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 SWAP gate realized with CZ and iSWAP gates in a superconducting architecture

Christian Križan, Janka Biznárová, Liangyu Chen +19

It is advantageous for any quantum processor to support different classes of two-qubit quantum logic gates when compiling quantum circuits, a property that is typically not seen wi…

Signal crosstalk in a flip-chip quantum processor

Sandoko Kosen, Hang-Xi Li, Marcus Rommel +15

Quantum processors require a signal-delivery architecture with high addressability (low crosstalk) to ensure high performance already at the scale of dozens of qubits. Signal cross…

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…

Measurement and control of a superconducting quantum processor with a fully-integrated radio-frequency system on a chip

Mats O. Tholén, Riccardo Borgani, Giuseppe Ruggero Di Carlo +8

We describe a digital microwave platform called Presto, designed for measurement and control of multiple quantum bits (qubits) and based on the third-generation radio-frequency sys…
