Specs, examples and tools for the OpenQASM 2.0 intermediate representation.

On this repository you'll find all the documentation related to OpenQASM and some useful OpenQASM examples.

The language documentation is available here.

The examples can be found under the examples folder.

The examples that cannot necessarily be executed on any existing hardware. You can still run these circuits in a simulator.

• adder.qasm: Adds two four-bit numbers.
• bigadder.qasm: Quantum ripple-carry adder. 8-bit adder made out of 2 4-bit adders from adder.qasm.
• inverseqft1.qasm: Inverse quantum Fourier transform using 4 qubits.
• inverseqft2.qasm: Another version of the inverse quantum Fourier transform using 4 qubits.
• ipea_3_pi_8.qasm: 4-bit Iterative Phase Estimation algorithm for phase 3\pi/8 using two qubits.ss
• pea_3_pi_8.qasm: 4-bit Phase Estimation algorithm for a phase 3\pi/8 using 5 qubits.
• qec.qasm: Repetition code to correct quantum errors.
• qft.qasm: Quantum Fourier transform on 4 qubits.
• qpt.qasm: Quantum Process Tomography example.
• rb.qasm: Example of a single instance of two-qubits randomized benchmarking.
• teleport.qasm: Quantum Teleportation example.
• teleportv2.qasm: Quantum Teleportation example (one classical register).
• W-state.qasm: Generating a 3-qubit W-state using Toffoli gates

Examples of invalid code:

• invalid_missing_semicolon.qasm
• invalid_gate_no_found.qasm
