dwave-gate 0.5.0

dwave-gate

dwave-gate provides the functionality for generating quantum circuit description language (QCDL) programs. QCDL is an embedded domain-specific language (DSL) that uses Python as its host language, allowing you to interleave classical Python preprocessing with quantum gate operations. Programs are defined with the @qcdl decorator, which converts an ordinary Python function into a QCDL program generator that accepts qubit arguments and returns a dictionary suitable for submission to compiler or simulator services.

The following example creates a Bell state circuit, producing a dictionary that can be passed to a compiler or simulator:

from dwave.gate.qcdl import qcdl
from dwave.gate.qcdl.operations import cx, h, measure

@qcdl(num_qubits=2)
def main(q0, q1):
    h(q0)        # Hadamard gate on q0
    cx(q0, q1)   # CNOT with q0 as control, q1 as target
    measure(q0)
    measure(q1)

qcdl_program = main()

To run the program on a solver, use the LeapQCDLSimulator to locate a solver that supports QCDL and submit the QCDL program via run:

from dwave.gate.leap import LeapQCDLSimulator

simulator = LeapQCDLSimulator()
future = simulator.run(qcdl_program, shots=3)
result = future.result().result

Access measurements and sample counts by calling result.measurements or result.get_counts() respectively.
