SUMMARY:Alexander Stibor (LBNL) "QIS with Coherent Electrons: Quantum Sensors\, Superconducting Emitters\, Signal Transmission and Decoherence Studies"
DESCRIPTION:Abstract:  \nCreating\, manipulating and detecting coherent\, entangled quantum states and isolating quantum systems from decoherence is at the heart of future quantum information science technologies. With the rise of novel instruments in quantum electronics\, the coherent emission and control of free electron beams become relevant in various fields of physics. In this presentation\, I will give an overview of the research performed in Tuebingen (Germany) and at the LBL Molecular Foundry where we are currently realizing the QUINTESSENCE QIS project. The aim is to use the matter-waves of electrons\, superconductivity and correlation detection to develop novel quantum techniques and applications in sensor technology\, electron microscopy and signal transmission. Such experiments are demonstrated with a biprism electron interferometer. We realized a correlation sensor for electromagnetic and vibrational perturbations and a secure signal transmission method by matter-wave modulation. Furthermore\, I will present a characterization setup for a superconducting niobium nano-tip field emitter. This beam source has the potential to emit entangled electron pairs that open up new modes in quantum information\, quantum metrology and electron spectroscopy. To achieve long coherence times in future quantum instrumentation\, a basic understanding of decoherence\, being the transition from a quantum to a classical state\, is crucial. We studied experimentally the Coulomb-induced decoherence of electrons in a superposition state and were able to rule out three of four current theoretical approaches in the literature. It allows the development of novel non-invasive techniques for quantum electron microscopy.http://physics.lbl.gov/rpm/index.php/events/ \nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks. \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/94679537616 \nMeeting ID: 946 7953 7616\nOne tap mobile\n+16699006833\,\,94679537616# US (San Jose)\n+12532158782\,\,94679537616# US (Tacoma) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 253 215 8782 US (Tacoma)\n+1 346 248 7799 US (Houston)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 946 7953 7616\nFind your local number: https://lbnl.zoom.us/u/abKfGWf6S \nJoin by SIP\n94679537616@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 946 7953 7616 \n──────────
