RPNGDescription#

class tqec.plaquette.RPNGDescription(corners, ancilla=RG(r=<PauliBasis.X: 'x'>, g=<PauliBasis.X: 'x'>))[source]#

Bases: object

Organize the description of a plaquette in RPNG format

The corners of the square plaquette are listed following the order: top-left, top-right, bottom-left, bottom-right. This forms a Z-shaped path on the plaquette corners:

+------------+
| 1 -----> 2 |
|        /   |
|      /     |
|    ∟       |
| 3 -----> 4 |
+------------+

If the ancilla RG description is not specified, it is assumed ‘xx’

Parameters:

corners (tuple[RPNG, RPNG, RPNG, RPNG])
ancilla (RG)

corners#

one RPNG description for each of the four corners of the plaquette.

Type:: tuple[tqec.plaquette.rpng.rpng.RPNG, tqec.plaquette.rpng.rpng.RPNG, tqec.plaquette.rpng.rpng.RPNG, tqec.plaquette.rpng.rpng.RPNG]

ancilla#

RG description of the syndrome qubit.

Type:: tqec.plaquette.rpng.rpng.RG
