We derive a general approximate solution to the problem of minimizing the conditional entropy of a qudit-qubit system resulting from a local measurement on the qubit, which is valid for general entropic forms and becomes ...

We examine, in correlated mixed states of qudit-qubit systems, the set of all conditional qubit states that can be reached after local measurements at the qudit based on rank-1 projectors. While for a similar measurement ...

In this work we performed two experiments to observe the fractional topological phases in two qudits photonic systems. The qudits are encoded in the transverse position degree of freedom of photon pairs generated by the ...

In this thesis, we explore the properties of photons generated by parametric down-conversion (PDC) and entangled in continuous variables of transverse momentum, with the aim of using this degree of freedom for developing ...

Repeatedly in the field of Quantum Information Science (QIS) it’s essentially required of physical systems the quantification concerning its quantum phenomena, such as Quantum Coherence (QC) relying in quantum superposition ...

We present a method for preparing arbitrary pure states of spatial qudits, namely, D-dimensional ($D\geqslant 2$) quantum systems carrying information in the transverse momentum and position of single photons. For this ...
