Researchers from Arizona State factored a 5-bit elliptic curve key with IBM’s 133-qubit #quantum computer in 54 seconds (first time I've heard about a successful factoring attempt vs ECC as opposed to RSA).
Small number of qubits, but a deep circuit. This appears to be a different approach in mathematics and implementation, rather than an improvement on previous best efforts.
"Despite the extreme complexity of the quantum circuit (over 67,000 layers deep), the system maintained sufficient quantum coherence to produce valid interference patterns ... The experiment validates that Shor’s algorithm remains effective even with very deep quantum circuits, suggesting potential scalability for attacking larger cryptographic keys.”

An increasingly interesting area I'm working on (unrelated to post-quantum crypto or quantum computing) is #quantum clocks (picosecond resolution) and sensors. APNT (alternative positioning, navigation, and timing) as a backup option (or eventually a replacement) to GPS is important for a couple of reasons:
* GPS alone is surprisingly easy to jam (either intentionally or accidentally); I learned recently you can spend a relatively small amount of money on Amazon and buy a GPS jammer that runs out of your car's power socket. If you were to forget to unplug that and drive up next to a datacenter or fulfillment center, chaos could ensue.
* NTP is insufficiently accurate for many modern use cases (as one client told me, “What can you do securely in one second? You're limited by what you can *record* in one second.”) Even nanosecond-level resolution is not enough for certain high-speed transactions, and for extremely high frequency or small-size RF applications (think 6G telco rollouts), picosecond-level resolution is needed.
The technology and engineering in this area is further along in terms of commercial applications than quantum computers; this piece covers one such trial (measuring variations in Earth's magnetic field as a backup navigation source to GPS for aviation and maritime applications): https://www.wsj.com/articles/the-secret-to-better-airplane-navigation-could-be-inside-the-earths-crust-6f2c34f4

Of course, besides the critique, they also provide guidance on how a "real" #quantum factorization experiment should be designed.
The text is easy to read even without #QuantumComputing background.
And it is absolutely worthwhile to at least read the footnotes. Some of them definitely made my day!
