Alice & Bob
“Error correction, baked into hardware.”
Paris-based startup building 'cat qubits' that suppress errors in hardware, aiming for a fault-tolerant machine with far fewer qubits.
'Alice and Bob' are the classic characters in every quantum cryptography protocol.
The Story
Founded in Paris to commercialize cat-qubit research from ENS and Yale.
Demonstrates a cat qubit with bit-flip lifetimes measured in seconds.
Raises a €27M round to build the first cat-qubit chip.
Publishes roadmap targeting a 100-logical-qubit machine with only ~1,500 physical qubits.
