Majorana box qubits
Stephan Plugge, Asbjørn Rasmussen, Reinhold Egger +1
Quantum information protected by the topology of the storage medium is expected to exhibit long coherence times. Another feature are topologically protected gates generated through…
Josephson effects in twisted cuprate bilayers
Tarun Tummuru, Stephan Plugge, Marcel Franz
Twisted bilayers of high- cuprate superconductors have been argued to form topological phases with spontaneously broken time reversal symmetry for certain twist ang…
Majorana bound states in vortex lattices on iron-based superconductors
Vedangi Pathak, Stephan Plugge, Marcel Franz
Majorana quasi-particles may arise as zero-energy bound states in vortices on the surface of a topological insulator that is proximitized by a conventional superconductor. Such a s…
Traversable wormhole and Hawking-Page transition in coupled complex SYK models
Sharmistha Sahoo, Ãtienne Lantagne-Hurtubise, Stephan Plugge +1
Recent work has shown that coupling two identical Sachdev-Ye-Kitaev (SYK) models can realize a phase of matter that is holographically dual to an eternal traversable wormhole. This…
Josephson diode effects in twisted nodal superconductors
Pavel A. Volkov, Ãtienne Lantagne-Hurtubise, Tarun Tummuru +3
Recent Josephson tunneling experiments on twisted flakes of high- cuprate superconductor BiSrCaCuO revealed a non-reciprocal behavior of the critical inter…
Diagnosing quantum chaos in many-body systems using entanglement as a resource
Ãtienne Lantagne-Hurtubise, Stephan Plugge, Oguzhan Can +1
Classical chaotic systems exhibit exponentially diverging trajectories due to small differences in their initial state. The analogous diagnostic in quantum many-body systems is an…
