Fully superconducting Bloch-oscillating transistor: Amplification and bifurcation based on Bloch oscillations and counterflowing Cooper pairs
J. Leppäkangas, A. Puska, L. Äkäslompolo +2
The Bloch-oscillating transistor (BOT) is an amplifier that utilizes semiclassical dynamics of states in energy bands under traveling quasimomentum. In a BOT, a single quasiparticl…
Simulation of motional averaging using a superconducting circuit
J. Li, M. P. Silveri, K. S. Kumar +8
The possibility of using a quantum system to simulate another one has been recognized for a long time as an important research direction in quantum information and quantum computin…
Charge qubit driven via the Josephson nonlinearity
Jani Tuorila, Matti Silveri, Mika Sillanpää +3
We study the novel nonlinear phenomena that emerge in a charge qubit due to the interplay between a strong microwave flux drive and a periodic Josephson potential. We first analyze…
Motional Averaging in a Superconducting Qubit
Jian Li, M. P. Silveri, K. S. Kumar +8
Superconducting circuits with Josephson junctions are promising candidates for developing future quantum technologies. Of particular interest is to use these circuits to study effe…
Stark effect and generalized Bloch-Siegert shift in a strongly driven two-level system
Jani Tuorila, Matti Silveri, Mika Sillanpaa +3
A superconducting qubit was driven in an ultrastrong fashion by an oscillatory microwave field, which was created by coupling via the nonlinear Josephson energy. The observed Stark…
Interband transitions and interference effects in superconducting qubits
Antti Paila, Jani Tuorila, Mika Sillanpää +5
We investigate phase-sensitive interference effects in a periodically -driven, artificial two-state system connected to a microwave resonator at $f_{LC} \sime…
