#programming language

State preparation (can't do that in QASM)

The ability to control non-unitary gates (can't do that in Cirq)

Have good structs (I'm looking at you Q#)

Can get the inverse of an arbitrary gate like a state prep (also can't do that in Cirq)

Can simulate a circuit and use GPU parallelism to speed up the process without having to download a WHOLE ANOTHER LIBRARY JUST FOR THE FUCKING GPU PARALLELISM NOT TO WORK (can't do that in Qiskit)

Y'all don't understand the significance of this image to me, but just know, I am so incredibly proud and excited.

I've been developing my own programming language, Quartz, on and off—it's been way more off than on—since May/June of 2025 as a fun project. But when I started, I did not realize how much it would require from me, and keep in mind that I only had a few months of "actual" programming under my belt at the time. However, progress has been made, slowly but surely!

One book kept getting recommended to me twenty times over to help me out: Crafting Interpreters. It was a lot for me at the time, especially since the author used Java and C, neither of which I knew. So, I didn't end up using it; this project has been more of a "learn as you go" kinda thing, which has been good for understanding every little detail and how they connect.

The image I shared shows each step of the process, from lexing to parsing to transpiling to interpreting.

A whole range of expressions should work, including expressions you can't normally find in Python: pipelines, indicated by the arrows (->).

This is my 1983 Nevada Cobol for Commodore 64 CP/M. It requires the CP/M for Commodore 64 Z80 cartridge featured in a previous post.

Nevada Cobol will also run on the Commodore 128, which has 3 internal CPUs: a Z80 CPU for running CP/M, a Commodore 128 BASIC CPU, and a Commodore 64 BASIC CPU.
