The Hahn Quantum Variational Calculus [PDF]

open access: yesJournal of Optimization Theory and Applications, 2010
We introduce the Hahn quantum variational calculus. Necessary and sufficient optimality conditions for the basic, isoperimetric, and Hahn quantum Lagrange problems, are studied. We also show the validity of Leitmann's direct method for the Hahn quantum variational calculus, and give explicit solutions to some concrete problems.

Quantum stochastic calculus and quantum nonlinear filtering

open access: yesJournal of Multivariate Analysis, 1992
A *-algebraic indefinite structure of quantum stochastic (QS) calculus is introduced and a continuity property of generalized nonadapted QS integrals is proved under the natural integrability conditions in an infinitely dimensional nuclear space. The class of nondemolition output QS processes in quantum open systems is characterized in terms of the QS ...

Generalized Ostrowski-Gruss Like Inequality on Time Scales [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2023
In this paper, we present a generalization of the Montgomery Identity to various time scale versions, including the discrete case, continuous case, and the case of quantum calculus.

Application of Quantum Process Calculus to Higher Dimensional Quantum Protocols [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
We describe the use of quantum process calculus to describe and analyze quantum communication protocols, following the successful field of formal methods from classical computer science.

Depicting qudit quantum mechanics and mutually unbiased qudit theories [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
We generalize the ZX calculus to quantum systems of dimension higher than two. The resulting calculus is sound and universal for quantum mechanics. We define the notion of a mutually unbiased qudit theory and study two particular instances of these ...

Quantum Control in the Unitary Sphere: Lambda-S1 and its Categorical Model [PDF]

open access: yesLogical Methods in Computer Science, 2022
In a recent paper, a realizability technique has been used to give a semantics of a quantum lambda calculus. Such a technique gives rise to an infinite number of valid typing rules, without giving preference to any subset of those.

Qutrit Dichromatic Calculus and Its Universality [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
We introduce a dichromatic calculus (RG) for qutrit systems. We show that the decomposition of the qutrit Hadamard gate is non-unique and not derivable from the dichromatic calculus.

Covariantization of quantized calculi over quantum groups [PDF]

open access: yesMathematica Bohemica, 2020
We introduce a method for construction of a covariant differential calculus over a Hopf algebra $A$ from a quantized calculus $da=[D,a]$, $a\in A$, where $D$ is a candidate for a Dirac operator for $A$.

Superdense Coding with GHZ and Quantum Key Distribution with W in the ZX-calculus [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
Quantum entanglement is a key resource in many quantum protocols, such as quantum teleportation and quantum cryptography. Yet entanglement makes protocols presented in Dirac notation difficult to verify.
