Building Blocks of a Flip-Chip Integrated Superconducting Quantum Processor
Sandoko Kosen, Hang-Xi Li, Marcus Rommel +24
We have integrated single and coupled superconducting transmon qubits into flip-chip modules. Each module consists of two chips -- one quantum chip and one control chip -- that are…
Robust preparation of Wigner-negative states with optimized SNAP-displacement sequences
Marina Kudra, Mikael Kervinen, Ingrid Strandberg +13
Hosting non-classical states of light in three-dimensional microwave cavities has emerged as a promising paradigm for continuous-variable quantum information processing. Here we ex…
Fast multi-qubit gates through simultaneous two-qubit gates
Xiu Gu, Jorge Fernández-Pendás, Pontus Vikstål +8
Near-term quantum computers are limited by the decoherence of qubits to only being able to run low-depth quantum circuits with acceptable fidelity. This severely restricts what qua…
Quantum efficiency, purity and stability of a tunable, narrowband microwave single-photon source
Yong Lu, Andreas Bengtsson, Jonathan J. Burnett +7
We demonstrate an on-demand source of microwave single photons with 71--99\% intrinsic quantum efficiency. The source is narrowband (300\unite{kHz}) and tuneable over a 600 MHz ran…
