Quantum Canonical Transformations and Integrability: Beyond Unitary Transformations
Quantum canonical transformations are defined in analogy to classical canonical transformations as changes of the phase space variables which preserve the Dirac bracket structure. In themselves, they are neither unitary nor non-unitary. A definition of quantum integrability in terms of canonical transformations is proposed which includes systems which have fewer commuting integrals of motion th...
متن کاملQuantum Canonical Transformations revisited
A preferred form for the path integral discretization is suggested that allows the implementation of canonical transformations in quantum theory. 1 Canonical Transformations in Quantum Theory Canonical transformations are of great utility in classical theory [Goldstein, 1980]; however they do not work so well in quantum theory, giving rise to anomalous (order h̄) potential like terms [Gervais an...
متن کاملCanonical Transformations in Quantum Mechanics
Quantum canonical transformations are defined algebraically outside of a Hilbert space context. This generalizes the quantum canonical transformations of Weyl and Dirac to include non-unitary transformations. The importance of non-unitary transformations for constructing solutions of the Schrödinger equation is discussed. Three elementary canonical transformations are shown both to have quantum...
متن کاملDiscrimination of Unitary Transformations and Quantum Algorithms
Quantum algorithms are typically understood in terms of the evolution of a multiqubit quantum system under a prescribed sequence of unitary transformations. The input to the algorithm prescribes some of the unitary transformations in the sequence with others remaining fixed. For oracle query algorithms, the input determines the oracle unitary transformation. Such algorithms can be regarded as d...
