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──────────
