SupportsCommutators

class SupportsCommutators

Bases: Protocol[T]

A runtime-checkable Protocol indicating support for efficient commutator generation.

Implementation of this protocol requires the three methods below.

static _commutator_(op_a, op_b)

Computes the commutator of two operator instances.

See commutator() for more details.

Parameters:

• op_a (T)

• op_b (T)

Return type:

T

static _anti_commutator_(op_a, op_b)

Computes the anti-commutator of two operator instances.

See anti_commutator() for more details.

Parameters:

• op_a (T)

• op_b (T)

Return type:

T

static _double_commutator_(op_a, op_b, op_c, sign)

Computes the double-commutator of three operator instances.

See double_commutator() for more details.

Parameters:

• op_a (T)

• op_b (T)

• op_c (T)

• sign (bool)

Return type:

T
