SUMMARY:Hybrid Quantum Information Processing with Circuit QED\, R. G.
  Herb Condensed Matter Seminar\, David Schuster\, University of Chicag
 o
DESCRIPTION:Quantum computing represents an enormous challenge with th
 e competing requirements of fast manipulation\, long storage\, and lon
 g distance transport of fragile quantum states. Individually these goa
 ls have been realized with nanosecond manipulations (quantum circuits)
 \, coherence times measured in seconds (atomic ions/nuclear spins)\, a
 nd entanglement transported over kilometers (linear optics). Yet thus 
 far no system has achieved all of the necessary components simultaneou
 sly. Just as classical computers have evolved to make use of magnetic\
 , charge\, and optical technologies\, perhaps the ultimate realization
  of a quantum computer will also involve hybrid quantum systems. I wil
 l describe how superconducting circuits can be used to manipulate sing
 le photons\, and how they can act as a universal quantum bus to interf
 ace with many other physical systems. This hybrid approach can both im
 prove prospects for quantum information science as well as illuminate 
 new physics of the component systems. As a specific example\, I will s
 how how superconducting circuits can be coupled to mesoscopic spin ens
 embles which might serve as a high fidelity quantum memory and also pr
 ovide a means to access broadband\, low temperature (millikelvin)\, ul
 tra low power (attowatt) electron spin resonance.
