Face colors for faces [0,1,2,3,4,5] are [“yellowgreen”, “yellowgreen”, “tomato”, “tomato”, “yellowgreen”,”yellowgreen”]

Preformatted operators are stored in DiagonalHourGlassTile.op_dict. Keys for op_dict are of the form [p|c]PPPP… where p = pattern and c = copy and P is a Pauli opertor X, Z, Y:

"pXXZZXX" -> #0 face is Pauli('XXX') operator,
             #1 face is Pauli('XXX'),
             #3 face is Pauli('ZZZZ') etc.

Available precomputed operator layouts are:

"pXXZZXX", "pZZXXZZ"

The operator variable may be used to define the operators specifically. The operator must be a list of PauliList objects where each PauliList describes the opertors to be built for the faces as indexed above 0,1,2,3, … If the PauliList contains k Paulis then k operators will be created for the given face.

Parameters:

• origin (np.array) – Coordinates of origin of tile (shell)

• qubit_count – Qubit counter. Defaults to None.

• qubit_data – Qubit data. Defaults to None.

• operators – Operators for tile faces. Defaults to None.

• optype (optional) – Which of the listed opertor mapppings to used. Defaults to “pXXZZXX”.

Raises:

QiskitError – Unsupported operator type

Returns:

Returns a Diagonal Hour Glass tile (shell) with provided origin

Return type:

Shell

Methods

classmethod draw()

Display the tile

Return type:

None
