Quantum Simulators and Quantum Repeaters [PDF]

open access: yesFortschritte der Physik, 2000
It is shown that a photon from a non-maximal singlet, obtained by a controlled entanglement of two downconverted photon pairs, can be entangled with a photon from another such singlet. As a result the other photons from the singlets appear in a singlet state with an event probability arbitrary close to one.

Quantum automata and quantum grammars

open access: yesTheoretical Computer Science, 2000
To study quantum computation, it might be helpful to generalize structures from language and automata theory to the quantum case. To that end, we propose quantum versions of finite-state and push-down automata, and regular and context-free grammars. We find analogs of several classical theorems, including pumping lemmas, closure properties, rational ...

Quantum Dissipation and Quantum Groups [PDF]

open access: yesAnnals of Physics, 1995
We discuss the r le of quantum deformation of Weyl-Heisenberg algebra in dissipative systems and finite temperature systems. We express the time evolution generator of the damped harmonic oscillator and the generator of thermal Bogolubov transformations in terms of operators of the quantum Weyl-Heisenberg algebra. The quantum parameter acts as a label

Quantumness beyond quantum mechanics [PDF]

open access: yesJournal of Physics: Conference Series, 2012
Bohmian mechanics allows us to understand quantum systems in the light of other quantum traits than the well-known ones (coherence, diffraction, interference, tunneling, discreteness, entanglement, etc.). Here the discussion focusses precisely on two of these interesting aspects, which arise when quantum mechanics is though within this theoretical ...

A variational eigenvalue solver on a photonic quantum processor [PDF]

open access: yesNature Communications, 2013
Quantum computers promise to efficiently solve important problems that are intractable on a conventional computer. For quantum systems, where the physical dimension grows exponentially, finding the eigenvalues of certain operators is one such intractable

Quantum Logic for Quantum Computers

open access: yesInternational Journal of Theoretical Physics, 2000
The following results obtained within a project of finding algebra of states in a general purpose quantum computer are reported: 1. all operations of an orthomodular lattice, including the identity, are five-fold defined ; 2. there are non-orthomodular models for both quantum and classical logics ; 3.
