Quantum interconnect Updated 2025-07-16
"Quantum interconnect" refers to methods for linking up smaller quantum processors into a larger system.
As of 2024, seemingly few organizations developing quantum hardware had actually integrated multiple chips in interconnects as part of their main current roadmap. But many acknowledged that this would be an essential step towards scalable compuation.
The name "quantum interconnect" is likely partly a throwback to classical computer's "chip interconnect".
Sample usages of the term:

Researchers have demonstrated directional photon emission, the first step toward extensible quantum interconnects

XML file format (but with 99% of the action of interest in a domain-specific language on the
CsInstruments
and CsScore
elements) that can be played and the reference implementation. Offers complex effects out-of-box apparently.Allows you to easily define instruments with seemingly arbitrary mathematical functions, and then use them to play notes at given time intervals.
The instrument functions can be parametrized, and each note played can have different parameters.
The instrument definition actually defines a block diagram graph, much like a hardware synthesizer would.
Csound is so not-bloated that it contains an UI system. And it includes an interactive virtual MIDI keyboard that interacts with parameter knobs: www.csounds.com/manual/html/MidiTop.html
But hey, it's fun. And like any other good domain-specific language, debugging it is barbaric of course.
If only it had been written in Python... the array manipulation boilerplate would be likely perfect for NumPy, and this would have been exactly what Ciro Santilli wanted!
CSound states that one of its design goals is backward compatibility, and it shows. Some of the stuff is utterly arcane, e.g. you have to remember what
GEN10
, GEN11
, etc. mean instead of having named enums.It just worked on Ubuntu 20.04 no questions asked:which runs this file: github.com/csound/csound/blob/92409ecce053d707360a5794f5f4f6bf5ebf5d24/examples/xanadu.csd and this plays a relly cool sound demo:
sudo apt install csound
git clone https://github.com/csound/csound
cd csound
git checkout 92409ecce053d707360a5794f5f4f6bf5ebf5d24

TODO find the most amazing set of songs made with it on GitHub? Some examples:
- www.csounds.com/toots/index.html has a good 101 on instrument design
- Csound FLOSS manual
- iainmccurdy.org/csound.html about 100 CC BY-SA examples. Each is a minimal study showing a specific technique, not a full composition, some seem advanced. Dude's a beast.
- github.com/csound/csound/tree/f2e70825fb543a6b15011c6984371f61ab2a00dd/tests/soak in-tree minimal examples
- github.com/csound/manual/tree/4049b286493d972ff7248b5596e47e7ae97a0cf9/examples contains the examples for the manual which is rendered at: It's insane, but it's fun! Ah those newbs who separate manuals from main tree.

Documentation-wise, it's a bit lacking. The only dude who can explain it really well, Dr Richard Boulanger, made the "The Csound Book" closed source, so, congrats, this will forever hurt the popularity of Csound.
