circuit | IBM Quantum Documentation
WEBIn Qiskit, a quantum circuit is represented by the QuantumCircuit class. Below is an example of a quantum circuit that makes a three-qubit Greenberger–Horne–Zeilinger (GHZ) state defined as: ∣ ψ = ( + ) / |\psi\rangle = \left ( |000\rangle + |111\rangle \right) / \sqrt {2} ∣ψ =(∣000 +∣111 )/2.
Barrier - IBM Quantum Documentation
WEBA barrier is a visual indicator of the grouping of a circuit section. It also acts as a directive for circuit compilation to separate pieces of a circuit so that any optimizations or re-writes are constrained to only act between barriers.
What is a "barrier" in Qiskit circuits?
WEBThe barrier acts as a directive for circuit compilation to separate pieces of a circuit so that any optimizations or re-writes are constrained to only act between barriers (and if there are no barriers they act on the whole circuit).

WEBCreating a barrier. The barrier() method places a barrier on a circuit (shown in Figure 1-4), providing both visual and functional separation between gates on a quantum circuit.
qiskit.pulse.builder.barrier — Qiskit 0.32.1 documentation
WEBqiskit.pulse.builder.barrier¶ barrier (* channels_or_qubits, name = None) [source] ¶ Barrier directive for a set of channels and qubits. This directive prevents the compiler from moving instructions across the barrier. Consider the case where we want to enforce that one pulse happens after another on separate channels, this can be done with:

Running Quantum Circuits | IBM Quantum Learning
WEBQiskit patterns are a conceptual framework allowing users to run quantum workloads by implementing certain steps with modular tooling. This allows quantum computing tasks to be performed by a powerful heterogenous (CPU/GPU/QPU) computing infrastructure.
