Electrical post-fabrication tuning of aluminum Josephson junctions at room temperature
Christian Križan, Maurizio Toselli, Irshad Ahmad +11
Josephson junctions are key elements of superconducting quantum technology, serving as the core building blocks of superconducting qubits. We present an experimental study on room-…
Quantum Acoustics with Tunable Nonlinearity in the Superstrong Coupling Regime
Marco Scigliuzzo, Léo Peyruchat, Riccardo Maria Marabini +4
Precise control of mechanical modes in the quantum regime is a key resource for quantum technologies, offering promising pathways for quantum sensing with macroscopic systems and s…
On-demand single-microwave-photon source in a superconducting circuit with wideband frequency tunability
Samarth Hawaldar, Siddhi Satish Khaire, Per Delsing +1
In this article, we propose a new method of generating single microwave photons in superconducting circuits. We theoretically show that pure single microwave photons can be generat…
Mitigation of interfacial dielectric loss in aluminum-on-silicon superconducting qubits
Janka Biznárová, Amr Osman, Emil Rehnman +9
We demonstrate aluminum-on-silicon planar transmon qubits with time-averaged energy relaxation times of up to , corresponding to Q = 5 million, and a highest obs…
Peripheral circuits for ideal performance of a travelling-wave parametric amplifier
Hampus Renberg Nilsson, Daryoush Shiri, Robert Rehammar +2
We investigate the required peripheral circuits to enable ideal performance for a high-gain travelling-wave parametric amplifier (TWPA) based on three-wave mixing (3WM). By embeddi…
