![]() The numerical simulation indicates that classical viscous damping is not present in the one-dimensional quantum lattice-gas system. A symbolic mathematical method is used to implement the quantum mechanical model on a conventional workstation. The Quantum Fluid Dynamics (QFD) representation has its foundations in the works of Madelung, De Broglie and Bohm. We use a two-dimensional (2D) fluid of polaritons, bosonic particles constituted by hybrid photonic and electronic oscillations, to study quantum vortex. ![]() Numerical results obtained from an exact simulation of a one-dimensional quantum lattice model are included to illustrate the formalism. At the mesoscopic scale, a lattice Boltzmann equation with a nonlocal collision term that depends on the entire system wave function, governs the dynamical system. An analytical treatment of the microscopic quantum lattice-gas system is carried out to predict its behavior at the mesoscopic scale. It is an interpretation of quantum mechanics with the goal to find classically identifiable dynamical variables at the sub-particle level. The quantum algorithm is called a quantum lattice gas. What is quantum fluid dynamics The Quantum Fluid Dynamics (QFD) representation has its foundations in the works of Madelung, De Broglie and Bohm. Hence, this paper addresses two separate areas of physics: quantum mechanics and fluid dynamics (or specifically, the computational simulation of fluid dynamics). ![]() Quantum-computing ideas are applied to the practical and ubiquitous problem of fluid dynamics simulation.
