It'll be interesting to see if the cryptocurrency mining industry will help subsidize this work, since their primary edge is power/performance.

During stable price periods, the power/performance of cryptocurrency miners runs right up to the edge of profitability, so someone who can come in at 20% under that would have a SIGNIFICANT advantage.

Huh, this seemed a bit too good to be true on first reading. But given that the limits on computing power tend to thermal, and that a superconducting computer presumably wouldn't produce any heat at all, it does kind of make sense.

The system as a whole will produce heat, but less.

Given the cooling requirements, I suppose it would create completely impassable rift between datacenter computing and other kinds. Imagine how programming and operating systems might look in a world where processing power is 80x cheaper. Considering that "data centers alone consume 2% of world's enegy", I think it's worth it.

>Imagine how programming and operating systems might look in a world where processing power is 80x cheaper.

So like 2009 compared to 2021? Based on that, I'd say even more inefficient webshit.

Anyone remember Java 3D? 'cause I'm imagining Java 3D!

> We use a logic primitive called the adiabatic quantum-flux-parametron (AQFP), which has a switching energy of 1.4 zJ per JJ when driven by a four-phase 5-GHz sinusoidal ac-clockat 4.2 K.

The landauer limit at 4.2K is 4.019×10^-23 J (joules). So this is only a factor of 38x away from the landauer limit.

In this paper, we study the use of superconducting technology to build an accelerator for SHA-256 engines commonly used in Bitcoin mining applications. We show that merely porting existing CMOS-based accelerator to superconducting technology provides 10.6X improvement in energy efficiency. https://arxiv.org/abs/1902.04641

This could explain the extreme push to the Cloud, for example with Atlassian who discontinues its Server products entirely, and only keeps Data Center or Cloud versions. It behaves as if personal computing or server rooms in companies won’t be a thing in 2025.
