THE END OFCRYPTO

When quantum computers reach critical mass, these cryptographic systems will fall in sequence

Get monthly updates on quantum computing progress and what it means for cryptographic security.

The Quantum Doomsday Clock tracks the exponential growth of quantum computer capabilities and predicts when they'll reach the threshold needed to run Shor's algorithm at scale.

We analyze data from every major quantum computer manufacturer including IBM, Google, IonQ, Rigetti, and more. Using exponential regression on physical qubit counts over time, we project when quantum computers will have enough qubits to break current cryptography.

The calculation accounts for the massive overhead of quantum error correction. To get one reliable "logical" qubit, you need hundreds of noisy "physical" qubits working together using surface codes.
