Localized Nitrogen-Vacancy centers generated by low-repetition rate fs-laser pulses
Charlie Oncebay, Juliana M. P. Almeida, Gustavo F. B. Almeida +2
Among hundreds of impurities and defects in diamond, the nitrogen-vacancy (NV) center is one of the most interesting to be used as a platform for quantum technologies and nanosensi…
Spin coherence mapping of NV centers in diamond
Lucas Nunes Sales de Andrade, Charlie Oncebay Segura, Sérgio Ricardo Muniz
In recent years, nitrogen-vacancy (NV) color centers in diamond have become excellent solid-state quantum sensors due to their electronic spin properties. Especially for their easy…
Measurements of spin-coherence in NV centers for diamond-based quantum sensors
Lucas Nunes Sales de Andrade, Charlie Oncebay Segura, Sérgio Ricardo Muniz
One of the biggest challenges to implement quantum protocols and quantum information processing (QIP) is achieving long coherence times, usually requiring systems at ultra-low temp…
Diamond-based optical vector magnetometer
Charlie Oncebay Segura, Sérgio Ricardo Muniz
We describe here the construction and characterization of a high-resolution optical magnetometer to measure the full vector magnetic field on an ultrathin layer near the surface of…
Benchmark of the Schmiedl-Seifert optimal protocol with reduced dissipated work and fluctuations in optical tweezers
Thalyta Tavares Martins, André H. A. Malavazi, Lucas Prado Kamizaki +4
Finite-time thermodynamic transformations generally dissipate energy, as required by the Second Law, so identifying and investigating energetically optimal processes remain relevan…
Josephson-like oscillations in toroidal spinor Bose-Einstein condensates: a prospective symmetry probe
Mário H. Figlioli Donato, Sérgio R. Muniz
Josephson junctions are essential ingredients in the superconducting circuits used in many existing quantum technologies. Additionally, ultracold atomic quantum gases have also bec…
