Enhancing nonclassical properties of quantum states of light using linear optics

E. P. Mattos, A. Vidiella-Barranco

In this letter, we present a simple and versatile scheme for enhancing the nonclassical properties of light states using only linear optics and photodetectors. By combining a coher…

Parametrically driving a quantum oscillator into exceptionality

C. A. Downing, A. Vidiella-Barranco

The mathematical objects employed in physical theories do not always behave well. Einstein's theory of space and time allows for spacetime singularities and Van Hove singularities…

The quantum maxima for the basic graphs of exclusivity are not reachable in Bell scenarios

Lucas E. A. Porto, Rafael Rabelo, Marcelo Terra Cunha +1

A necessary condition for the probabilities of a set of events to exhibit Bell nonlocality or Kochen-Specker contextuality is that the graph of exclusivity of the events contains i…

Wigner and friends, a map is not the territory! Contextuality in multi-agent paradoxes

Sidiney B. Montanhano

Multi-agent scenarios, like Wigner's friend and Frauchiger-Renner scenarios, can show contradictory results when a non-classical formalism must deal with the knowledge between agen…

Controllable Fano-type optical response and four-wave mixing via magnetoelastic coupling in a opto-magnomechanical system

Amjad Sohail, Rizwan Ahmed, Jia-Xin Peng +4

We analytically investigate the Fano-type optical response and four-wave mixing (FWM) process by exploiting the magnetoelasticity of a ferromagnetic material. The deformation of th…

Two coupled qubits under the influence of a minimal, phase-sensitive environment

G. L. Deçordi, A. Vidiella-Barranco

In this work, we investigate the influence of a minimal, phase-sensitive environment on a system of two coupled qubits. The environment is constituted by a single-mode field initia…

Quantum Mechanics on Sharply Bent Wires via Two-Interval Sturm-Liouville Theory

João Paulo M. Pitelli, Ricardo A. Mosna, Felipe Felix Souto

We study quantum mechanics on a curved wire by approximating the physics around the curved region by three parameters coming from the boundary conditions given by the two interval…
