Dissipatively Stabilized Qubits and Materials
Abstract
While dissipation and decoherence are usually viewed as factors, which limit the realization of quantum phenomena. Work over the past three decades has demonstrated that this need not be the case. Properly engineered and controlled dissipation can remove entropy from a many body system, or act as an autonomous, continuous measurement that constantly corrects errors in a quantum memory or quantum computer; it can even provide new types of interactions that transcend the limitations of purely unitary approaches, with realizations and potential utility in a wide range of physical systems. This MURI award will allow us to harness reservoir engineering to demonstrate the first dissipatively stabilized synthetic matter and autonomously corrected quantum processes. Combining experimental and theoretical work, we will develop a language to characterize the behavior and performance of such dissipative driving and build deep intuition for differences between driven-dissipative quantum systems and their equilibrium counterparts. We have assembled a team of leading quantum scientists with proven records of accomplishment for designing and implementing reservoir engineering. On the experimental side, team members have demonstrated that dissipation may be employed to remove entropy from a fluid of light, causing it to crystallize into a solid; to trap a harmonic oscillator in a manifold of cat states or to enhance the lifetime of a quantum memory; and to control dissipative phonon modes that couple pristine trapped ion qubits. On the theory side, team members have shown that dissipation can stabilize squeezing and entanglement and material phases, and developed quantum information processing protocols transparent to errors and compatible with dissipatively enhanced coherence.
