This talk shows how to recast quantum algorithms in a purely Hamiltonian form, substituting time-dependent Hamiltonian controls for the conventional quantum logic gate picture. Using the example of the quantum singular value transformation (“the mother of all quantum algorithms,” according to Ike Chuang), I show that Hamiltonian quantum computing can supply significant advantages in terms of time and decoherence compared with the gate based model.
