Niobium Titanium Nitride as a High Tensile Stress Material for Nanomechanics
Korbinian Rubenbauer, Burak E. Bülbüloglu, Thomas Luschmann +6
Over the past decades, high-coherence mechanical resonators have been continuously pushed to new limits, using techniques such as dissipation dilution and clamp-tapering to enhance…
Multi-cavity strong coupling to an electron spin ensemble: spectral and dark-state signatures
P. Oehrl, B. Pérez González, A. Dunaev +5
Spin ensembles are considered as potential candidates for quantum memory and quantum enhanced sensing applications. Here, we explore the controlled coupling of multiple superconduc…
On-chip Dicke-type magnon polaritons in the ultrastrong coupling regime via spatially separated nanomagnets
Shugo Yoshii, Manuel Müller, Ryo Ohshima +4
Quantum electrodynamics lies at the heart of hybrid quantum systems essential for future technologies. The thermodynamic limit of the Dicke model, a fundamental model describing th…
Niobium Air Bridges as Low-Loss Components for Superconducting Quantum Hardware
N. Bruckmoser, L. Koch, I. Tsitsilin +12
Scaling up superconducting quantum processors requires a high routing density for readout and control lines, relying on low-loss interconnects to maintain design flexibility and de…
