The Antikythera Mechanism actually tracks the differing speed of the moon’s elliptical orbit and calculates lunar and solar eclipses to the day and HOUR.
50 is my recollection, though I know the Chinese are working on one that will supposedly go higher.
From what I know, I think they’ve done simulations of 40-50 qubits, and IBM had a 50 qubit computer but it decohered pretty fast. I don’t know if the 50 qubit computer can actually be used by scientists to meaningfully perform calculations or not.
My impression is that for now, 20 qubits is the most they can make that they can actually get to work to do calculations.
But so many groups are working on them, I’d be surprised if we don’t have quantum computers with large numbers of qubits by 2025. Who knows what counts as large numbers. 100? 10 million? No idea.
But its a pretty complex piece of technology.
This show, and the “Hand Banana” episode of Aqua Teen Hunger Force, and Winnebago Man are the only shows I’ll never delete from my DVR.
I’ve often wondered what this says about me…
Tonight…you
I think by those criteria, for 1917, the R-class Zeppelin wins. The largest and most advanced aircraft of the time.
For 1817 I would nominate the Jacquard loom - a punch-card controlled loom that could produce pattered textiles.
You wanna back that up?
