“A quantum code for which there existed a universal set of encoded gates each transversal in isolation would be extremely useful.” -- Eastin & Knill arxiv.org/abs/2610.06730

Qubit CSS codes with Universal Transversal Gates
The Eastin-Knill theorem rules out a universal set of transversal logical gates on any code that detects single-qubit errors. The theorem constrains one partition of the qubits at a time. We show that...
