Pattern data structure

graphix.command module

This module defines standard data structure for pattern commands.

class graphix.command.CommandKind(value)

An enumeration.

class graphix.command.N(*, kind: CommandKind = CommandKind.N, node: int)

Preparation command.

class graphix.command.M(*, kind: CommandKind = CommandKind.M, node: int, plane: Plane = Plane.XY, angle: float = 0.0, s_domain: list[int] = [], t_domain: list[int] = [], vop: int = 0)

Measurement command. By default the plane is set to ‘XY’, the angle to 0, empty domains and identity vop.

class graphix.command.E(*, kind: CommandKind = CommandKind.E, nodes: tuple[int, int])

Entanglement command.

class graphix.command.C(*, kind: CommandKind = CommandKind.C, node: int, cliff_index: int)

Clifford command.

class graphix.command.X(*, kind: CommandKind = CommandKind.X, node: int, domain: list[int] = [])

X correction command.

class graphix.command.Z(*, kind: CommandKind = CommandKind.Z, node: int, domain: list[int] = [])

Z correction command.

graphix.pauli module

This module defines standard data structure for Pauli operators, measurement planes and their transformations.

class graphix.pauli.Plane(value)

An enumeration.

class graphix.pauli.Pauli(symbol: IXYZ, unit: ComplexUnit)

Pauli gate: u * {I, X, Y, Z} where u is a complex unit

Pauli gates can be multiplied with other Pauli gates (with @), with complex units and unit constants (with *), and can be negated.

__init__(symbol: IXYZ, unit: ComplexUnit)

property matrix: ndarray

Return the matrix of the Pauli gate.

class graphix.pauli.MeasureUpdate(*, new_plane: Plane, coeff: int, add_term: float)

graphix.instruction module

This module defines standard data structure for gate seqence (circuit model) used for graphix.transpiler.Circuit.

class graphix.instruction.InstructionKind(value)

An enumeration.

class graphix.instruction.RX(*, kind: InstructionKind = InstructionKind.RX, meas_index: int = None, target: int, angle: float)

X rotation circuit instruction.

class graphix.instruction.RZ(*, kind: InstructionKind = InstructionKind.RZ, meas_index: int = None, target: int, angle: float)
