Spin and Majorana qubits

Invitation to Seminar Talk
Spin and Majorana qubits
Ferdinand Kuemmeth
Niels Bohr Institute, Center for Quantum Devices, University of Copenhagen
Host: Giorgos Katsaros
Modern computers store information classically, using the charge of electrons, and
quantum effects remain a detail rather than a resource. Even in today's tiniest
transistors maintaining coherent quantum superpositions of charge states is a
fruitless challenge. At sufficiently low temperatures, however, new degrees of
freedom emerge in semiconducting-superconducting devices that are neutral,
coherent, and useful for processing quantum information. Curiously, these neutral
qubit encodings allow for coherent control by local voltage pulses - a paradoxical
property on first thought, but on second thought offering a powerful and scalable
paradigm for the realization of quantum computers. In this talk I will illustrate how
these concepts can be harnessed in the contexts of semiconducting spin qubits and
topological superconducting nanowires, including an overview of our recent
experimental results.
