# Introducing Qx: A Pure Elixir Quantum Computing Simulator

We're excited to introduce Qx, a quantum computing simulator built entirely in Elixir. Qx makes quantum computing accessible to developers, researchers, and students who want to explore quantum algorithms without needing specialized hardware.

# Why Qx?

Quantum computing represents the next frontier in computation, but access to real quantum computers remains limited. Qx bridges this gap by providing:

Pure Elixir Implementation: No external dependencies on quantum libraries
Educational Focus: Clear, readable code that helps you understand quantum mechanics
Interactive Notebooks: Built-in support for Livebook for hands-on learning
Production Ready: Fast performance for simulating small to medium quantum circuits

# Key Features

# 1. Quantum State Manipulation

Qx provides intuitive APIs for creating and manipulating quantum states:

elixir

# Create a superposition state
state = Qx.Qubit.new(0)
  |> Qx.Gates.hadamard()

# Measure the state
{result, _new_state} = Qx.Simulation.measure(state)

# 2. Quantum Gates Library

Access a comprehensive library of quantum gates:

Single-qubit gates: Pauli X, Y, Z, Hadamard, Phase, T
Multi-qubit gates: CNOT, Toffoli, SWAP
Custom gate creation: Define your own unitary transformations

# 3. Circuit Building

Build complex quantum circuits with an elegant API:

elixir

circuit = Qx.QuantumCircuit.new(3)
  |> Qx.QuantumCircuit.add_gate(:hadamard, [0])
  |> Qx.QuantumCircuit.add_gate(:cnot, [0, 1])
  |> Qx.QuantumCircuit.add_gate(:ccnot, [0, 1, 2])

# Real-World Applications

Qx is perfect for:

Education: Teaching quantum computing concepts in universities
Algorithm Development: Prototyping quantum algorithms before running on real hardware
Research: Exploring quantum phenomena and testing hypotheses
Hobby Projects: Learning quantum computing at your own pace

# Getting Started

Installation is simple with Mix:

elixir

def deps do
  [
    {:qx, "~> 0.2.0"}
  ]
end

Then explore our interactive guides available on this site, or dive into the comprehensive API documentation.

# What's Next?

We're actively developing Qx with exciting features on the roadmap:

Quantum error correction simulation
Noise modeling for realistic quantum systems
Integration with real quantum hardware backends
Performance optimizations for larger circuits
More algorithm implementations (Shor's, Grover's, VQE)

# Community

Qx is open source and we welcome contributions! Whether you're fixing bugs, adding features, or improving documentation, we'd love your help.
