Long-lived qubits are game-changers for quantum computing. I interviewed Alice & Bob CEO Théau Peronnin last year in a TechFirst podcast, and now they have some exciting news.
Check it out in my latest post at Forbes.
Here’s a high-level summary (thank you ChatGPT!):
- Researchers at a company called Alice & Bob (a quantum computing firm) have achieved a major advance: they created qubits whose coherence (i.e., how long they can maintain quantum states) lasts up to an hour.
- This is hundreds to millions of times longer than the coherence times of typical qubits used today.
- Because qubits today tend to lose their quantum information quickly (due to noise, interactions with the environment, etc.), this kind of extension in coherence is a big deal — it opens up possibilities for more complex quantum operations, fewer error corrections, and more practical implementation of quantum algorithms.
- The article says that achieving qubits that live for an hour could allow much smaller quantum computers to accomplish tasks that today would require huge qubit counts (since fewer errors and less overhead would be needed).
- In effect, this could dramatically reduce the barrier to scalable, fault-tolerant quantum computing.
