Quantum Computing Napoli – QCN
Our facility
Oxford Instruments Triton 400 (nominal base temperature of 7 mK): Cryogen – free dilution refrigerator equipped with two main sample stages: one cold – finger dedicated to low – noise/ filtered transport measurements in a DC environment and one dedicated to RF experiments. DC setup: 4 – contact current – polarized setup (24 TWP filtered current/ voltage cryo – lines + 24 TWP partially filtered current/ voltage cryo – lines) to measure up to 6 samples at once. RF setup: 12 RF attenuated / filtered input lines+2 RF amplified (HEMT@ 4 K) output lines; sample package to measure up to 5 tunable transmon qubits simultaneously + thermally anchored bracket for TWPA and microwave superconducting devices characterization. A wide range of room-temperature electronic instruments completes this system.
Our experiments
The Triton system is currently used for simultaneous experiments on superconducting quantum prototypal devices and for fundamental physics research activities: from the characterization and analysis of the physical processes in Josephson junctions with conventional or unconventional properties, up to the analysis and diagnostic of quantum processing units involving few qubits at a time, and cryogenic superconducting microwave components. We here ran in time several experiments tailored to address collaborative projects and to test home-made superconducting quantum chip designs.
