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. The exact representation of the circuit depends on the backend.

To create a circuit, you must first pick a backend. For example a Clifford circuit can be efficiently represented using a stabilizer tableau.

backend = QuantumClifford.TableauSimulator(nqubits::Int)

Now you can apply operations to the circuit using

apply!(backend::Backend, ::Operation, position)

It is best practice, to constructing the circuit in a separate function

function circuit!(::Backend)
    # apply! ...
end

3. Execute the Circuit

To execute the circuit run

execute!(() -> circuit!(backend), ::Backend, post_processing::Function)

where the post_processing function takes the shot index and could compute some property of the circuit.

For additional details, consult the Backends documentation.
