Asymmetric node placement in fiber-based quantum networks

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Guus Avis, Robert Knegjens, Anders S. Sørensen, Stephanie Wehner, | Summary: Restrictions imposed by existing infrastructure can make it hard to ensure an even spacing between the nodes of future fiber-based quantum networks. We here investigate the negative effects of asymmetric node placement by considering separately the […]

Germanium wafers for strained quantum wells with low disorder

Kavli Affiliate: Menno Veldhorst | First 5 Authors: Lucas E. A. Stehouwer, Alberto Tosato, Davide Degli Esposti, Davide Costa, Menno Veldhorst | Summary: We grow strained Ge/SiGe heterostructures by reduced-pressure chemical vapor deposition on 100 mm Ge wafers. The use of Ge wafers as substrates for epitaxy enables high-quality Ge-rich SiGe strain-relaxed buffers with a […]

Enhanced sensitivity and tunability of thermomechanical resonance near the buckling bifurcation

Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Hanqing Liu, Gabriele Baglioni, Carla B. Constant, Herre S. J. van der Zant, Peter G. Steeneken | Summary: The high susceptibility of ultrathin two-dimensional (2D) material resonators to force and temperature makes them ideal systems for sensing applications and exploring thermomechanical coupling. Although […]

All-microwave and low-cost Lamb shift engineering for a fixed frequency multi-level superconducting qubit

Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Gary A. Steele, , , | Summary: It is known that the quantum nature of the electromagnetic vacuum is responsible for the Lamb shift, which is a crucial phenomenon in quantum electrodynamics (QED). In circuit QED, the readout or bus resonators that are dispersively […]
