qlibx 1.0.0

A lightweight quantum computing library for foundational tools and mathematical operations.

Qlibx: A Quantum Computing Library

Qlibx is a Python library designed to provide foundational tools for quantum computing. It offers classes and methods to represent and manipulate quantum states, operators, and their interactions. The library is lightweight and focuses on the mathematical foundations of quantum mechanics, making it an excellent choice for learning and experimentation.

Features

• Quantum States:

  • Ket and Bra classes to represent quantum states.
  • Support for operations like addition, subtraction, scalar multiplication, tensor products, and inner/outer products.

• Quantum Operators:

  • Operator class to represent quantum operators.
  • Methods for Hermitian, unitary, and normality checks.
  • Commutator and anti-commutator calculations.
  • Spectral decomposition and partial trace.
  • Von Neumann entropy calculation.

• Predefined Operators:

  • Pauli matrices (pauli_x, pauli_y, pauli_z) and the identity matrix.

Installation

Clone the repository and include the library in your Python project:

git clone https://github.com/your-repo/qpylib.git
cd qpylib

Ensure the qpylib directory is in your Python path.

Usage

Importing the Library

from qpylib import Ket, Bra, Operator

Creating Quantum States

# Create a Ket vector
ket = Ket([1, 0])

# Create a Bra vector
bra = Bra([1, 0])

Quantum Operations

# Inner product
inner = ket.inner_product(bra)

# Outer product
outer = ket.outer_product(bra)

# Tensor product
tensor = ket.tensor(Ket([0, 1]))

Working with Operators

# Define an operator
op = Operator([[0, 1], [1, 0]])

# Apply operator to a Ket
result = op.op(ket)

# Check if the operator is unitary
is_unitary = op.unitary()

---

Example: Quantum Circuit Simulation

from qpylib import Ket, Operator

# Define a quantum state |ψ⟩
psi = Ket([1, 0])

# Define a Pauli-X gate
pauli_x = Operator(Operator.pauli_x)

# Apply the gate
new_state = pauli_x.op(psi)

print(new_state)
