Quantum Computers Cross Critical Error Threshold

“This computational alchemy has its limits. If the physical qubits are too failure-prone, error correction is counterproductive — adding more physical qubits will make the logical qubits worse, not better. But if the error rate goes below a specific threshold, the balance tips: The more physical qubits you add, the more resilient each logical qubit becomes.

Now, in a paper published today in Nature, Newman and his colleagues at Google Quantum AI have finally crossed the threshold. They transformed a group of physical qubits into a single logical qubit, then showed that as they added more physical qubits to the group, the logical qubit’s error rate dropped sharply.” (Quanta Magazine)

The SpinLaunch A-33 Suborbital Mass Accelerator in New Mexico. SpinLaunch is developing a centrifugal mass accelerator, the A-33, to launch small satellites into space without traditional rocket fuel. By spinning payloads to extreme speeds (up to 10,000Gs) inside a giant centrifuge, the system uses kinetic energy to fling satellites to high altitudes, where a small propulsion stage takes over to reach low-Earth orbit. This method promises a significant reduction in both launch costs and fuel consumption compared to conventional rocket launches. (via Gizmodo/SpinLaunch)
