- ===============
- Getting Started
- ===============
- When using this library, you will most likely be using the :class:`~qiskit.State` class.
- This class represents the state of a quantum register.
- Using this class you can apply gates to the register, measure, get the state vector and things like that.
- To run a simple quantum circuit, you can use something like this,
- .. code-block:: python
- # Import QCGPU
- import qcgpu
- # Create a new quantum register with 2 qubits
- register = qcgpu.State(2)
- # Apply a hadamard (H) gate to the first qubit.
- # You should note that the qubits are zero indexed
- register.h(0)
- # Add a controlled not (CNOT/CX) gate, with the control as
- # the first qubit and target as the second.
- # The register will now be in the bell state.
- register.cx(0, 1)
- # Perform a measurement with 1000 samples
- results = register.measure(samples=1000)
- # Show the results
- print(results)
- The output of a measurement gives a dictionary of measurement outcomes,
- along with how often they occurred.
- .. code-block:: python
- {'00': 486, '11': 514}
- There are a few different ways to do things using QCGPU,
- so you should check out the rest of the documentation too
