Reducing intrinsic loss in superconducting resonators by surface treatment and deep etching of silicon substrates
A. Bruno, G. de Lange, S. Asaad +3
We present microwave-frequency NbTiN resonators on silicon, systematically achieving internal quality factors above 1 M in the quantum regime. We use two techniques to reduce losse…

Detecting bit-flip errors in a logical qubit using stabilizer measurements
D. Ristè, S. Poletto, M. -Z. Huang +4
Quantum data is susceptible to decoherence induced by the environment and to errors in the hardware processing it. A future fault-tolerant quantum computer will use quantum error c…

Towards high mobility InSb nanowire devices
Önder Gül, David J. van Woerkom, Ilse van Weperen +4
We study the low-temperature electron mobility of InSb nanowires. We extract the mobility at 4.2 Kelvin by means of field effect transport measurements using a model consisting of…
