🔥 Google’s quantum processor could perform 1,000 times better with Princeton’s new qubit

Princeton researchers built a superconducting qubit with much longer coherence than today’s standard designs, on the order of milliseconds instead of microseconds.

The improvement comes from using tantalum on high purity silicon, which dramatically reduces energy loss. Longer coherence means fewer errors and far more useful computation.

In principle, dropping this qubit into existing quantum processors could yield ~1,000x effective performance gains, with benefits compounding as systems scale. This is
