001 Quantum Coin Flip Simulator
SIMULATOR Runs on your device. Not a real quantum computer.
The circuit
One qubit starts at 0. A Hadamard gate (H) turns it into an equal superposition of 0 and 1. A measurement then reads it as an ordinary bit. The circuit is: q0: H, measure.
Run it
What you are seeing
After H the state is an equal mix of 0 and 1, so each outcome has probability one half (the bars show the exact 50% before you take any shots). Each shot gives one random result. With 1 shot you get a single 0 or 1. With 10 shots the split is usually uneven. With 1000 shots it sits close to half and half. Probabilities are only visible in the long run, which is true on real hardware too, where programs are repeated many times (shots). The chance of an outcome is the square of its amplitude, called the Born rule.
A fair classical coin gives the same histogram, so this single experiment does not show anything a classical computer cannot. It becomes interesting when qubits interfere or become entangled, as in experiment 002 and experiment 003. Learn more in what is a qubit and superposition explained.
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.
