#439 minutes? Hmm, still not good enough for long-term backup of your qubits :)

#5This is really exciting! For those not familiar, 180s (edit: as previously published[2]) is a phenomenal amount of time at room temperature and it seems they've beaten that now too. I was just looking for this recently in another comment thread[1] too when talking about the really cool things you can do when you have access to ultra-pure silicon-28 (which has been made as a result of something that sounds quite boring–making a more accurate standard for the kg–and is now having some exciting side benefits). Direct link to paper is here[2]; I think it's open access.
I was lucky enough to see a talk by one of the authors recently and was left very impressed. Quantum computing is probably the 'sexiest' application of ultra-pure silicon-28 but there are so many others besides, including being able to use ultra-fine optical transitions to identify defect complexes within the silicon (arrangements of impurity atoms that can influence the properties of silicon-based devices). If I remember rightly, there were several defects that had been misidentified for years based on entirely reasonable Occam's-razor like reasoning that have now been correctly identified thanks to this work.

You can use Amazon Glacier with the "Almost Absolute Zero" flag for long term storage.

That's 1800s.. a factor of 10 more!

Doesn't the no cloning theorem mean that you cannot back up a qubit regardless of how stable it is?

#10Silicon never ceases to amaze me. While much of the research in solid state physics these days is around novel materials like graphene, silicon continues to dominate solid-state applications including all conventional computer processors and most solar cells and will prove incredibly hard to unseat in these areas. Now it appears to be a leading contender for quantum computing platforms. It's an earth-abundant material with billions of research dollars poured into it to support computing, so seeing progress in silicon quantum computing means real hope for applications.
