Quantum OpenQASM Assistant is a VS Code extension and Model Context Protocol (MCP) server for IBM Quantum — submit OpenQASM 2.0 circuits to real quantum hardware and simulators from Cursor, VS Code, IBM Bob, and Google Antigravity. Includes Quantum Lab (interactive circuit editor), live job polling, measurement histograms, Bell state / GHZ examples, SamplerV2 REST integration, and one-click MCP setup for AI coding assistants.

Design circuits in Qiskit, export to OpenQASM 2.0, and run on IBM Quantum hardware via MCP or Quantum Lab:
from qiskit import QuantumCircuit, qasm2
qc = QuantumCircuit(2, 2)
qc.h(0)
qc.cx(0, 1)
qc.measure([0, 1], [0, 1])
print(qasm2.dumps(qc)) # → submit via MCP or paste into Quantum LabOPENQASM 2.0;
include "qelib1.inc";
qreg q[2]; creg c[2];
h q[0];
cx q[0],q[1];
measure q[0] -> c[0];
measure q[1] -> c[1];No Qiskit dependency at runtime — the MCP server speaks OpenQASM + IBM Quantum REST directly.
