LaserPy-Quantum 0.0.7

Laser physics / simulation utilities

LaserPy_Quantum

LaserPy_Quantum provides an intuitive interface for simulating complex laser interactions, current drivers, and interferometer setups, with plans to offload performance-critical components to Rust for high-speed numerical computations. A high-level, open-source Python library designed for the theoretical simulation of laser systems in quantum communication and cryptographic protocols.

🚀 Features

• High-Level API for constructing laser-based quantum system simulations.
• Support for arbitrary waveform generation (AWG) and current drivers.
• Simulation of master–slave laser - configurations with injection locking.
• Built-in support for asymmetric Mach–Zehnder interferometers (AMZI) and photon detectors.
• Clock-driven simulation engine for precise time-step control.
• Extensible architecture for future modules and Rust acceleration.

📦 Installation

• LaserPy_Quantum is now on PyPI.

pip install LaserPy-Quantum

• Also, LaserPy_Quantum is under active development and welcomes opensource developers. Clone the repository locally:

git clone https://github.com/Mathwizard1/LaserPy_Quantum.git
cd LaserPy_Quantum
pip install -e .

Ensure you’re using Python 3.9+.

📝 Example Usage

Below is an example of using LaserPy_Quantum component and connection system with simulator:

from LaserPy_Quantum import Clock, PhysicalComponent
from LaserPy_Quantum import Connection, Simulator

from LaserPy_Quantum import display_class_instances_data

simulator_clock = Clock(dt=0.01)
simulator_clock.set(2)

simulator = Simulator(simulator_clock)

physical_device1 = PhysicalComponent()
physical_device2 = PhysicalComponent()

simulator.set((
    Connection(simulator_clock, physical_device1),
    Connection(physical_device1, physical_device2)
))

simulator.reset(True)
simulator.simulate()
time_data = simulator.get_data()

physical_device1.display_data(time_data)
physical_device2.display_data(time_data)

display_class_instances_data((physical_device1, physical_device2), time_data)

🧠 Use Case: Laser simulations

LaserPy_Quantum’s current use case is simulating quantum key distribution (QKD) protocols using master–slave lasers with injection locking and interferometer-based detection.
It allows researchers and engineers to prototype and test theoretical setups before implementing them in hardware.

🔧 Planned Features

• Rust-based backend for high-performance simulation.
• Expanded library of optical components (modulators, detectors, etc.).
