-dimensional discrete Fourier transform via bosonic Hamiltonian
Edgar Barriga, Camila Muñoz, Alejandro Muñoz +4
The discrete Fourier transform (DFT) underpins many classical algorithms and is a fundamental unitary operator for quantum information processing. Implementing the -dimensional…
Analytic Evolution for Complex Coupled Tight-Binding Models: Applications to Quantum Light Manipulation
Santiago Rojas-Rojas, Camila Muñoz, Edgar Barriga +3
We present analytic solutions to the evolution in generalized tight-binding models, which consider complex first-neighbor couplings with equal amplitude and arbitrary phases. Our f…
Non-Markovianity in High-Dimensional Open Quantum Systems using Next-generation Multicore Optical Fibers
Santiago Rojas-Rojas, Daniel Martínez, Kei Sawada +5
With the advent of quantum technology, the interest in communication tasks assisted by quantum systems has increased both in academia and industry. Nonetheless, the transmission of…
Optimal conditions for multiplexing information into ring-core optical fibers
Santiago Rojas-Rojas, Gustavo Cañas, Gabriel Saavedra +3
In optical communications, space-division multiplexing is a promising strategy to augment the fiber network capacity. It relies on modern fiber designs that support the propagation…
Manipulation of Multimode Squeezing in a Coupled Waveguide Array
S. Rojas-Rojas, E. Barriga, C. Muñoz +2
We present a scheme for generating and manipulating three-mode squeezed states with genuine tripartite entanglement by injecting single-mode squeezed light into an array of coupled…
Quantum localized states in photonic flat-band lattices
Santiago Rojas-Rojas, Luis Morales-Inostroza, Rodrigo A. Vicencio +1
The localization of light in flat-band lattices has been recently proposed and experimentally demonstrated in several configurations, assuming a classical description of light. Her…
Observation of dipolar transport in one-dimensional photonic lattices
Camilo Cantillano, Luis Morales-Inostroza, Bastián Real +4
We experimentally study the transport prop- erties of dipolar and fundamental modes on one di- mensional (1D) coupled waveguide arrays. By carefully modulating a wide optical beam,…
Expansion of a wave-packet in lattices with disorder and nonlinearity
Uta Naether, Santiago Rojas-Rojas, Alejandro J. Martinez +6
We show, theoretically and experimentally, the counterintuitive result that an increase of disorder can result in an enhanced spreading of an initially localized excitation. Moreov…
Nonlinear localized modes in dipolar Bose-Einstein condensates in optical lattices
S. Rojas-Rojas, R. A. Vicencio, M. I. Molina +1
The modulational instability and discrete matter wave solitons in dipolar BEC, loaded into a deep optical lattice, are investigated analytically and numerically. The process of mod…
