Subsystem color code[1,2] 

Also known as Gauge color code.


A subsystem version of the color code. One way to obtain it is by expanding the vertices of a two-colex embedded in a surface of genus \(g\). Vertex expansion consists of spl every vertex into a triangle and splitting every edge into a pair of edges.

  • Color code
  • Honeycomb Floquet code — Both honeycomb and subsystem color codes are generated via periodic sequences of measurements. However, any measurement sequence can be performed on the color code without destroying the logical qubits, while honeycomb codes can be maintained only with specific sequences. Honeycomb codes require a shorter measurement cycle and use fewer qubits at the given code distance [6].
  • Majorana subsystem stabilizer code — The 3D subsystem color code has a Majorana variant which supports a 2D Majorana color code on its surface [7].
  • Quantum pin code — Quantum pin codes have a subsystem version that can be viewed as a generalization of subsystem color codes [8].
