Quantum systems undergo unitary transformations from "summary" of The Principles of Quantum Mechanics by P. A. M. Dirac

The transformation of a quantum system is a fundamental concept in quantum mechanics. When a quantum system undergoes a transformation, its state changes according to the laws of quantum mechanics. These transformations are represented by unitary operators, which preserve the inner product of the state vectors in the Hilbert space. Unitary transformations are reversible, meaning that if a quantum system undergoes a unitary transformation, it can always be brought back to its original state by applying the inverse transformation. This property is crucial in quantum mechanics, as it ensures that information about the initial state of the system is not lost during the transformation process. Moreover, unitary transformations play a significant role in quantum dynamics. When a quantum system evolves in time, its state changes according to a unitary transformation generated by the Hamiltonian operator. This evolution preserves the probabilities of different outcomes of measurements, ensuring that the laws of quantum mechanics are respected. In practical terms, unitary transformations are implemented using quantum gates in quantum computing. These gates manipulate the quantum state of a system by applying unitary operations, allowing for complex calculations to be performed efficiently. The reversibility of unitary transformations is essential in quantum algorithms, as it ensures that the computation can be undone if necessary.
  1. The concept of unitary transformations is a cornerstone of quantum mechanics, governing how quantum systems evolve and interact with each other. By understanding the properties of unitary operators, physicists and engineers can harness the power of quantum mechanics to develop new technologies and solve previously intractable problems.
