OpenConvertors

OpenConvertors are used to implement the conversion of the data model of the circuit. It should be noted that:

When using the converter, the modules won't be automatically called.
The converter supports some quantum gate operations, please refer to the following instructions for details.
The converter does not support subroutines. When there are subroutines in the circuit, you need to call the UnrollProcedureModule module to decompose.

Circuit

Run the following code to get Circuit, namely PBProgram circuit model, also known as QCompute circuit model.

from QCompute import *
from pprint import pprint
from QCompute.Define import Settings
Settings.outputInfo = False

env = QEnv()

q = env.Q.createList(2)

X(q[0])
CX(q[0], q[1])
MeasureZ(*env.Q.toListPair())

# Generate PBProgram and output
env.publish()
pprint(env.program)

DrawConsole

The QCompute SDK provides a one-way converter for implementing Circuit to DrawConsole.

from QCompute import *
from pprint import pprint
from QCompute.Define import Settings
Settings.outputInfo = False

env = QEnv()

q = env.Q.createList(2)

X(q[0])
CX(q[0], q[1])
MeasureZ(*env.Q.toListPair())

# Generate PBProgram
env.publish()

# Convert PBProgram to DrawConsole and output
DrawConsole = CircuitToDrawConsole().convert(env.program)
pprint(DrawConsole)

InternalStruct

The QCompute SDK provides bidirectional converters for implementing Circuit and InternalStruct.

from QCompute import *
from pprint import pprint
from QCompute.Define import Settings
Settings.outputInfo = False

env = QEnv()

q = env.Q.createList(2)

X(q[0])
CX(q[0], q[1])
MeasureZ(*env.Q.toListPair())

# Generate PBProgram
env.publish()
pprint(env.program)

# Convert PBProgram to InternalStruct and output
circuitLineList = CircuitToInternalStruct().convert(env.program.body.circuit)
pprint(circuitLineList)

# Convert InternalStruct to PBProgram and output
circuit = InternalStructToCircuit().convert(circuitLineList)
pprint(circuit)

JSON

The QCompute SDK provides bidirectional converters for implementing Circuit and JSON circuit models.

from QCompute import *
from pprint import pprint
from QCompute.Define import Settings
Settings.outputInfo = False

env = QEnv()

q = env.Q.createList(2)

X(q[0])
CX(q[0], q[1])
MeasureZ(*env.Q.toListPair())

# Generate PBProgram
env.publish()

# Convert PBProgram to JSON and output
jsonStr = CircuitToJson().convert(env.program)
pprint(jsonStr)

# Convert JSON to PBProgram and output
circuit = JsonToCircuit().convert(jsonStr)
pprint(circuit)

QASM

The QCompute SDK provides bidirectional converters for implementing Circuit and QASM circuit models.

from QCompute import *
from pprint import pprint
from QCompute.Define import Settings
Settings.outputInfo = False

env = QEnv()

q = env.Q.createList(2)

X(q[0])
CX(q[0], q[1])
MeasureZ(*env.Q.toListPair())

# Generate PBProgram
env.publish()

# Convert PBProgram to QASM and output
qasmStr = CircuitToQasm().convert(env.program)
pprint(qasmStr)

# Convert QASM to PBProgram and output
circuit = QasmToCircuit().convert(qasmStr)
pprint(circuit)

Qobj

The QCompute SDK provides a one-way converter for implementing Circuit to the Qobj circuit model used by the third-party open source simulator Aer.

from QCompute import *
from pprint import pprint
from QCompute.Define import Settings
Settings.outputInfo = False

env = QEnv()

q = env.Q.createList(2)

X(q[0])
CX(q[0], q[1])
MeasureZ(*env.Q.toListPair())

# Generate PBProgram
env.publish()

# Convert PBProgram to Qobj and output
qobj = CircuitToQobj().convert(env.program, 1024)
pprint(qobj)

IonQ

The ConvertorIonQ is used to realize bidirectional conversion of QCompute circuit model to IonQ circuit model.

from QCompute import *
from pprint import pprint
from QCompute.Define import Settings
Settings.outputInfo = False

env = QEnv()

q = env.Q.createList(2)

X(q[0])
CX(q[0], q[1])
MeasureZ(*env.Q.toListPair())

# Generate PBProgram
env.publish()

# Convert PBProgram to IonQ-JSON and output
ionq_program = CircuitToIonQ().convert(env.program)
pprint(ionq_program)

# Convert IonQ-JSON to PBProgram and output
circuit = IonQToCircuit().convert(ionq_program)
pprint(circuit)
