quairkit.core.state.backend.state_vector¶

The source file of the state_vector backend.

class quairkit.core.state.backend.state_vector.PureState(data, sys_dim, system_seq=None, probability=None)¶

The pure state class.

Parameters:¶

data : Tensor¶: tensor array in vector representation for quantum pure state(s).
sys_dim : List[int]¶: a list of dimensions for each system.
system_seq : List[int] | None¶: the system order of this state. Defaults to be from 1 to n.
probability : List[Tensor] | None¶: tensor array for state distributions. Defaults to be 1.

Note

The data is stored in the vector-form with shape \((-1, d)\)
