Scalable Acceleration of Many-Body Quantum Dynamics via Time-Rescaling
Edson B. de Almeida Filho, Ângelo F. da Silva França, Bertúlio de Lima Bernardo
Fast quantum control is essential to overcome decoherence in contemporary quantum platforms, yet achieving this in many-body systems remains a major challenge. We show that the tim…
Accelerating Feedback-Based Quantum Algorithms through Time Rescaling
L. A. M. Rattighieri, G. E. L. Pexe, B. L. Bernado +1
This work investigates the impact of time rescaling on the performance of Feedback Quantum Algorithms (FQA) and their variant for optimization tasks, FALQON. We introduce TR-FQA an…
Coherent energy fluctuation theorems: theory and experiment
K. Khan, J. Sales Araújo, W. F. Magalhães +2
Heat, work and entropy production: the statistical distribution of such quantities are constrained by the fluctuation theorems (FT), which reveal crucial properties about the natur…
Relating Heat and Entanglement in Strong Coupling Thermodynamics
Bertúlio de Lima Bernardo
Explaining the influence of strong coupling in the dynamics of open quantum systems is one of the most challenging issues in the rapidly growing field of quantum thermodynamics. By…
Unravelling the role of coherence in the first law of quantum thermodynamics
Bertúlio de Lima Bernardo
One of the fundamental questions in the emerging field of quantum thermodynamics is the role played by coherence in energetic processes that occur at the quantum level. Here, we ad…
Probing the reciprocal lattice associated with a triangular slit to determine the orbital angular momentum for a photon
W. C. Soares, A. L. Moura, Askery Canabarro +7
The orbital angular momentum conservation of light reveals different diffraction patterns univocally dependent on the topological charge of the incident light beam when passing thr…
Quantifying interference in multipartite quantum systems
Rejane Alves de Brito, Bertúlio de Lima Bernardo
The characterization of quantum correlations is crucial to the development of new quantum technologies and to understand how dramatically quantum theory departs from classical phys…
Time-rescaled quantum dynamics as a shortcut to adiabaticity
Bertúlio de Lima Bernardo
The design of quantum control methods has been shown to greatly improve the performance of many evolving quantum technologies. To this end, the usage of adiabatic dynamics to drive…
Proposal for a Direct Measurement of the von Neumann Entropy and the Relative Entropy of Coherence
Bertúlio de Lima Bernardo
Quantum coherence is the most distinguished signature of quantum mechanics, also recognized to be an essential resource for many promising quantum technologies, playing a central r…
Experimental realization of a quantum CNOT gate for orbital angular momentum and polarization with linear optical elements
J. H. Lopes, W. C. Soares, B. L. Bernardo +2
We propose and experimentally demonstrate that a Mach-Zehnder interferometer composed of polarized beam splitters and a pentaprism in the place of one of the mirrors works as a lin…
