Quantica Programming Language

Quantica is a high-performance, compiled programming language designed for the next generation of computing: Quantum-Classical Hybrid workflows. Written in Rust and powered by LLVM, it features native quantum primitives, sparse state simulation, and a syntax built for scientists and engineers.

Why Quantica?

Most quantum languages are just Python libraries. Quantica is a compiled language where quantum gates, measurements, and circuits are first-class citizens.

• Native Quantum Syntax: Allocate registers (quantum q[2]) and apply gates (apply H(q[0])) directly in the language.
• Hybrid Runtime: Mix classical logic (if, while, functions) with quantum state manipulation seamlessly.
• Gate Modifiers: Dynamically apply dagger (inverse) and controlled modifiers to any gate or circuit.
• LLVM Backend: Compiles to highly optimized native machine code via LLVM 18 for maximum performance.
• Package Management: Built-in support for modules and packages via import and from syntax.

📦 Installation

Option 1: Windows Installer (Recommended)

For the easiest setup, download the pre-built installer from our latest release.

1. Go to the Releases Page.
2. Download QuanticaInstaller-v0.1.0-alphatest.exe.
3. Run the installer to set up Quantica and add it to your system PATH automatically.

Option 2: Build from Source

If you are on Linux/macOS or prefer building from source, you will need Rust and LLVM 18 installed.

# 1. Clone the repository
git clone [https://github.com/Quantica-Foundation/quantica-lang.git](https://github.com/Quantica-Foundation/quantica-lang.git)
cd quantica-lang

# 2. Build the compiler (release mode recommended for performance)
cargo build --release

# 3. The executable will be at ./target/release/quantica
Add this folder to your PATH or copy the binary to /usr/local/bin

Known Limitations

• Match expressions incomplete (use if/elif/else)
• Try/finally not implemented (try/catch works)
• JIT mode experimental (use interpreter or AOT)
