Multifold behavior of the information transmission by the quantum 3-switch
Lorenzo M. Procopio, Francisco Delgado, Marco Enriquez +1
We uncover new behaviors of the transmission of information by three quantum channels in superposition of causal orders subject to some level of noise. We find that the transmissio…
Sending classical information via three noisy channels in superposition of causal orders
Lorenzo M. Procopio, Francisco Delgado, Marco Enriquez +2
In this work, we study the transmission of classical information through three completely depolarizing channels in superposition of different causal orders. We thus introduce the q…
Communication Enhancement Through Quantum Coherent Control of Channels in an Indefinite Causal-order Scenario
Lorenzo M. Procopio, Francisco Delgado, Marco Enriquez +2
In quantum Shannon theory, transmission of information is enhanced by quantum features. Up to very recently, the trajectories of transmission remained fully classical. Recently, a…
Entanglement of three-qubit random pure states
Marco Enriquez, Francisco Delgado, Karol Życzkowski
We study non-local properties of generic three-qubit pure states. First, we obtain the distributions of both the coefficients and the only phase in the five-term decomposition of A…
Exactly solvable one-qubit driving fields generated via non-linear equations
Marco Enriquez, Sara Cruz y Cruz
Using the Hubbard representation for we write the time-evolution operator of a two-level system in the disentangled form. This allows us to map the corresponding dynamical…
SU(1,1) and SU(2) Approaches to the Radial Oscillator: Generalized Coherent States and Squeezing of Variances
Oscar Rosas-Ortiz, Sara Cruz y Cruz, Marco Enriquez
It is shown that each one of the Lie algebras su(1,1) and su(2) determine the spectrum of the radial oscillator. States that share the same orbital angular momentum are used to con…
Minimal Renyi-Ingarden-Urbanik entropy of multipartite quantum states
Marco Enriquez, Zbigniew Puchała, Karol Życzkowski
We study the entanglement of a pure state of a composite quantum system consisting of several subsystems with levels each. It can be described by the Rényi-Ingarden-Urbanik ent…
Kronecker product in terms of Hubbard operators and the Clebsch-Gordan decomposition of SU(2)xSU(2)
Oscar Rosas-Ortiz, Marco Enriquez
We review the properties of the Kronecker (direct, or tensor) product of square matrices in terms of Hubbard operators. In its simplest form, a Hubba…
