Quantum computing company Alice & Bob has improved the reliability of its cat qubits, which could make tomorrow's quantum computers far more accurate.
Fault tolerance is a major challenge in quantum computing. This is because the qubits in quantum computers are "noisy" and susceptible to decoherence — the loss of quantum information due to interference from the external environment. Improving qubits' reliability by implementing fault-tolerant technologies has therefore been a key research area.
