I have not seen any progress or breakthroughs in the QC field at all that are significant.

If the only goal for QC is to try to run Shor's algorithm or to "try to break the bitcoin blockchain" then it is worse than useless.

- Intel can now do 2D which means a Surface code can be run on these devices: https://arxiv.org/abs/2412.14918

- HRL can now do 2D as well: https://arxiv.org/abs/2502.08861

- They are solving the wiring problem: https://www.nature.com/articles/s41565-023-01491-3

- Their interconnects are high fidelity: https://www.nature.com/articles/s41586-025-09827-w
