Quantum Simulated Annealing (2007)

Somma, R., Boixo, S., Barnum, H.

We develop a quantum algorithm to solve combinatorial optimization problems through quantum simulation of a classical annealing process. Our algorithm combines techniques from quantum walks, quantum...

Continuous in-situ measurements of gases (H2, H2S, CH4, N2, O2, He and CO2) at the fumarole “Soffionissimo” (Solfatara volcano, Southern Italy). (2007)

Wiersberg, T.; Istituto Nazionale Di Geofisica E Vulcanologia, Sezione Roma1, Roma, Italia, Somma, R., Rocco, A., De Rosa, M., Zimmer, M., Quattrocchi, F., ...

Temperature measurements and gas extraction were done at the fumarole very close to the “Bocca Grande”. The temperature measurements were performed with a temperature probe (K-type thermocouple),...

The carbonate tectonic units of northern Calabria (Italy): a record of Apulian palaeomargin evolution and Miocene convergence, continental crust subduction, and exhumation of HP-LT rocks. (2007)

Iannace, A., Vitale, S., D'Errico, M., Mazzoli, S., Di Staso, A., Macaione, E., ...

In northern Calabria (Italy), the metasedimentary succession of the Lungro?Verbicaro tectonic unit preserves mineral assemblages suggesting underthrusting to depths in excess of 40 km. Internal...

The main lithoid material origin of the Temple of Hercules in San Marco d'Alunzio (Sicily, Italy) (2007)

Sacca', C, Sacca', D, Nucera, P, De Maria, M, De Fazio, A, Somma, R

This study compares four samples of travertine collected in the lithoid material of the Temple of Hercules (III-IV century B.C.) in San Marco d'Alunzio (Messina) and other four samples of the same...

Crustal contamination and crystal entrapment during polybaric magma evolution at Mt.Somma-Vesuvius volcano, Italy: Geochemical and Sr isotope evidence (2006)

Piochi, M., Ayuso, R. A., De Vivo, B., Somma, R.

New major and trace element analyses and Sr-isotope determinations of rocks from Mt. Somma–Vesuvius volcano produced from 25 ky BP to 1944 AD are part of an extensive database documenting the...

Exactly-solvable models derived from a generalized Gaudin algebra (2005)

Ortiz, G, Somma, R, Dukelsky, J, Rombouts, S

We introduce a generalized Gaudin Lie algebra and a complete set of mutually commuting quantum invariants allowing the derivation of several families of exactly solvable Hamiltonians. Different...

Liquid state NMR simulations of quantum many-body problems (2004)

Negrevergne, C., Somma, R., Ortiz, G., Knill, E., Laflamme, R.

Recently developed quantum algorithms suggest that in principle, quantum computers can solve problems such as simulation of physical systems more efficiently than classical computers. Much remains to...

Introduction to NMR Quantum Information Processing (2002)

Laflamme, R., Knill, E., Cory, D. G., Fortunato, E. M., Havel, T., Miquel, C., ...

After a general introduction to nuclear magnetic resonance (NMR), we give the basics of implementing quantum algorithms. We describe how qubits are realized and controlled with RF pulses, their...

Simulating Physical Phenomena by Quantum Networks (2001)

Somma, R., Ortiz, G., Gubernatis, J. E., Knill, E., Laflamme, R.

Physical systems, characterized by an ensemble of interacting elementary constituents, can be represented and studied by different algebras of observables or operators. For example, a fully polarized...
