Optical probing of mechanical loss of a Si_{3}N_{4} membrane below 100 mK
R. Fischer, N. S. Kampel, G. G. T. Assumpção +5
We report on low mechanical loss in a high-stress silicon nitride (Si_{3}N_{4}) membrane at temperatures below 100 mK. We isolate a membrane via a phononic shield formed within a s…
A phononic bandgap shield for high-Q membrane microresonators
P. -L. Yu, K. Cicak, N. S. Kampel +4
A phononic crystal can control the acoustic coupling between a resonator and its support structure. We micromachine a phononic bandgap shield for high Q silicon nitride membranes a…
Quantum interference between two single photons of different microwave frequencies
François Nguyen, Eva Zakka-Bajjani, Raymond W. Simmonds +1
We have measured quantum interference between two single microwave photons trapped in a superconducting resonator, whose frequencies are initially about 6 GHz apart. We accomplish…
Quantum superposition of a single microwave photon in two different "colour" states
Eva Zakka-Bajjani, François Nguyen, Minhyea Lee +3
The ability to coherently couple arbitrary harmonic oscillators in a fully-controlled way is an important tool to process quantum information. Coupling between quantum harmonic osc…
Dynamical Autler-Townes control of a phase qubit
Jian Li, G. S. Paraoanu, Katarina Cicak +5
Routers, switches, and repeaters are essential components of modern information-processing systems. Similar devices will be needed in future superconducting quantum computers. In t…
Decoherence, Autler-Townes effect, and dark states in two-tone driving of a three-level superconducting system
Jian Li, G. S. Paraoanu, Katarina Cicak +5
We present a detailed theoretical analysis of a multi-level quantum system coupled to two radiation fields and subject to decoherence. We concentrate on an effect known from quantu…
