An angular momentum approach to quantum insertion errors
Lewis Bulled, Yingkai Ouyang
Quantum insertion errors are a class of errors that increase the number of qubits in a quantum system. Despite a wealth of research on classical insertion errors, there has been li…

Measurement-free code-switching for low overhead quantum computation using permutation invariant codes
Yingkai Ouyang, Yumang Jing, Gavin K. Brennen
Transversal gates on quantum error correction codes have been a promising approach for fault-tolerant quantum computing, but are limited by the Eastin-Knill no-go theorem. Existing…
