SUMMARY:Ben Nachman (LBNL) "Modeling final state radiation on a quantum computer"
DESCRIPTION:Abstract: \nParticles produced in high energy collisions that are charged under one of the fundamental forces will radiate proportionally to their charge\, such as photon radiation from electrons in quantum electrodynamics. At sufficiently high energies\, this radiation pattern is enhanced collinear to the initiating particle\, resulting in a complex\, many-body quantum system. Classical Markov Chain Monte Carlo simulation approaches work well to capture many of the salient features of the shower of radiation\, but cannot capture all quantum effects. I will show how quantum algorithms are well-suited for describing the quantum properties of final state radiation. In particular\, I will describe a polynomial time quantum final state shower that accurately models the effects of intermediate spin states similar to those present in high energy electroweak showers. The algorithm is explicitly demonstrated for a simplified quantum field theory on a quantum computer.   One of the greatest challenges for current quantum computers is their significant noise.  I will present new techniques for mitigating both readout noise and gate error noise.  Readout errors are equivalent to detector effects in high energy physics (HEP) and I will show how building a bridge between fields can improve quantum computing in general\, not only for HEP.  For gate error mitigation\, I have proposed a new technique that can achieve a better precision than existing methods with a significantly reduced quantum complexity.   Finally\, I will discuss future directions at the interface between quantum computing and high energy physics.  See 1901.08148\, 1904.03196\, 1910.00129\, and 2003.04941 for details.\n\nhttp://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/99636650720 \nMeeting ID: 996 3665 0720\nOne tap mobile\n+16465588656\,\,99636650720# US (New York)\n+16699006833\,\,99636650720# US (San Jose) \nDial by your location\n+1 646 558 8656 US (New York)\n+1 669 900 6833 US (San Jose)\n+1 253 215 8782 US (Tacoma)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\n+1 346 248 7799 US (Houston)\nMeeting ID: 996 3665 0720\nFind your local number: https://lbnl.zoom.us/u/acaVi4S1v4 \nJoin by SIP\n99636650720@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: 996 3665 0720 \n──────────

SUMMARY:Hitoshi Murayama (LBNL/UCB)"International Linear Collider"
DESCRIPTION:ABSTRACT: \nHaving discovered the Higgs boson without obvious new particles at the Large Hadron Collider\, precision study of the Higgs boson at a Higgs factory is the obvious strategy at the energy frontier. I will review basic motivation and various options for the Higgs factory\, and discuss ILC in this context. I will also discuss some recent political developments.

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──────────

SUMMARY:Alex Kim (LBNL)"Opportunities for Peculiar Velocity Surveys Using DESI\, ZTF-II\, and the Vera C. Rubin Observatory"
DESCRIPTION:ABSTRACT: \nThe motions of galaxies on top of the Hubble expansion\, peculiar velocities\, are a probe of clustering and the growth of structure in the Universe.  For distance indicators\, peculiar velocities manifest themselves as residuals on the Hubble diagram.  Ongoing and upcoming wide-field surveys measuring unprecedented numbers of distance indicators\, together with improvements in the calibration of Type Ia supernova brightnesses\, will provide exquisite precision in the mapping of the peculiar velocity field or more precisely the peculiar distance field.  LBL is well positioned to make distance measurements of sources from DESI\, the Zwicky Transient Facility (ZTF)\, ZTF-II\, and the Rubin Observatory in order to produce compelling constraints on the laws of gravity responsible for the growth of structure. \n  \nhttp://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/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@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: 917 8226 8585 \n──────────

SUMMARY:Daniel Carney (U. Maryland) "Fundamental Physics at the Quantum Limits of Measurement
DESCRIPTION:Abstract:\n40 years ago\, Caves\, Thorne\, and their collaborators asked the question: what are the fundamental quantum limits on the measurement of a small position displacement? The answers to these conceptual questions led to the first direct detection of a gravitational wave by LIGO in 2016. I will review these types of quantum limits and discuss their application to particle physics. In particular\, I will present some new dark matter detection ideas which leverage quantum sensing and control of massive opto-mechanical systems. Current experiments with these devices are already capable of ruling out some exotic dark matter candidates\, and I will focus on these and their next-generation extensions. I will also present some much longer-term applications: a scheme for direct detection of heavy dark matter purely through gravity\, and tabletop experiments testing the quantum nature of gravity.\n\nhttp://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/96617590466 \nMeeting ID: 966 1759 0466\nOne tap mobile\n+16465588656\,\,96617590466# US (New York)\n+16699006833\,\,96617590466# US (San Jose) \nDial by your location\n+1 646 558 8656 US (New York)\n+1 669 900 6833 US (San Jose)\n+1 253 215 8782 US (Tacoma)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\n+1 346 248 7799 US (Houston)\nMeeting ID: 966 1759 0466\nFind your local number: https://lbnl.zoom.us/u/ackakuVouX \nJoin by SIP\n96617590466@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: 966 1759 0466 \n──────────
