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…
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…
Low-loss superconducting resonant circuits using vacuum-gap-based microwave components
Katarina Cicak, Dale Li, Joshua A. Strong +6
We have produced high-quality complex microwave circuits, such as multiplexed resonators and superconducting phase qubits, using a "vacuum-gap" technology that eliminates lossy die…
Autler-Townes effect in a superconducting three-level system
Mika A. Sillanpää, Jian Li, Katarina Cicak +5
When a three-level quantum system is irradiated by an intense coupling field resonant with one of the three possible transitions, the absorption peak of an additional probe field i…
