Optical effect advances quantum computing with atomic qubits to a new dimension
- major4x 3y agoDoes anybody know how the coupling between the individual qubits is achieved/configured?
- staunton 3y agoIt sounds like the article focuses on trapping...
- FinnKuhn 3y agoYou can find the paper here, maybe that helps: https://arxiv.org/abs/1902.05424 https://arxiv.org/abs/1902.05424

- noobermin 3y agoSo this is a potentially useful innovation but this doesn't solve the largest issue with decoherence which is the actual bottleneck.
- glitchc 3y agoOne incremental step at a time. It took ~50 years from their discovery before transistors could be mass produced.
- dekhn 3y ago20 years from the first idea to working example, not 50, and was in scaled production only 10 years later. Perhaps would have been faster if vacuum tubes hadn't been so successful. I think it's time to conclude that quantum computer is just significantly harder than transistors for computing.
- glitchc 3y agoWe have working single qubits today. Just not millions of them. Much of it has to do with investment. Previous govts poured a great deal of money into transistors. It's mainly private funding for quantum. Even private isn't the same scale as Bell Labs, adjusting for inflation.
- willy_k 3y agoWho’s claiming it’s not significantly harder? That is a bad reason to give up, if that’s what you’re advocating for.
- CyberDildonics 3y agoThat is a bad reason to give up, if that’s what you’re advocating for. Where did they say anything like that?
- willy_k 3y agoIf they weren’t implying that, the statement was redundant.
- CyberDildonics 3y agoThat doesn't make sense at all. I think they were just showing that quantum computer advancement isn't going to have the same rapid development that transistor based computers did a few decades ago.

- sp332 3y agoGetting to tens of thousands of qubits is very helpful for quantum error correction schemes. That can help mitigate decoherence.
- packetlost 3y agoI believe the decoherence times for atomic qubits (at least neutral atom) is much higher than that of trapped ions or superconducting, on the order of seconds.
