Minimizing the discrimination time for quantum states of an artificial atom
Ivan Takmakov, Patrick Winkel, Farshad Foroughi +9
Fast discrimination between quantum states of superconducting artificial atoms is an important ingredient for quantum information processing. In circuit quantum electrodynamics, in…
Superconducting granular aluminum resonators resilient to magnetic fields up to 1 Tesla
K. Borisov, D. Rieger, P. Winkel +8
High kinetic inductance materials constitute a valuable resource for superconducting quantum circuits and hybrid architectures. Superconducting granular aluminum (grAl) reaches kin…
State preparation of a fluxonium qubit with feedback from a custom FPGA-based platform
Richard Gebauer, Nick Karcher, Daria Gusenkova +12
We developed a versatile integrated control and readout instrument for experiments with superconducting quantum bits (qubits), based on a field-programmable gate array (FPGA) platf…
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…
Granular aluminum: A superconducting material for high impedance quantum circuits
Lukas Grünhaupt, Martin Spiecker, Daria Gusenkova +8
Superconducting quantum information processing machines are predominantly based on microwave circuits with relatively low characteristic impedance, of about 100 Ohm, and small anha…
An argon ion beam milling process for native layers enabling coherent superconducting contacts
Lukas Grünhaupt, Uwe von Lüpke, Daria Gusenkova +8
We present an argon ion beam milling process to remove the native oxide layer forming on aluminum thin films due to their exposure to atmosphere in between lithographic steps. Our…
