Exponential algorithmic speedup by quantum walk

Andrew M. Childs, Richard Cleve, Enrico Deotto +3

We construct an oracular (i.e., black box) problem that can be solved exponentially faster on a quantum computer than on a classical computer. The quantum algorithm is based on a c…

Hilbert Space Structure in Classical Mechanics: (II)

E. Deotto, E. Gozzi, D. Mauro

In this paper we analyze two different functional formulations of classical mechanics. In the first one the Jacobi fields are represented by bosonic variables and belong to the vec…

Hilbert Space Structure in Classical Mechanics: (I)

E. Deotto, E. Gozzi, D. Mauro

In this paper we study the Hilbert space structure underlying the Koopman-von Neumann (KvN) operatorial formulation of classical mechanics. KvN limited themselves to study the Hilb…

Quantum search by measurement

Andrew M. Childs, Enrico Deotto, Edward Farhi +3

We propose a quantum algorithm for solving combinatorial search problems that uses only a sequence of measurements. The algorithm is similar in spirit to quantum computation by adi…

Classical Mechanics and kappa-symmetry

E. Deotto

In this paper we analyze two local extensions of a model introduced some time ago to obtain a path integral formalism for Classical Mechanics. In particular, we show that these ext…
