What I'm holding is going to space!
Infleqtion CTO Pranav Gokhale showed Thinking On Paper a new type of glass cell.
Titanium is welded to glass using an ultrafast laser system. It has to survive the launch pressures of a rocket, then hold a vacuum better than space itself once it's in orbit.
Building something that delicate and that strong at the same time is one of the hardest things to do in quantum hardware manufacturing.
This is what quantum sensors headed to space actually look like.

Will the glass expand as the titanium expands?
So, lasers.
Cool we do laser glass titanium seal welding at Goddard …. 15 yrs ago? As for CTE we match the glass type w the metal. SF11 and Invar or Ti and BK7, etc…. But the operating temp range is limited.
How do you get a better vaccum than a vaccum?
Cool! I thought metal welded itself in space if its bare metal as there is nothing in between the molecules at that time. But I guess as its glass to metal makes sense
The thickness of the glass gives away a lot let's just say it's low coefficient glass if not pure silica. Those parameters which are shown are not used anything besides holding a monitor.
What company’s are involved?
Whats the symbol on the hat for?
I would be at @apple.com this is an idea for their customer and sscience to back. #whereisappleonthis
Welding glass and titanium wow! What kind of glass and is the glass that strong to handle pressures?
He didn't come back to what it meant
These guys have research papers for this?
Why aren’t we using what already got us to the moon?
Nah dog, we did that in the 60s wyfw?
Is there a third filler/consumable material to achieve the weld?
