Emergence of Bogoliubov Fermi Surfaces in hybrid Al/InAs heterostructures

S. Feyrer, V. Dimic, I. Lobato +15

We investigate the microwave electrodynamics of a proximitized two-dimensional electron gas in hybrid superconductor/semiconductor heterostructures. Using lumped-element resonators…

20 Second Parity Lifetime in an InAs--Pb Tetron Device

Morteza Aghaee, Zulfi Alam, Mariusz Andrzejczuk +162

A central promise of topological quantum computing is that increasing the excitation gap improves device performance significantly. Here, we experimentally validate this principle…

Roadmap to fault tolerant quantum computation using topological qubit arrays

David Aasen, Morteza Aghaee, Zulfi Alam +179

We describe a concrete device roadmap towards a fault-tolerant quantum computing architecture based on noise-resilient, topologically protected Majorana-based qubits. Our roadmap e…
