Superconductor modulation circuits for Qubit control at microwave frequencies
Sasan Razmkhah, Ali Bozbey, Pascal Febvre
Readout and control of qubits are limiting factors in scaling quantum computers. An ideal solution is to integrate energy-efficient cryogenic circuits close to the qubits to perfor…
A Compact High Frequency Voltage Amplifier for Superconductor-Semiconductor Logic Interface
Sasan Razmkhah, Ali Bozbey, Pascal Febvre
The many advantages of cryogenically-cooled Single-Flux Quantum (SFQ) circuits imply that the high speed and low voltage output signals must be amplified and interfaced with standa…
Study of microwave resonances induced by bias lines of shunted Josephson junctions
Ugur Yilmaz, Sasan Razmkhah, Romain Collot +3
Bias lines routed over a ground plane naturally form microstrip lines associated with the presence of a capacitance. This can lead to unwanted resonances when coupled to Josephson…
JOINUS: A User-friendly Open-source Software to Simulate Digital Superconductor Circuits
Sasan Razmkhah, Pascal Febvre
Single flux quantum (SFQ) based circuits are the subject of renewed attention due to their high speed and their very high energy efficiency. However, the need of cryogenic temperat…
Ion-irradiated YBaCuO Josephson arrays
A. Sharafiev, M. Malnou, C. Feuillet-Palma +4
We designed, fabricated and tested short one dimensional arrays of masked ion-irradiated YBaCuO Josephson junctions (JJ) embedded into log-periodic spiral antennas. Our…
Josephson oscillation linewidth of ion-irradiated YBaCuO junctions
A. Sharafiev, M. Malnou, C. Feuillet-Palma +4
We report on the noise properties of ion-irradiated YBaCuO Josephson junctions. This work aims at investigating the linewidth of the Josephson oscillation with a detect…
Josephson mixers for terahertz detection
Maxime Malnou, Cheryl Feuillet-Palma, Christian Ulysse +6
We report on an experimental and theoretical study of the high-frequency mixing properties of ion-irradiated YBa2Cu3O7 Josephson junctions embedded in THz antennas. We investigated…
Inductance measurement of YBCO strip-lines made by ion irradiation
T. Wolf, N. Bergeal, C. Ulysse +3
We have investigated the electrodynamic properties of High-Tc strip-lines made by ion irradiation, in order to evaluate the potentialities of such a technology for RSFQ superconduc…
