Parametric two-qubit gates via Landau-Zener interference
Simon Geisert, Albert Hertel, Soeren Ihssen +23
We propose and demonstrate gates between two superconducting qubits based on quantum interference of consecutive Landau-Zener (LZ) transitions. This gate mechanism bridges between…

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…
