The subthreshold issue of fusion-based quantum computing
Matthias C. Löbl, Love A. M. Pettersson, Jan Dragašević +2
Fusion-based quantum architectures are the leading approach to photonic quantum computing. However, the sub-threshold regime, where logical error rates must reach the levels requir…
Breadth-first graph traversal union-find decoder
Matthias C. Löbl, Susan X. Chen, Stefano Paesani +1
Fast decoding algorithms are decisive for real-time quantum error correction and for analyzing properties of error correction codes. Here, we develop variants of the union-find dec…
Structural symmetry-breaking to explain radiative Auger transitions in self-assembled quantum dots
Krzysztof Gawarecki, Clemens Spinnler, Liang Zhai +6
The optical spectrum of a quantum dot is typically dominated by the fundamental transition between the lowest-energy configurations. However, the radiative Auger process can result…

Solid-state quantum dots are promising candidates for efficient light-matter interfaces connecting internal spin degrees of freedom to the states of emitted photons. However, selec…
Radiative Auger Process in the Single-Photon Limit
Matthias C. Löbl, Clemens Spinnler, Alisa Javadi +8
In a multi-electron atom, an excited electron can decay by emitting a photon. Typically, the leftover electrons are in their ground state. In a radiative Auger process, the leftove…
