In recent years, quantum computing has made significant strides, particularly in light-based
technology. The introduction of quantum photonic chips has ushered in an era marked by …

We study the memory property of the channels obtained by convex combinations of
Markovian channels that are not necessarily quantum dynamical semigroups (QDSs). In …

We propose an all-optical setup to produce a wide class of X states with an intense laser
beam using spin-orbit modes. In order to characterize such simulated states, we …

The codification of qubits in internal degrees of freedom (DoF) of light as polarization,
transverse modes, and path has received a lot of attention lately. However, the qubit codified …

We develop the formal approach to the angular spectrum transfer in parametric down-
conversion that allows pumping with a structured beam. The scheme is based on an …

We perform an experimental study of quantum discord on spin-orbit modes of an intense
laser beam, analogous to different X states. These modes are prepared through the …

The Solovay-Kitaev theorem allows us to approximate any single-qubit gate to arbitrary
accuracy with a finite sequence of fundamental operations from a universal set of gates …

Quantum coherences are paramount resources for applications, such as quantum-
enhanced light-harvesting or quantum computing, which are fragile against environmental …

We perform an experimental investigation of Quantum Discord with Spin-Orbit X-states.
These states are prepared through the incoherent superposition of different laser beans …

O uso de graus de liberdade da luz na realização de processos e protocolos da informação
e computação quântica tem sido uma área de grande interesse. Em particular, a simulação …
