such thermo-mechanical effect, in experiments. Here we perform dynamical simulations finite temperature condensate coupled spatially separated heat particle reservoirs non-equilibrium phenomena. We analyse...
