Engineered dissipation in cold atom mixtures
Abstract
BAA #: N00014-17-S-B001Dr. Trey Porto, Dr. Steven RolstonJoint Quantum Institute at University of Maryland, College Park and NISTAbstractThis research will explore ways to engineer quantum dissipation to be useful ratherthan problematic. But coupling to a dissipative channel can be important and useful, toremove entropy, a critical component of both classical and quantum informationprocessing. Any realistic quantum information processor is an open quantum system, andwill require control and understanding of dissipation.The researchers will explore a matter wave analogy to quantum optics, studying anopen quantum system where the reservoir is the phonon vacuum of a degenerate gas ratherthan the photon vacuum. Atoms trapped in an optical lattice will interact with a Bosecondensate of another species, and will dissipate energy into excitations in the condensate,in analogy to atoms dissipating energy through spontaneous emission into excitations ofthe electromagnetic vacuum. The wider range of control of the reservoir and the couplingwill allow for a greater understanding and possible control of dissipationin the quantum world.
