We sat down with Mark Saffman, chief scientist at @infleqtion, to discuss why neutral atoms have emerged as one of the leading architectures for building scalable quantum computers.
Saffman explains the physics of Rydberg atoms, optical tweezers, and quantum gates, and how these technologies have evolved from laboratory demonstrations into systems capable of scaling toward fault-tolerant quantum computing.

Scarface (2007–2021): The legendary lion who ruled Kenya's Maasai Mara for over a decade
Known for his distinctive facial scar, Scarface survived years of fierce territorial battles and lived to around 14 years old, an exceptional age for a wild male lion
Mexico v England really was the gift that kept giving.
The moment here when Mexico head coach Javier Aguirre had some fun with Anthony Gordon 😂
Aguirre: “Gordon, fuck you” 🤣
Easiest ways to get rich:
1. Sell men lust
2. Sell women beauty
3. Sell parents peace
4. Sell kids dreams
5. Sell the rich safety
6. Sell the broke hope
Same game. Different packaging.
There's nothing "natural" about letting helpless animals die for no reason. You are part of nature. If you want to save them, then nature wants them saved.
