WHY INCLUDED

Builds quantum hardware around cat qubits, connecting experimental suppression of selected errors in an oscillator with Alice & Bob’s effort to develop fault-tolerant superconducting computers.

arXiv / Nature PhysicsAlice & Bob

Peronnin’s contribution begins with a concrete physical result: a coauthored experiment showed that an oscillator encoding could suppress bit flips exponentially as its encoded states were separated. That bias changes how error correction can be designed, although the remaining errors still require protection. Co-founding Alice & Bob with Raphaël Lescanne brought this approach into a company focused on quantum computing. His inclusion recognizes the connection between experimental research and sustained system development, without treating a proposed scalable architecture as already complete.

Keep in perspective

Cat-qubit protection suppresses selected errors; it does not remove the need for quantum error correction.
