Vectors

Below are the core mathematical ingredients of quantum computation, quantum vectors that define how states are represented and linear transformations that show how those states evolve.

Quantum Vectors:
  • State Representation: A quantum vector |ψ⟩ represents the state of a system in multidimensional space.
  • Superposition: |ψ⟩ = [α β]^T captures all possible superpositions of basis states |0⟩ and |1⟩.
  • Computational Basis: The fundamental states that form the building blocks of quantum computation.
Linear Transformations:
  1. Matrix Operations: Linear transformations represented by matrices act on vectors to produce new states.
  2. Quantum Gates: Unitary operators that preserve probability and phase in quantum systems.
