A Practical Guide for Building Superconducting Quantum Devices
- 19 November 2021
I’m very excited that our tutorial on cQED, the technology behind superconducting qubits, got published in PRX Quantum today! I hope this work will make it easier for anyone looking to get into this fascinating field.
Accelerating quantum computer developments
- 21 July 2021
With Orange Quantum Systems, and our partners in the Dutch Quantum ecosystem we have published a paper in the special quantum industry issue of EPJ Quantum Technology on accelerating the development of quantum computers. In this paper, we present the product development approach and roadmap for quantum computers, based on superconducting circuits as an example.

Cryoscope featured on the cover of Applied Physics Letters
- 03 February 2020
Our paper presenting Cryoscope recently got published and is featured on the cover of Applied Physics Letters. Cryoscope is an in-situ technique which uses a qubit to accurately sample the flux pulses used to dynamically control its frequency. This measurement is key for determining the linear-dynamical distortion on the flux control line and later correcting it, as needed for high-fidelity two-qubit gates.
Net-Zero two-qubit gate published in Physical Review Letters
- 18 September 2019
We have recently developed a new type of conditional-phase gate for transmon qubits providing several key improvements over standard flux-pulsing-based versions. The Net-Zero gate uses “leakage interference” to minimize leakage to non-computational states. The zero-average, bipolar shape of the pulse makes the gate robust to long timescale distortions in the flux control line and additionally provides an echo effect. We demonstrate a state-of-the-art conditional-phase gate of duration 40 ns achieving 99.1% fidelity and 0.1% leakage.
