Controlling the various degrees‐of‐freedom (DoFs) of structured light at both quantum and
classical levels is of paramount importance in optics. It is a conventional paradigm to treat …

Vector beams, non-separable in spatial mode and polarisation, have emerged as enabling
tools in many diverse applications, from communication to imaging. This applicability has …

We propose an all-optical experiment to quantify non-Markovianity in an open quantum
system through quantum coherence of a single quantum bit. We use an amplitude damping …

We introduce both a theoretical and an experimental scheme for simulating a quantum
thermal engine through an all-optical approach, with the behavior of the working substance …

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 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 …

We introduce a proposal to prepare spin-obit maximally discordant mixed states by a linear
optical circuit, with quantum bits (qubits) encoded in the polarization and transverse mode …

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 …

In this work, we propose the use of geometric phases obtained for both polarization and
Hermite–Gaussian first-order transverse modes to create controlled phase gates. We …
