Quantum Computing Guide

A skill for conducting quantum computing research using Qiskit (IBM) and Cirq (Google) frameworks. Covers quantum circuit construction, fundamental algorithms, noise simulation, and practical considerations for running experiments on quantum hardware.

Quantum Computing Fundamentals

Key Concepts

Qubit: The basic unit of quantum information
  - Superposition: A qubit can be in a state |0>, |1>, or any
    linear combination alpha|0> + beta|1> where |alpha|^2 + |beta|^2 = 1
  - Measurement: Collapses to |0> with probability |alpha|^2
    or |1> with probability |beta|^2

Entanglement: Two qubits can be correlated in ways impossible classically
  - Bell state: (|00> + |11>) / sqrt(2)
  - Measuring one qubit instantly determines the other
