Quick Summary:
- Alice & Bob, a quantum computing company, has improved the reliability of its “cat qubits,” enhancing quantum computing accuracy.
- Fault tolerance is vital in quantum computing due to challenges like qubit noise and decoherence.
- Traditional error correction focused on reducing bit-flips but often increased phase-flips, posing further issues.
- Cat qubits mimic Schrödinger’s superposition principle, reducing bit-flip errors and minimizing resource needs for error correction.
- Alice & Bob previously achieved a bit-flip lifetime of 138 milliseconds for cat qubits but now report a new method enabling lifetimes of 22 seconds-a 160-fold betterment.Phase-flip rates remained relatively unaffected.
- The improvement was achieved by compressing the quantum states (“squeezing”) to decrease overlap between states, thus lowering bit-flip rates without modifying circuit design significantly.
- This advancement could pave the way for resource-efficient worldwide fault-tolerant quantum computing with applications in chemistry and materials science.
