Implementation of the three-qubit phase-flip error correction code with superconducting qubits
L. Tornberg, M. Wallquist, G. Johansson +2
We investigate the performance of a three qubit error correcting code in the framework of superconducting qubit implementations. Such a code can recover a quantum state perfectly i…
Selective coupling of superconducting qubits via tunable stripline cavity
M. Wallquist, V. S. Shumeiko, G. Wendin
We theoretically investigate selective coupling of superconducting charge qubits mediated by a superconducting stripline cavity with a tunable resonance frequency. The frequency co…
Superconducting Quantum Circuits, Qubits and Computing
G. Wendin, V. S. Shumeiko
This paper gives an introduction to the physics and principles of operation of quantized superconducting electrical circuits for quantum information processing.
Dynamics and phonon-induced decoherence of Andreev level qubit
A. Zazunov, V. S. Shumeiko, G. Wendin +1
We present detailed theory for Andreev level qubit, the system consisting of a highly transmissive quantum point contact embedded in a superconducting loop. The two-level Hamiltoni…
Josephson junction qubit network with current-controlled interaction
J. Lantz, M. Wallquist, V. S. Shumeiko +1
We design and evaluate a scalable charge qubit chain network with controllable current-current coupling of neighbouring qubit loops via local dc-current gates. The network allows c…
Coherent multiple Andreev reflections and current resonances in SNS junctions
Å. Ingerman, G. Johansson, V. S. Shumeiko +1
We study coherent multiple Andreev reflections in quantum SNS junctions of finite length and arbitrary transparency. The presence of superconducting bound states in these junctions…
