From niobium/sapphire to tantalum — history of longer coherence

1:23:24>> Yeah. challenge. It's it's it's multiple groups in the university. The chemistry department was involved. The electrical engineering department was involved. Like like there's all these different players that were like, "Oh, actually I'm really good at tentelum." >> Yeah. Right. >> And I'm pretty sure you need tentelum, right? And then somebody else was like, "Put this on the silicon and you're going to need a higher vacuum. >> You're going to need a higher vacuum." Yeah. Someone was like, "You're going to need more cowbell." >> Yeah. Yeah. Yeah. And there's all of these different different factors that are coming in in this ecosystem at Princeton to create this cubit. And this cubit is amazing. It's got >> the best one. >> The best one had 1.7 milliseconds. >> That's crazy. >> And to tell you just how how big this

1:24:05is, you know, before you were getting to.3. >> Yes. >> The best one is now five times. >> Right. Right. >> And that.3 was in a lab setting. It's not at the industrial setting. Okay. M so you're getting you're getting almost 20 times to 25 times the industrial setting of stuff right and you you might be thinking you know a millisecond that's a thousandth of a second thousandth of a second is not very long well the gates right the the the stuff that we're using for quantum stuff is on the order of tens of nanconds >> right so you can fit in a lot more stuff >> in one millisecond now a nancond is >> um a 100 thousandth of a millisecond.
