[Harvard-quantum-initiative] CUA Seminar – Tuesday, April 25 – Prof. Eugene Polzik

by Harvard Quantum Initiative

CUA Seminar Tuesday, April 25 3:30 pm, Pfizer Lecture Hall (Mallinckrodt 023) *note time and location change* Prof. Eugene Polzik Niels Bohr Institute, University of Copenhagen Macroscopic objects in the quantum regime Studies of extreme cases within quantum mechanics have always been particularly attractive. How macroscopic can be an object and still demonstrate unique quantum features, such as entanglement? What are the real limits of measurement precision in quantum mechanics? I will review our experiments where macroscopic objects are driven deep into the quantum regime. Generation of an entangled Einstein-Podolsky-Rosen state between distant mechanical and atomic oscillators, the concept of an oscillator with an effective negative mass and progress towards application of those ideas to gravitational wave detection will be reported. Another challenge within quantum physics of macroscopic objects is generation of Fock states corresponding to single quantum excitations of an oscillator. Progress along those lines with Fock states of motion and of a macroscopic atomic ensemble will be presented. Finally, I will briefly review our work towards an atomic quantum simulator. Refreshments provided at 4:30 pm. _______________________________________________ Harvard-quantum-initiative mailing list -- harvard-quantum-initiative(a)lists.fas.harvard.edu To unsubscribe send an email to harvard-quantum-initiative-leave(a)lists.fas.harvard.edu

Kenan Jr. Professor Professor of Molecular and Cellular Physiology and of Energy Science and Engineering Stanford University 1997 Nobel Prize in Physics [cid:image001.jpg@01D96BB0.25AFBAB0] Harvard Physics Colloquium "Entropy, molecular motors, and non-thermal equilibrium statistical physics" Monday, April 24, 2023, 4:30pm (Colloquium Tea served in Jefferson 450 @ 3:30 PM – Please bring your own mug if you have one.) Jefferson 250, 17 Oxford Street, Cambridge, MA and zoom (see the link below) The transport of molecular cargos in neuronal cells is analyzed in the context of new developments in entropy and statistical physics. Our development of very bright optical probes enabled the long-term single tracking of molecular cargos in live neurons. The number of active dynein motors transporting a cargo is found to switch stochastically from one to five dynein motors during the long-range transport in neurons. Our probes allowed the observation of individual molecular steps where the time between single steps is controlled by two temperature-dependent rate constants. This finding suggests that two ATP molecules are hydrolyzed sequentially during each dynein step. The measured fluctuations can be described by a steady-state non-thermal equilibrium temperature, Teff as high as 6× Tcell = 6×310 K, and inversely proportional to the number of motors. Using the Fluctuation Theorem (proven in 1993) is consistent an “uncertainty principle” limit, ΔQ ⋅ ϵ2 ≥ 2kBTeff, where ΔQ = Teff ΔS is the minimum heat entropy needed to achieve an outcome with a given statistical precision. This theorem sets a lower limit to the heat energy needed to achieve a given precision in any physical operation. In the context of intercellular molecular transport, a smaller variance in the displacement of the vesicle demands a greater expenditure of energy. # # # 2023 Lee Historical Lecture in Physics "A random walk into laser cooling, optical trapping and beyond" Tuesday, April 25, 2023, 5:00pm Jefferson 250, 17 Oxford Street, Cambridge, MA and zoom (see the link below) A personal perspective of how laser cooling and optical trapping of atoms and biomolecules was developed. Emphasis will be given on how an elementary understanding of the physics at an undergraduate physics level led to success in initial successes. Once the basic tools of optical molasses and optical trapping were developed, more random walks into polymer physics and biology will be described. # # # Steven Chu is Professor of Physics, Molecular and Cellular Physiology, and Energy Science and Engineering at Stanford University. He received the 1997 Nobel Prize in Physics for laser cooling and trapping of atoms. Other contributions include the first optical tweezers manipulation of biomolecules, precision atom interferometry based on optical pulses of light, and single molecule FRET of biomolecules tethered to surfaces. He is now developing and applying new methods in molecular biology and medical imaging, materials science, and batteries. Previously he was U.S. Secretary of Energy, where he began ARPA-E, the Energy Innovation Hubs, and was tasked by President Obama to help BP stop the Macondo Oil spill. Previously, he was director of Lawrence Berkeley National Laboratory and Professor of Physics and Applied Physics at Stanford, and help initiate Bio-X, that linked the physical and biological sciences with engineering and medicine. Before Stanford, he was a department head at Bell Laboratories.

HQI Special Seminar - Monday, 4/10 at 4:00pm - Uma Girish

by Ploucha, Clare

HQI Special Seminar – Uma Girish (Princeton) Monday, April 10, 2023 4:00 – 4:45 PM Pierce 209 Title: Space-Bounded Quantum Computation & Quantum versus Classical Separations The study of space-bounded quantum computation is important, as quantum computers in the near future are likely to have limited memory. We present space-efficient methods for eliminating intermediate measurements in quantum algorithms and establish fascinating connections of this problem to matrix powering and derandomization. Understanding the relative advantages of quantum over classical computation is a fascinating problem. While quantum algorithms are widely believed to outperform classical ones, there are very few settings in which this has been proved without assumptions. Query and communication complexity are striking examples of such settings. We study the advantages of quantum over classical in these settings and show improved quantum versus classical separations. If you would like to meet with Uma Girish during her visit on April 10-11, please contact cploucha(a)fas.harvard.edu<mailto:cploucha@fas.harvard.edu>

Harvard Quantum Information Group Meeting this Thursday at 4:30 pm

by Cotler, Jordan Saul

Hi everyone, The Harvard Quantum Information Group Meeting will have a special guest this Thursday, April 13th at 4:30 pm in Jefferson 250. David Gosset, from the University of Waterloo and Perimeter Institute, will be speaking. Please see the title and abstract below. Title: How to simulate quantum measurement without computing marginals Abstract: In this work we provide new techniques for a fundamental and ubiquitous task: simulating measurement of a quantum state in the standard basis. Our algorithms reduce the sampling task to computing poly(n) amplitudes of n-qubit states; unlike previously known techniques they do not require computation of marginal probabilities. First we consider the case where the state of interest is the output state of an m-gate quantum circuit U. We propose an exact sampling algorithm which involves computing O(m) amplitudes of n-qubit states generated by subcircuits of U spanned by the first t=1,2,…,m gates. We show that our algorithm can significantly accelerate quantum circuit simulations based on tensor network contraction methods or low-rank stabilizer decompositions. Second, we consider the case in which ψ is the unique ground state of a local Hamiltonian with a spectral gap that is lower bounded by an inverse polynomial function of n. We prove convergence guarantees for a simple Metropolis-Hastings Markov Chain as well as a more involved continuous-time Markov chain that is related to the so-called fixed node Hamiltonian approach from the quantum Monte Carlo community. This talk is based on joint works arXiv:2112.08499 and arXiv:2207.07044 with Sergey Bravyi, Giuseppe Carleo, and Yinchen Liu. Hope to see you all there. Sincerely, Jordan Cotler

FW: EE Seminar: Today! Oskar Painter (Caltech), "Engineering of Superconducting Circuits for Quantum Simulation"

by Ploucha, Clare

-------- Forwarded Message -------- Subject: [ee-faculty] [EE-Seminar] EE Seminar: Today! Oskar Painter (Caltech), "Engineering of Superconducting Circuits for Quantum Simulation" Date: Fri, 7 Apr 2023 08:00:00 -0400 From: Brenn, Jess <jbrenn(a)g.harvard.edu><mailto:jbrenn@g.harvard.edu> Reply-To: jbrenn(a)g.harvard.edu<mailto:jbrenn@g.harvard.edu> To: EECS ee-seminars <ee-seminars(a)eecs.harvard.edu><mailto:ee-seminars@eecs.harvard.edu> CC: SEAS ee-faculty <ee-faculty(a)seas.harvard.edu><mailto:ee-faculty@seas.harvard.edu>, SEAS EE-Gradstudents <ee-gradstudents(a)seas.harvard.edu><mailto:ee-gradstudents@seas.harvard.edu>, seas-ee-researchers <seas-ee-researchers(a)g.harvard.edu><mailto:seas-ee-researchers@g.harvard.edu> Harvard John A. Paulson School of Engineering and Applied Sciences ELECTRICAL ENGINEERING SEMINAR Friday, April 7 at 1pm | SEC 1.402 "Engineering of Superconducting Circuits for Quantum Simulation" Oskar Painter, Professor of Applied Physics and Physics, Caltech Abstract: While the majority of engineerable many-body systems, or quantum simulators, consist of particles on a lattice with local interactions, quantum systems featuring long-range interactions are particularly challenging to model and interesting to study due to the rapid spatio-temporal growth of quantum entanglement and correlations. In my talk I will present a scalable quantum simulator architecture based on a linear array of superconducting qubits locally connected to an extensible photonic-bandgap metamaterial. The metamaterial acts both as a quantum bus mediating qubit-qubit interactions, and as a readout channel for multiplexed qubit-state measurement. As an initial demonstration, we realize a 10-qubit simulator of the one-dimensional Bose-Hubbard model with in situ tunability of both the hopping range and the on-site interaction. I will present how we characterize the Hamiltonian of the system using a measurement-efficient protocol based on quantum many-body chaos, and use a similar technique to study the many-body quench dynamics of the system, revealing through global bit-string statistics the predicted crossover from integrability to ergodicity as the hopping range increases. I will also discuss how the metamaterial quantum bus architecture can be extended to two-dimensional lattice systems and used to generate a wide range of qubit interactions, expanding the accessible Hamiltonians for analog quantum simulation and increasing the flexibility in implementing quantum circuits for gate-based computations. Bio: Oskar Painter received his Bachelor of Applied Science degree in Electrical Engineering from the University of British Columbia in 1994, his Master of Science degree from the California Institute of Technology in 1995, and his Ph.D. in Electrical Engineering from the California Institute of Technology in 2001. He joined the faculty at the California Institute of Technology in 2002, where he is now the John G. Braun Professor of Applied Physics and Professor of Physics. Prof. Painter's current research interests are in studying the quantum properties of mechanical systems, the development of hybrid superconducting quantum circuits for quantum information processing applications and quantum computing. He is currently on-leave from Caltech, leading the Amazon Web Services quantum computing hardware team. Speaker's Research Interests: Prof. Painter's current research interests are in studying the quantum properties of mechanical systems, the development of hybrid superconducting quantum circuits for quantum information processing applications and quantum computing. -- Jessica Brenn | Administrative Coordinator for Academic Operations Applied Math, Computer Science, Electrical Engineering Harvard John A.
