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…
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…
Granular Aluminum Parametric Amplifier for Low-Noise Measurements in Tesla Fields
Nicolas Zapata, Ivan Takmakov, Simon Günzler +8
Josephson junction parametric amplifiers have become essential tools for microwave quantum circuit readout with minimal added noise. Even after improving at an impressive rate in t…
Fano Interference in Microwave Resonator Measurements
D. Rieger, S. Günzler, M. Spiecker +3
Resonator measurements are a simple but powerful tool to characterize a material's microwave response. The losses of a resonant mode are quantified by its internal quality factor $…
