Cat Qubit

In Plain English

A cat qubit stores information using two opposite oscillation patterns inside a microwave resonator, like a pendulum swinging left versus right. The beauty is that bit-flip errors are exponentially suppressed as the oscillation energy increases, meaning you only need to correct one type of error instead of two. The French startup Alice & Bob is leading commercial development of cat qubits.

Why It Matters for Your Career

Cat qubits represent a promising alternative approach to quantum error correction that could reduce hardware overhead. Alice & Bob and academic labs in Paris and Yale are actively hiring researchers and engineers for cat qubit development. Expertise in superconducting cavities, microwave engineering, and bosonic codes is required for these roles.
