Time Optimal Unitary Operations
Alberto Carlini, Akio Hosoya, Tatsuhiko Koike, Yosuke Okudaira
abstract: Extending our previous work on time optimal quantum state evolution, we
formulate a variational principle for the time optimal unitary operation, which
has direct relevance to quantum computation. We demonstrate our method with
three examples, i.e. the swap of qubits, the quantum Fourier transform and the
entangler gate, by choosing a two-qubit anisotropic Heisenberg model.
