Classical limit and quantum logic
(Springer/Plenum Publishers, 2018-02)
The analysis of the classical limit of quantum mechanics usually focuses on the state of the system. The general idea is to explain the disappearance of the interference terms of quantum states appealing to the decoherence ...
Quantum state tomography and quantum logical operations in a three qubits NMR quadrupolar system
(WORLD SCIENTIFIC PUBL CO PTE LTDSINGAPORE, 2013-08-02)
In this work, we present an implementation of quantum logic gates and algorithms in a three effective qubits system, represented by a (I = 7/2) NMR quadrupolar nuclei. To implement these protocols we have used the strong ...
Quantum computational logic with mixed states
(Wiley VCH Verlag, 2013-01)
In this paper we solve the problem how to axiomatize a system of quantum computational gates known as the Poincaré irreversible quantum computational system. A Hilbert-style calculus is introduced obtaining a strong ...
Physical Properties as Modal Operators in the Topos Approach to Quantum Mechanics
In the framework of the topos approach to quantum mechanics we give a representation of physical properties in terms of modal operators on Heyting algebras. It allows us to introduce a classical type study of the mentioned ...
A discussion on particle number and quantum indistinguishability
The concept of individuality in quantum mechanics shows radical differences from the concept of individuality in classical physics, as E. Schrödinger pointed out in the early steps of the theory. Regarding this fact, some ...
Semilattices global valuations in the topos approach to quantum mechanics
In the framework of the topos approach to quantum mechanics a kind of global valuation is introduced and studied. It allows us to represent certain features related to the logical consequences of properties about quantum ...
The Formalism of Generalized Contexts and Decay Processes
The formalism of generalized contexts for quantum histories is used to investigatethe possibility to consider the survival probability as the probability of no decay property at a given time conditional to no decay property ...

Quantum state tomography of polarization states - an exploration of quantum logic gates

Typing Quantum Superpositions and Measurement
We propose a way to unify two approaches of non-cloning in quantum lambda-calculi. The first approach is to forbid duplicating variables, while the second is to consider all lambda-terms as algebraic-linear functions. We ...
