Quantum Coherence in Superconducting Vortex States

Ameya Nambisan, Simon Günzler, Dennis Rieger +13

Abrikosov vortices, where the superconducting gap is completely suppressed in the core, are dissipative, semi-classical entities that impact applications from high-current-density…

On-chip stencil lithography for superconducting qubits

Roudy Hanna, Sören Ihssen, Simon Geisert +22

Improvements in circuit design and more recently in materials and surface cleaning have contributed to a rapid development of coherent superconducting qubits. However, organic resi…

High Impedance Granular Aluminum Ring Resonators

Mahya Khorramshahi, Martin Spiecker, Patrick Paluch +10

Superconducting inductors with impedance surpassing the resistance quantum, i.e., superinductors, are important for quantum technologies because they enable the development of prot…

Offset Charge Dependence of Measurement-Induced Transitions in Transmons

Mathieu Féchant, Marie Frédérique Dumas, Denis Bénâtre +9

A key challenge in achieving scalable fault tolerance in superconducting quantum processors is readout fidelity, which lags behind one- and two-qubit gate fidelity. A major limitat…

Low crosstalk modular flip-chip architecture for coupled superconducting qubits

Soeren Ihssen, Simon Geisert, Gabriel Jauma +10

We present a flip-chip architecture for an array of coupled superconducting qubits, in which circuit components reside inside individual microwave enclosures. In contrast to other…
