Modelling Decoherence in Quantum Lattice Gases

by Peter Love (Tufts Univ. Math. Dept.)

ABSTRACT

Quantum lattice gases are known to reproduce the Dirac equation in 
one dimension and the Schroedinger equation in D dimensions. They 
also represent quantum algorithms for the simulation of quantum 
systems with an exponential performance advantage over their 
implementation on classical computers. These models are therefore of 
interest both as classical algorithms for modelling quantum systems 
and as algorithms which may be efficiently implemented on future 
quantum computers.

In both cases, the role of decoherence arising from the interaction 
of the model with an environment is of interest. If we consider these 
models in the context of simulation of quantum systems, the 
introduction of an environment is of interest from the point of view 
of correspondence. If we consider these models as quantum algorithms 
the introduction of an environment enables us to study the effect of 
a finite error rate in our quantum computer. In this talk, we discuss 
one method of coupling quantum lattice gases to an environment and 
present simulation and analytic results for this error model.


Next week's feature: Paolo Zanardi (ISI, Italy) will speak on 
"Bipartite Entanglement and Entropic Boundary Law in Lattice Spin 
Systems".
