A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

The optics are just the medium through which the qubits are entangled, the interesting part isn't the lasers but the interaction between physically-separated qubits.

You could theoretically accomplish the same thing by physically bonking the qubits together so that they interact via nuclear forces instead of the electromagnetic field, like they did with entire molecules at Durham University a few weeks back: https://www.msn.com/en-us/news/technology/world-first-quantum-entanglement-of-molecules-at-92-fidelity-uk-achieves-magic/ar-AA1xfHI9
