Nataly Cisternas San Martín and Gabriel Araneda Machuca are the last two master graduates, after two years working under the direction of Professor Aldo Delgado, from Quantum Optics and Quantum Information Division of CEFOP. The investigators showed their thesis at Monday, April 18, in the Faculty of Physics and Mathematics Sciences Lounge. After obtain the best score, they prepare to continue their studies in European research centers.
Gabriel Araneda presented the thesis “Cloning and Telecloning of Quantum States”, investigation he expect be accepted in the Institute of Experimental Physics in Innsbruck, Austria, one of the most advanced teams in the world in quantum computation. He was pre-admitted, and invited to visiting during a week the Institute and presents the result of this research. “I pretend continue with topic of quantum information and quantum optics. Here we are working with photons, but in Austria I could know the trapped ions systems, where ionized atoms interact with electromagnetic fields to control them”. Making the abstract of his work, Gabriel said: “The actual fundaments of quantum mechanics do not allow cloning quantum states. So, we have to search for a method to overcome the limits that the theorem imposes to us. Right now, the best we can do is try to clone information, in a probabilistic way”.
Nataly Cisternas defended “Experimental Implementation of Quantum Probabilistic Teleportation”, an experimental proposal that is currently under preparation, which Nataly expected to continue. “Until now, Quantum Probabilistic Teleportation has not been implemented. That is the reason because we are so interested on make it on our laboratory”. However, her plans cannot go beyond October. “Everything depends of my interview in Germany”, Nataly said. She will present her results in March 26 in the Max Planck Institute for Quantum Optics, in Munich, where she could be admitted to continue her doctorate in Cavity Quantum Electrodynamics (CQED) or Quantum Information Processing. “It is still almost the same, but they are using atoms inside of cavities to make the process”. The studies, as Nataly said, conclude that is possible to correct mistakes in the use of partially entangled channels in quantum processes, throughstate discrimination process. “That means we can correct laboratory mistakes in resources we use, by adding other process to complete the experimental set-up. We can perform more accurate, because we will characterizetheentangled resources and then we will correct it, if it contains errors”.
The CEFOP seal
The pass for CEFOP has been fundamental in the careersof these two new researchers. “It’s very different to work with just one professor, in isolated way, but make it with a team of professionals. The work it is very dynamic”, Gabriel said. “Furthermore, work with CEFOP opened to me the possibility of to be related with international centers”. Nataly described the support of CEFOP as a key: “They always support me to participate in congress and show my work. That kind of experiences helped me to make the contact to go now to Germany”, Nataly emphasized.
