Anomalous periodicity and parafermion hybridization in superconducting qubits
Alessio Calzona, Matteo Carrega, Luca Chirolli
Topological quantum computation relies on a protected degenerate subspace enabling complicated operations in a noise-resilient way. To this end, hybrid platforms based on non-Abeli…
Multi-mode architectures for noise-resilient superconducting qubits
Alessio Calzona, Matteo Carrega
Great interest revolves around the development of new strategies to efficiently store and manipulate quantum information in a robust and decoherence-free fashion. Several proposals…
Quench-Probe Setup as Analyzer of Fractionalized Entanglement Spreading
Nicolas P. Bauer, Jan Carl Budich, Björn Trauzettel +1
We propose a novel spatially inhomogeneous setup for revealing quench-induced fractionalized excitations in entanglement dynamics. In this quench-probe setting, the region undergoi…
Optimization of Richardson extrapolation for quantum error mitigation
Michael Krebsbach, Björn Trauzettel, Alessio Calzona
Quantum error mitigation is a key concept for the development of practical applications based on current noisy intermediate scale quantum (NISQ) devices. One of the most promising…
Anomalous flux periodicity in proximitised quantum spin Hall constrictions
Lucia Vigliotti, Alessio Calzona, Björn Trauzettel +2
We theoretically analyse a long constriction between the helical edge states of a two-dimensional topological insulator. The constriction is laterally tunnel-coupled to two superco…
