paddle_quantum.locc.locc_state

The source file of the LoccState class.

class paddle_quantum.locc.locc_state.LoccState(data=None, prob=None, measured_result=None, num_qubits=None, backend=None, dtype=None)

Bases: State

An LOCC state in LOCCNet.

We care not only about the quantum state in LOCC, but also about the probability of getting it and the corresponding measurement result. Therefore, this class contains three attributes: quantum state data, the probability of getting this state prob, and the measurement result leading to this state, namely measured_result.

Parameters:

  • data (Tensor) – Matrix form of the quantum state of this LoccState. Defaults to None.

  • prob (Tensor) – Probability of getting this quantum state.. Defaults to None.

  • measured_result (str) – Measurement result leading to this quantum state. Defaults to None.

  • num_qubits (int | None) – Total number of qubits. Defaults to None.

  • backend (Backend | None) – Backend of Paddle Quantum. Defaults to None.

  • dtype (str | None) – Type of data. Defaults to None.
