Full-magnetic implementation of a classical Toffoli gate
Davide Nuzzi, Leonardo Banchi, Ruggero Vaia +4
The Toffoli gate is the essential ingredient for reversible computing, an energy efficient classical computational paradigm that evades the energy dissipation resulting from Landau…
Single-qubit remote manipulation by magnetic solitons
Alessandro Cuccoli, Davide Nuzzi, Ruggero Vaia +1
Magnetic solitons can constitute a means for manipulating qubits from a distance. This would overcome the necessity of directly applying selective magnetic fields, which is unfeasi…
Dispersionless pulse transport in mass-spring chains: All possible perfect Newton's cradles
Ruggero Vaia
A pulse traveling on a uniform nondissipative chain of masses connected by springs is soon destructured by dispersion. Here it is shown that a proper modulation of the masses a…
Persymmetric Jacobi matrices with square-integer eigenvalues and dispersionless mass-spring chains
Ruggero Vaia, Lidia Spadini
A real persymmetric Jacobi matrix of order whose eigenvalues are is presented, with entries given as explicit functions of . Besides the possible us…
Physics and Derivatives: Effective-Potential Path-Integral Approximations of Arrow-Debreu Densities
Luca Capriotti, Ruggero Vaia
We show how effective-potential path-integrals methods, stemming on a simple and nice idea originally due to Feynman and successfully employed in Physics for a variety of quantum t…
Almost-dispersionless pulse transport in long quasiuniform spring-mass chains: A new kind of Newton's cradle
Ruggero Vaia
Almost-dispersionless pulse transfer between the extremal masses of a uniform harmonic spring-mass chain of arbitrary length can be induced by suitably modifying two masses and the…
