Industrial 300mm wafer processed spin qubits in natural silicon/silicon-germanium
Thomas Koch, Clement Godfrin, Viktor Adam +11
The realisation of an universal quantum computer will require the operation of thousands to millions of qubits. The possibility of using existing industrial semiconductor fabricati…
Noise reduction by bias cooling in gated Si/SixGe1-x quantum dots
Julian Ferrero, Thomas Koch, Sonja Vogel +7
Silicon-Germanium heterostructures are a promising quantum circuit platform, but crucial aspects as the long-term charge dynamics and cooldown-to-cooldown variations are still wide…
Non-degenerate parametric amplifiers based on dispersion engineered Josephson junction arrays
Patrick Winkel, Ivan Takmakov, Dennis Rieger +12
Determining the state of a qubit on a timescale much shorter than its relaxation time is an essential requirement for quantum information processing. With the aid of a new type of…
Phonon traps reduce the quasiparticle density in superconducting circuits
Fabio Henriques, Francesco Valenti, Thibault Charpentier +14
Out of equilibrium quasiparticles (QPs) are one of the main sources of decoherence in superconducting quantum circuits, and are particularly detrimental in devices with high kineti…
