Capped color code (CCC)[1]
Description
A non-geometrically local subsystem color code consisting of two layers of 2D color code stacked together and topped (or capped) by a single qubit. Gauge fixing yields two types of codes, capped color codes in H or T form. Layers of 2D color codes can also be stacked together in a recursive construction, yielding recursive capped color codes (RCCCs).
Transversal Gates
Capped color codes in H (T) form admit a transversal Hadamard (T) gate.
Fault Tolerance
Fault-tolerant syndrome extraction and error correction for capped color codes in H form [1].Fault-tolerant T gate implementation [1].
