Yeah, sure. If you can follow everything in this article you’re a better thinker than I am. Nonetheless, I found it a “fun” read (yeah, I have an interesting definition of “fun”). Nonetheless, check out https://nation.lk/online/10-easy-steps-to-half-understanding-time-crystals-173866.html and see if you think it’s a fun read.
In essence a team of scientists have made great strides in helping two distant quantum computers to become entangled, which is one of the steps necessary to reach a quantum internet.

I found this to be a good article discussing and to some extent explaining quantum entanglement. Not only the broad brush explanation that I usually see but some of the more subtle elements like a particle is likely partially entangled with more than one other particle so knowing the state of one may not completely convey the state of the other. https://interestingengineering.com/quantum-entanglement is the article I reference.
About half way thru the article explains superposition and entanglement using an analogy of spinning coins. It’s an interesting analogy and one that could help folks who don’t understand those concepts. Aside from that, the article is interesting because it discusses hacking bitcoin (or, more generally, a blockchain) and why more qubits are needed as a sort of error correction..
Using a silicon carbide platform. 5 seconds is long enough to send a signal via light to the moon and back or around the earth 40 times. A lot can happen over the Internet in 5 seconds. Perhaps a quantum internet is not so far away? See https://eandt.theiet.org/content/articles/2022/02/five-second-record-set-for-preservation-of-quantum-states/ for details
QuEra Computing (https://www.quera.com/) has just launched with a 256-qubit computer. They call it a simulator, I guess because it uses a different underlying technology but it supposedly really is a 256 qubit quantum computer! See https://venturebeat.com/2021/11/17/quera-offers-new-quantum-advantage-based-on-harvard-and-mit-research and. yes, this has significant implications on security which impacts on blockchain, wifi security, network security, ssh, and pretty much everything else that relies on encryption. https://www.fastcompany.com/90698019/quera-quantum-computing-startup is another good and short article.
This is really pretty new (just announced today) and there aren’t a lot of analyses out there yet so I’d encourage you to do your own searches to keep up with it.
Maybe it is today but tomorrow? This should come as no surprise but quantum computing could change everything. https://www.technologyreview.com/2021/11/03/1039171/hackers-quantum-computers-us-homeland-security-cryptography
