Execution on C12 Quantum Cloud

C12 is building scalable carbon-based quantum computers. Classiq supports execution on C12 QPU-emulators.

​
Configuration

C12 introduces several customizable hardware parameters (Available through SDK only):

​
inilabel

The initial state specified using a binary label format, such as “00”, “01”, etc.

​
inistatevector

The initial state vector for each qubit, provided as a comma-separated list of complex values. Example: “1.+0.j, 0.+0.j, 0.+0.j, 0.+0.j” Note: Either inilabel or inistatevector can be provided but not both.

​
ininoisy

Indicates whether noisy initialization of the circuit should be used.

​
Usage Example

If you are using Classiq IDE, simply choose C12 in the checkbox menu under Execution page.

​
Setting up Backend Preferences

from classiq.execution import C12BackendPreferences
from classiq import ExecutionPreferences, ExecutionSession, synthesize

backend_preferences = C12BackendPreferences(
    backend_name="c12sim-iswap",
    inilabel="00",  # Either inilabel or inistatevector must be provided
    # inistatevector="1.+0.j, 0.+0.j,", # Either inilabel or inistatevector must be provided
    ininoisy=True,
)

execution_preferences = ExecutionPreferences(
    num_shots=1000,
    backend_preferences=backend_preferences,
)

​
Execute with ExecutionSession

Create your model, set execution preferences, synthesize, then run with ExecutionSession: 
quantum_program = synthesize(your_model, preferences=preferences)
quantum_program = set_quantum_program_execution_preferences(
    quantum_program, execution_preferences
)

with ExecutionSession(quantum_program) as session:
    result = session.sample()
