About Quantum Randomness
In quantum mechanics, measuring a qubit in superposition produces fundamentally unpredictable outcomes. When a Hadamard gate is applied to |0⟩, the qubit enters a 50/50 superposition — and measurement collapses it to |0⟩ or |1⟩ with equal probability.
This tool simulates that process using the Web Crypto API (crypto.getRandomValues), which provides cryptographic-grade entropy from your system's hardware random number generator — the closest approximation to true quantum randomness available in a browser.
The generated numbers are suitable for cryptographic key generation, secure token creation, simulations, and any application requiring high-quality randomness.
