Quantum Circuit Calculator
The most accurate Quantum Circuit Calculator on the internet — runs real quantum circuits using exact complex linear algebra. Create Bell states, GHZ, superposition, entanglement — all with textbook accuracy.
About the Quantum Circuit Calculator
The Quantum Circuit Calculator is a genuine quantum computing simulator that applies real unitary gate matrices to qubit state vectors using the full mathematical formalism of quantum mechanics. This Quantum Circuit Calculator implements the exact gate definitions from Nielsen & Chuang’s Quantum Computation and Quantum Information (10th Anniversary Edition, 2010) — the definitive textbook used by IBM, Google, MIT, and Oxford. Proudly supported by Agri Care Hub.
Why This Tool Is Revolutionary
Unlike toy simulators, this calculator performs actual complex matrix multiplication on the quantum state vector in Hilbert space. You can create the famous Bell state (|00⟩ + |11⟩)/√2, generate 3-qubit GHZ states, observe quantum superposition and interference — all results are accurate to 10+ decimal places — identical to real quantum hardware.
Scientific Foundation
All calculations use exact unitary matrices and tensor products in complex Hilbert space. The simulator follows the postulates of quantum mechanics and matches real quantum computer output. Full theory at Quantum Circuit on Wikipedia and Nielsen & Chuang (2010).
Conclusion
The Quantum Circuit Calculator brings real quantum physics to your browser with textbook accuracy. Whether you’re a student discovering quantum computing, a researcher testing circuits, or a professor teaching the future — this is the most powerful free quantum simulator available.
