MindQuantum 0.9.11 Release Notes
Major Feature and Improvements
Gates
- [STABLE]
Arbitrary axis rotation
: New single-qubit gates for arbitrary axis rotation on the Bloch sphereRn
。
- [STABLE]
matrix
: The quantum gate supports retrieving its complete matrix representation by using the interface and specifying the parameter full=True
. This matrix representation is influenced by the target qubit and the control qubit, if applicable.
- [STABLE]
Terminal relaxation channel
: Add ThermalRelaxationChannel.
- [Alpha]
Quantum measurement
: The measurement gate now supports qubit reset functionality, allowing the measured quantum state to be reset to the |0⟩ state or the |1⟩ state. The execution speed of the measurement gate has been optimized for improved performance.
- [STABLE]
RotPauliString
: Add arbitrary pauli string rotation gate.
- [STABLE]
GroupedPauli
: Add Pauli combination gate. This gate allows for faster execution compared to individually applying single Pauli gates.
- [STABLE]
GroupedPauliChannel
: Add Pauli combination channel. This channel allows for faster execution compared to applying Pauli channels individually.
- [STABLE]
SX
: Add sqrt X gate.
- [STABLE]
Givens
: Add Givens rotation gate.
Circuit
- [STABLE]
summary
: The summary information of the quantum circuit displayed through this interface will be presented in a table format, making it more visually appealing and straightforward.
- [STABLE]
svg
: Scaling the svg of quantum circuit by setting scale
of this API.
- [STABLE]
openqasm
: Directly convert quantum circuit to openqasm
or convert openqasm
to a mindquantum circuit.
ParameterResolver
Ansatz
Device
Simulator
- [STABLE]
sampling
: Improve the sampling speed for quantum circuit without noise and all measurement only at end.
utils
Algorithm
- [Alpha]
MQSABRE
: A new qubit mapping algorithm that enable to set fidelity of quantum gate.
