Getting Started

MonitoredQuantumCircuits.jl is structured around three core components: qubit geometry, circuit construction, and circuit execution. This guide provides a concise overview to help you begin using the framework effectively.

Before proceeding, ensure that MonitoredQuantumCircuits.jl is installed and loaded:

using MonitoredQuantumCircuits

1. Select a Geometry

A Geometry defines the arrangement and connectivity of qubits, typically represented as a graph. Operations can only be applied to qubits that are connected within the chosen geometry. For further details, refer to the Geometries documentation.

To construct a geometry object, use one of the provided constructors. For example:

geometry = HoneycombGeometry(Periodic, 12, 12)

2. Construct a Circuit

A circuit encapsulates the operations applied to the qubits within a given geometry. For more information, see Circuits.

To create a circuit, you may use a predefined constructor:

circuit = MeasurementOnlyKitaev(geometry, px, py, pz; depth=100)

Alternatively, you can build a circuit iteratively by initializing an empty circuit:

circuit = Circuit(geometry)

You may then use the command-line interface to apply operations, or launch the Graphical User Interface (GUI, work in progress):

GUI.CircuitComposer!(circuit)

Once your circuit is complete, compile it for improved performance:

compiled_circuit = compile(circuit)

3. Execute the Circuit

To execute a quantum circuit, first select an appropriate backend. For example, to use a Clifford simulator via QuantumClifford.jl:

simulator = QuantumClifford.TableauSimulator(nQubits(geometry))

Or, for state vector simulation using cuQuantum through Qiskit-Aer:

simulator = Qiskit.GPUStateVectorSimulator()

Execute the compiled circuit on the chosen backend:

execute!(compiled_circuit, simulator)

For additional details, consult the Backends documentation.
