Dynamical Autler-Townes control of a phase qubit

September 10, 2012
Author(s)
Jian Li, G.S. Paraoanu, Katarina Cicak, Fabio Altomare, Jae Park, Raymond Simmonds, Mika A. Sillanpaa, Pertti Hakonen
We present an experimental demonstration of a phase qubit acting as an on/o® switch for the absorbtion of photons in a probe microwave beam. The switch is controlled by a second control microwave ¯eld. The on/o® states of the qubit are steady states which

Decoherence, Autler-Townes effect, and dark states in two-tone driving of a three-level superconducting system

September 30, 2011
Author(s)
Jian Li, G.S. Paraoanu, Katarina Cicak, Fabio Altomare, Jae Park, Raymond Simmonds, Mika A. Sillanpaa, Pertti Hakonen
We present a detailed theoretical and experimental study of a multi-level quantum system coupled to two radiation ¯elds and subject to decoherence. We concentrate on an e®ect known from quantum optics as the Autler-Townes splitting, which has been recently

Tripartite interactions between two phase qubits and a resonant cavity

August 1, 2010

Fabio Altomare, Jae Park, Katarina Cicak, Mika Sillanpaa, Michael S. Allman, Adam J. Sirois, Joshua Strong, Jed D. Whittaker, Raymond Simmonds
The ability to create and manipulate the entanglement of a large number of quantum systems lies at the heart of emerging quantum information technologies. Thus far, multipartite entanglement has been achieved using various forms of quantum bits (qubits)

Electromagnetically induced transparency in a superconducting three-level system

April 16, 2009
Author(s)
Mika Sillanpaa, Katarina Cicak, Fabio Altomare, Jae Park, Raymond Simmonds, Jian Li, G. S. Paraoanu, Pertti Hakonen
When a three-level quantum system is irradiated by an intense coupling field resonant with two of the three possible transitions, the resonant absorption of the system from its ground state by an additional radiation field is suppressed. This effect, where

Superfludity and phase transitions in a resonant Bose gas

October 1, 2008

Leo Radzihovsky, Peter B. Weichman, Jae Park
The atomic Bose gas is studied across a Feshbach resonance, mapping out its phase diagram, and computing its thermodynamics and excitation spectra. It is shown that such a degenerate gas admits two distinct atomic and molecular superfluid phases, with the
