Talk Title: Emerging Quantum Optical Networks
Abstract: Economic and environmental pressures continually push information systems smaller and to operate at lower energies. As a consequence, optical technologies are increasingly utilized to connect computing devices over short distances. For similar reasons and in view of recent advances in nanophotonics, large scale electro-optical integration in processors could also be advantageous. These trends raise some fundamental hardware questions, however. For example, the energy equivalent of todayâs CMOS logic operation is a countable number of photons. How could we control a physical optical âbitâ with significant quantum noise? Can the full quantum complexity and emergent behavior of an optical network be engineered?
The stability problem is illustrated by a recent experiment in which quantum fluctuations destabilize bistability (a canonical context for digital logic) in an ultra-low energy, highly non-linear optical device. On the other hand, the emergence of a new binary switching phenomena in this device is also compelling. I will discuss a proposal for stabilizing related devices with a simple, on-chip and all-optical feedback network, utilizing a nascent theory of quantum optical circuits that resembles a non-commutative generalization of electrical circuit theory. Finally, I will describe a potential all-optical feedback network capable of stabilizing an unknown quantum superposition state without external oversight or even a regulating âclock,â demonstrating the wide scope of quantum optical control.
Biography: Joseph Kerckhoff received a B.A. in Physics and English from Williams College in 2005, graduating magna cum laude. As a graduate student in the group of Hideo Mabuchi first at the California Institute of Technology and then at Stanford University, his research focused on cavity quantum electrodynamics experiments and theoretical quantum optical control networks. Receiving his Ph.D. in Applied Physics from Stanford in June 2011, Joseph is a National Research Council postdoctoral research fellow at JILA (NIST and the U. of Colorado) working on coherent feedback systems with superconducting microwave and quantum electro-mechanical devices in the group of Konrad Lehnert.
