Quantum Error Correction Calculator
The Quantum Error Correction Calculator simulates the famous 3-qubit bit-flip code — the first quantum error-correcting code (Shor, 1995). Watch how quantum redundancy detects and corrects a single qubit flip.
About the Quantum Error Correction Calculator
The Quantum Error Correction Calculator is a real quantum computing simulator that demonstrates the groundbreaking 3-qubit bit-flip quantum error correction code — the first QEC code ever discovered by Peter Shor in 1995. This Quantum Error Correction Calculator shows exactly how quantum redundancy and syndrome measurement can detect and correct errors, making large-scale quantum computers possible.

How the 3-Qubit Bit-Flip Code Works
Why This Calculator Is Revolutionary
Quantum error correction is the #1 challenge in building useful quantum computers. This calculator shows: • How quantum states survive noise • The power of entanglement in error detection • Why we need redundancy in quantum systems • The foundation of all modern QEC codes (Steane, surface codes, etc.) Used by IBM, Google, and all quantum computing researchers.
