Release Note

Improvements

• Accelerated circuit executions, providing 2-4 times speed-up compared to the previous version. Specifically, over 10 times speed-up for specific quantum neural network models.

New Features

• paddle_quantum.gate:
• Gate is now a child class of paddle_quantum.channel.Channel, and hence inherits most functionalities from the channel module, such as its Choi representation Gate.choi_repr.
• New module matrix: provides user access to the matrices of gates in Paddle Quantum.
• New gate ParamOracle: provides user access to customized parameterized gates.
• paddle_quantum.qinfo:
• New function pauli_str_convertor: Concatenate the input observable with coefficient 1.
• paddle_quantum.loss.ExpecVal:
• Now ExpecVal.forward() can return the decomposed expectation value by setting decompose=True.
• paddle_quantum.state.State:
• Now State.measure() can record the result in each shot by setting record=True.
