    "abstract": "Extending our previous work on time optimal quantum state evolution, we\nformulate a variational principle for the time optimal unitary operation, which\nhas direct relevance to quantum computation. We demonstrate our method with\nthree examples, i.e. the swap of qubits, the quantum Fourier transform and the\nentangler gate, by choosing a two-qubit anisotropic Heisenberg model.",
