MindQuantum adds the following quantum channels for quantum noise simulation
PauliChannel: Pauli channelBitFlipChannel: bit-flip channelPhaseFlipChannel: phase-flip channelBitPhaseFlipChannel: bit-phase flip channelDepolarizingChannel: depolarized channel
We unified the abbreviations of some nouns in MindQuantum.

The quantum neural network API was redesigned in this version. From now on, we can easily build a hybrid quantum neural network with the help of Simulator in PYNATIVE_MODE.
The following API was removed.
generate_pqc_operatorPQCMindQuantumLayergenerate_evolution_operatorEvolutionMindQuantumAnsatzOnlyLayerMindQuantumAnsatzOnlyOperator
The new API was shown as below.
MQOpsMQN2OpsMQAnsatzOnlyOpsMQN2AnsatzOnlyOpsMQEncoderOnlyOpsMQN2EncoderOnlyOpsMQLayerMQN2LayerMQAnsatzOnlyLayerMQN2AnsatzOnlyLayer
The above modules are placed in mindquantum.framework.
Due to the duplication of functions, we deleted some APIs.
mindquantum.circuit.StateEvolution
The following APIs have been remoted.
mindquantum.core.operators.Hamiltonian.mindspore_datamindquantum.core.operators.Projector.mindspore_datamindquantum.core.circuit.Circuit.mindspore_datamindquantum.core.parameterresolver.ParameterResolver.mindspore_data
New gates are shown as below.
mindquantum.core.gates.SGatemindquantum.core.gates.TGate
Measurement on certain qubits are now supported. The related APIs are shown as below.
mindquantum.core.gates.Measuremindquantum.core.gates.MeasureResult
QASM is now supported.
mindquantum.io.OpenQASMmindquantum.io.random_hiqasmmindquantum.io.HiQASM
Simulator is now separated from MindSpore backend. Now you can easily to use a simulator.
mindquantum.simulator.Simulator
For improving MindQuantum's package structure, we did some refactoring on MindQuantum.
