The Quantum Advantage: Schrödinger's Cat and Faster Guessing

Physicists at EPFL have proposed a "critical Schrödinger cat code" for advanced resilience to errors in quantum computing. The encoding scheme is based on Schrödinger's cat thought experiment, where the 0 and 1 states of a qubit are encoded onto two opposite phases of an oscillating electromagnetic field in a resonant cavity. The "critical" part of the code refers to operating close to the critical point of a phase transition, which enhances error suppression capabilities and resistance to random frequency shifts. This breakthrough paves the way for building better quantum computers.
