QNT Quantum Lab Simulator
SIMULATOR Runs on your device. Not a real quantum computer.
Experiments
- 001 Quantum coin flip
One qubit, a Hadamard gate and a measurement. Run 1, 10, 100 or 1000 shots and watch the histogram settle. - 002 Entanglement
Build a Bell pair with H and CNOT and see correlated 00 and 11 results, then compare with two independent coins. - 003 Build your own circuit
A 3 qubit grid with H, X, Z and CNOT. See probabilities and counts, and share your circuit as a link.
What is a quantum circuit simulator?
A quantum circuit is a list of gates applied to qubits, followed by a measurement. For a handful of qubits an ordinary computer can calculate the exact result. That is what this lab does. It is how most people learn quantum programming, and the same circuits can later be run on real hardware. For the ideas behind it read the quantum computing explainer and how a quantum computer works.
What the simulator cannot do
- It cannot show a quantum speedup. Simulating n qubits costs about 2 to the power n steps, which is why it stops at a few qubits.
- It has no noise. A real machine's results are noisier than these.
- It uses pseudo random numbers, not quantum randomness.
How it works: the simulator keeps the exact quantum state of the qubits as a list of numbers, applies each gate to it, then draws random samples from the resulting probabilities. The random numbers are ordinary pseudo random numbers from your browser, and a real device would add noise. No QNT, wallet or account is needed.
This is an educational simulator, not financial advice. QUANTUM (QNT) is an independent community token on Solana and does not perform quantum computation.
