Josephson equations Updated 2025-07-16
Two equations derived from first principles by Brian Josephson that characterize the device, somewhat like an I-V curve:where:
- : Josephson current
- : the Josephson phase, a function defined by the second equation plus initial conditions
- : input voltage of the system
- : current across the junction, determined by the input voltage
Note how these equations are not a typical I-V curve, as they are not an instantaneous dependency between voltage and current: the history of the voltage matters! Or in other words, the system has an internal state, represented by the Josephson phase at a given point in time.
To understand them better, it is important to look at some important cases separately:
- AC Josephson effect: V is a fixed DC voltage

Quantum computer physical implementation Updated 2025-07-16
Lists of the most promising implementations:
As of 2020, the hottest by far are:
Super quick overview of the main types of quantum computer physical implementations, so doesn't any much to a quick Google.
He says he's going to make a series about it, so then something useful might actually come out. The first one was: Video "How to Turn Superconductors Into A Quantum Computer by Lukas's Lab (2023)", but it is still too basic.

Josephson voltage standard Updated 2025-07-16
The most practical/precise volt standard.
It motivated the definition of the ampere in the 2019 redefinition of the SI base units
The wiki page en.wikipedia.org/wiki/Josephson_voltage_standard contains amazing schematics of the device, apparently made by the US Government.
- youtu.be/VoRab8U2eS0?t=354 the desired output voltage is 10V
- youtu.be/VoRab8U2eS0?t=475 lists the three most commonly used 10V implementations currently:
- youtu.be/6pgGNJby1lw?t=296 gives the experimental setup used to compare two different references. Notably it involves a nanovoltmeter
Journey to the West Updated 2025-07-16
This is just the most charming of the Four Great Classic Novels.
The definitive television series adaptation is obviously Journey to the West. It just manages to capture all the charms of Sun Wukong and Zhu Bajie.

You just couldn't resist Googling it and clicking this page, could you? You naughty, naughty bearded programmer nerd. Yes, I'm talking to you.
TODO it is quite hard to actually find non-automatically generated ASCII art of people fucking, most of them are just sexy/horny women drawn by bearded nerds, likely and based on sticky physical paper porn magazines from the 80's, good old days.
