Maximum speed of quantum gate operation
Lev B. Levitin, Tommaso Toffoli, Zachary Walton
We consider a quantum gate, driven by a general time-dependent Hamiltonian, that complements the state of a qubit and then adds to it an arbitrary phase shift. It is shown that the…
Finite automata models of quantized systems: conceptual status and outlook
Karl Svozil
Since Edward Moore, finite automata theory has been inspired by physics, in particular by quantum complementarity. We review automaton complementarity, reversible automata and the…
Logical equivalence between generalized urn models and finite automata
Karl Svozil
To every generalized urn model there exists a finite (Mealy) automaton with identical propositional calculus. The converse is true as well.
Are simultaneous Bell measurements possible?
Karl Svozil
All experimental tests of Bell-type inequalities and Greenberger-Horne-Zeilinger setups rely on the separate and successive measurement of the terms involved. We discuss possibilit…
What could be more practical than a good interpretation?
Karl Svozil
Quantum mechanics is more than the derivation of straightforward theorems about vector spaces, Hilbert spaces and functional analysis. In order to be applicable to experiment and t…
Quantum information in base n defined by state partitions
Karl Svozil
We define a "nit" as a radix n measure of quantum information which is based on state partitions associated with the outcomes of n-ary observables and which, for n>2, is fundamenta…
