Certification of qubits in the prepare-and-measure scenario with large input alphabet and connections with the Grothendieck constant

open access: yesScientific Reports, 2023
We address the problem of testing the quantumness of two-dimensional systems in the prepare-and-measure (PM) scenario, using a large number of preparations and a large number of measurement settings, with binary outcome measurements. In this scenario, we

Study of the effect of higher-order dispersions on photoionisation induced by ultrafast laser pulses applying a classical theoretical method

open access: yesScientific Reports, 2022
We investigated the effect of higher order dispersion on ultrafast photoionisation with Classical Trajectory Monte Carlo (CTMC) method for hydrogen and krypton atoms.

Quantum correlations in PT -symmetric systems [PDF]

open access: yesQuantum Science and Technology, 2020
We study the dynamics of correlations in a paradigmatic setup to observe PT -symmetric physics: a pair of coupled oscillators, one subject to a gain one to a loss. Starting from a coherent state, quantum correlations (QCs) are created, despite the system

Separation of quantum, spatial quantum, and approximate quantum correlations [PDF]

open access: yesQuantum, 2021
Quantum nonlocal correlations are generated by implementation of local quantum measurements on spatially separated quantum subsystems. Depending on the underlying mathematical model, various notions of sets of quantum correlations can be defined. In this

Hierarchy of quantum correlations under non-Markovian dynamics [PDF]

open access: yesQuantum Information Processing, 2020
We investigate the dynamics of quantum correlation (QC) under the effects of reservoir memory, as a resource for quantum information and computation tasks.

Bounding Temporal Quantum Correlations [PDF]

open access: yesPhysical Review Letters, 2013
Sequential measurements on a single particle play an important role in fundamental tests of quantum mechanics. We provide a general method to analyze temporal quantum correlations, which allows us to compute the maximal correlations for sequential measurements in quantum mechanics.

Polarimetric Quantum-Strong Correlations with Independent Photons on the Poincaré Sphere

open access: yesQuantum Beam Science, 2022
Controllable, quantum-strong correlations of polarization states can be implemented with multi-photon independent states. Polarization-based photonic quantum correlations can be traced back to the overlap of the polarization Stokes vectors on the ...
