Q-CTRL’s Multi-Qubit Circuit Simulator
Practice with up to 5 simulated qubits.
In addition to its previously released single-qubit circuit simulator, Q-CTRL’s Black Opal now includes a multi-qubit circuit simulator with up to five simulated qubits. Although you don’t run your circuits like you would with, let’s say, Qiskit’s simulator, you can analyze your results via circle notation, which is explained in the tutorial section of Black Opal.
One uncommon feature (you can do this with Quirk) is you can step through your circuit and observe how each operation(s) affects the output. Even more interestingly, you can alternate stepping backward and forward for closer scrutiny. And, possibly a unique feature, you can drag the slider anywhere in the circuit and observe transitions in progress.
The greatest value of both the single-qubit and multi-qubit playgrounds is, obviously, as a complement to the tutorials. It’s one thing to check your learning, but you should develop a curiosity as to how gates can work together as parts of algorithms. The playgrounds help you to satisfy that curiosity. “What if I try this?” And, “what if I try that?” And, if you forget something, there are links back to the appropriate tutorial modules.
Stay tuned for information about Black Opal’s upcoming QASM (Quantum Assembly Language) sandbox.
