Verification of stable operation of rapid single flux quantum devices with selective dissipation
J. Hassel, L. Gronberg, P. Helisto
It has been suggested that Rapid Single Flux Quantum (RSFQ) devices could be used as the classical interface of superconducting qubit systems. One problem is that the interface act…
Description of self-synchronization effects in distributed Josephson junction arrays using harmonic analysis and power balance
J. Hassel, L. Gronberg, P. Helisto +1
Power generation and synchronisation in Josephson junction arrays have attracted attention for a long time. This stems from fundamental interest in nonlinear coupled systems as wel…
Characterization of a fabrication process for the integration of superconducting qubits and RSFQ circuits
Maria Gabriella Castellano, Leif Gronberg, Pasquale Carelli +7
In order to integrate superconducting qubits with rapid-single-flux-quantum (RSFQ) control circuitry, it is necessary to develop a fabrication process that fulfills at the same tim…
RSFQ devices with selective dissipation for quantum information processing
J. Hassel, H. Seppa, P. Helisto
We study the possibility to use frequency dependent damping in RSFQ circuits as means to reduce dissipation and consequent decoherence in RSFQ/qubit circuits. We show that stable R…
Theory of the Bloch Oscillating Transistor
J. Hassel, H. Seppa
The Bloch oscillating transistor (BOT) is a device, where single electron current through a normal tunnel junction can be used to enhance Cooper pair current in a mesoscopic Joseph…
Control of Coulomb blockade in a mesoscopic Josephson junction using single electron tunneling
J. Hassel, J. Delahaye, H. Seppa +1
We study a circuit where a mesoscopic Josephson junction (JJ) is embedded in an environment consisting of a large bias resistor and a normal metal - superconductor tunnel junction…
