Exponential protection of zero modes in Majorana islands

Autor: Thomas Sand Jespersen, Charles Marcus, Jesper Nygård, Peter Krogstrup, Andrew Higginbotham, Ferdinand Kuemmeth, Morten Hannibal Madsen, S. M. Albrecht

Publikováno v: Nature. 531:206-209

Majorana zero modes are quasiparticle excitations in condensed matter systems that have been proposed as building blocks of fault-tolerant quantum computers [1]. They are expected to exhibit non-Abelian particle statistics, in contrast to the usual s

Grove-Rasmussen, K, Steffensen, G O, Jellinggaard, A R, Madsen, M H, Žitko, R, Paaske, J & Nygård, J 2018, ' Yu-Shiba-Rusinov screening of spins in double quantum dots ', Nature Communications, vol. 9, 2376 . https://doi.org/10.1038/s41467-018-04683-x

A magnetic impurity coupled to a superconductor gives rise to a Yu-Shiba-Rusinov (YSR) state inside the superconducting energy gap. With increasing exchange coupling the excitation energy of this state eventually crosses zero and the system switches

Semiconducting nanowires (NWs) are a versatile, highly tunable material platform at the heart of many new developments in nanoscale and quantum physics. Here, we demonstrate charge pumping, i.e., the controlled transport of individual electrons throu

Study on Microgratings Using Imaging, Spectroscopic, and Fourier Lens Scatterometry

Autor: Jan F J⊘rgensen, Jonas Skovlund Madsen, Deepak Dwarakanath, Poul Erik Hansen, Brian Bilenberg, Morten Hannibal Madsen, Jesper Nygård, Pierre Boher

Publikováno v: Journal of Micro and Nano-Manufacturing. 5

With new fabrication methods for mass production of nanotextured samples, there is an increasing demand for new characterization methods. Conventional microscopes are either too slow and/or too sensitive to vibrations. Scatterometry is a good candida
