Tripartite interactions between two phase qubits and a resonant cavity
F. Altomare, J. I. Park, K. Cicak +7
The creation and manipulation of multipartite entangled states is important for advancements in quantum computation and communication, and for testing our fundamental understanding…
Measurement crosstalk between two phase qubits coupled by a coplanar waveguide
Fabio Altomare, Katarina Cicak, Mika A. Sillanpää +8
We analyze the measurement crosstalk between two flux-biased phase qubits coupled by a resonant coplanar waveguide cavity. After the first qubit is measured, the superconducting ph…
Band Engineering in Cooper-Pair Box: Dispersive Measurements of Charge and Phase
Mika Sillanpaa, Leif Roschier, Teijo Lehtinen +1
Low-frequency susceptibility of the split Cooper-pair box (SCPB) is investigated for use in sensitive measurements of external phase or charge. Depending on the coupling scheme, th…
Landau-Zener interferometry with superconducting qubits
Mika Sillanpaa, Teijo Lehtinen, Antti Paila +2
Quantum-mechanical systems having two discrete energy levels are ubiquitous in nature. For crossing energy levels, depending on how fast they approach each other, there is a possib…
Direct measurements of tunable Josephson plasma resonance in the L-SET
Mika A. Sillanpaa, Leif Roschier, Pertti J. Hakonen
Phase dynamics has been measured in a driven mesoscopic Josephson oscillator where the resonance is tuned either by magnetic flux or by gate charge modulation of the Josephson indu…
Quantum capacitive phase detector
Leif Roschier, Mika Sillanpaa, Pertti Hakonen
We discuss how a single Cooper-pair transistor may be used to detect the superconducting phase difference by using the phase dependence of the input capacitance from gate to the gr…
