QuantumLogics is a software house dedicated to crafting high-quality software solutions while actively contributing to the open-source community. We believe great software is built at the intersection of precision, performance, and creativity — and we put that philosophy into everything we ship.

From building production-grade commercial applications to designing programming languages from the ground up, our team works on projects that push what's possible.

A multi-paradigm scripting language with a bytecode compiler and VM — written in C++17

Quantum is a dynamically-typed, cybersecurity-ready scripting language that compiles .sa source files to bytecode and runs them on a custom register-stack virtual machine. What makes it unique is its multi-syntax design — Python-style, JavaScript-style, and C/C++-style syntax are all valid in the same file.

Highlights:

• 🔀 Multi-syntax — write code the way you think, mix styles freely
• 🔒 Cybersecurity-ready — built-in SHA256/SHA1/MD5, AES-128, HMAC, base64, XOR, entropy analysis, and network helpers
• ⚡ Bytecode VM — compiles to a compact bytecode format and runs on a custom stack-based VM
• 📦 Self-contained executables — quantum file.sa produces a standalone .exe with no runtime dependencies
• 🔁 REPL — interactive mode via qrun with persistent VM state across lines
• 🧪 Batch test runner — crash-guarded test suite with --test flag

Run your first Quantum program:

quantum hello.sa     # compiles → hello.exe, then launches it
qrun    hello.sa     # interprets directly, nothing written to disk
qrun                 # starts interactive REPL

Example — multi-syntax in one file:

# Python-style
def greet(name): return "Hello, " + name

# JavaScript-style
function square(n) { return n * n }

# Arrow
double = (x) => x * 2

print(greet("World"), square(5), double(7))

First-class editor support for the Quantum language

The official Visual Studio Code extension for Quantum brings a polished development experience to .sa files, including syntax highlighting, code snippets, and language-aware tooling — available as a submodule alongside the main language repository.

A clean, fast Quran web app

A lightweight web application where users can search, read, and explore Quranic verses in Arabic with English translations. The project also provides a complete JSON dataset for developers building Quran-related tools or offline applications.

A living collection of edge cases that make Quantum stronger

A curated repository of failed test cases that expose edge cases, break assumptions, and drive the Quantum language toward more resilient and battle-tested code. Contributions that break things are welcomed.

At QuantumLogics, our work spans:

• Custom programming languages & compilers — from lexer to bytecode VM
• Developer tooling — IDE extensions, CLI tools, and language servers
• Web applications — fast, accessible, and well-crafted
• Cybersecurity tooling — built into our language's standard library by default
• Commercial software — bespoke solutions for clients across industries

We welcome contributions across all our open-source repositories. Whether you're fixing a bug, adding a language feature, writing tests, or improving documentation — every bit counts.
