Subsystem self-correction of the GKP qubit
Brian Chung Hang Cheung, Lasse Bjørn Kristensen, Frederik Nathan +1
Passive quantum error correction, also known as self-correction, is a holy grail in quantum information science. Recent theoretical advances suggest that the Gottesman-Kitaev-Presk…

Majorana fermions and quantum information with fractional topology and disorder
Ephraim Bernhardt, Brian Chung Hang Cheung, Karyn Le Hur
The quest to identify and observe Majorana fermions in physics and condensed-matter systems remains an important challenge. Here, we introduce a qubit (spin-) from the occurre…

Quantum nonlinear spectroscopy via correlations of weak Faraday-rotation measurements
Brian Chung Hang Cheung, Ren-Bao Liu
The correlations of fluctuations are key to studying fundamental quantum physics and quantum many-body dynamics. They are also useful information for understanding and combating de…
