  4. Advances in Computational and Quantum Imaging Workshop

    28 Jan 2020 |

    The purpose of the workshop is to bring different communities together, review recent theoretical and experimental advances and explore synergetic collaborations. The workshop aligns well with the significant investments in quantum technologies through the National Quantum Initiative in the...

  5. Beyond the Heisenberg Uncertainty Principle in the Negative Mass Reference Frame

    07 Apr 2016 | | Contributor(s):: Eugene Polzik

    Measurements of one quadrature of an oscillator with precision beyond its vacuum state uncertainty have occupied a central place in quantum physics for decades. A squeezed state of one of the quadratures is a prominent example of a state which provides such precision. One of the first proposals...

  6. Chilling with Light: Exploring the Cool Science of Laser Cooling

    29 Nov 2023 | | Contributor(s):: Hadiseh Alaeian

  7. Coherent Nonlinear Optical Propagation Processes in Hyperbolic Metamaterials

    08 Jun 2017 | | Contributor(s):: Alexander K. Popov

    Coherence and interference play an important role in classic and quantum physics. Processes to be employed can be significantly enhanced and the unwanted ones suppressed through the deliberately tailored constructive and destructed interference at quantum transitions and at nonlinear optical...

  10. Designing a NISQ Reservoir with Maximal Memory Capacity for Volatility Forecasting

    28 Oct 2020 | | Contributor(s):: Samudra Dasgupta

    In this talk, we lay out the systematic design considerations for using a NISQ reservoir as a computing engine. We then show how to experimentally evaluate the memory capacity of various reservoir topologies  (using IBM-Q’s Rochester device) to identify the configuration with maximum...

  11. Discrete Nonlinear Optimization: Modeling and Solutions via Novel Hardware and Decomposition Algorithms

    07 Feb 2024 | | Contributor(s):: David E. Bernal Neira

    Optimization problems arise in different areas of Logistics, Manufacturing, Process Systems Engineering (PSE), and Energy Systems Engineering, and solving these problems efficiently is essential for addressing important industrial applications.Quantum computers have the potential to efficiently...

  12. Electronic Structure Theory

    30 Nov 2023 | | Contributor(s):: Adam Wasserman

  13. Entanglement, Discord and Other Quantum Correlations

    15 Oct 2019 | | Contributor(s):: A. Ravi. P. Rau

    We will discuss states and operators of two (or more) qubits, and higher dimensional "qudits," from the symmetry groups and algebras pertaining to them. The study of the time evolution of such systems can gain much from the insights and techniques provided by such considerations,...

  14. Excited State Spectroscopy of a Quantum Dot Molecule

    11 Jan 2013 | | Contributor(s):: Muhammad Usman

    Atomistic electronic structure calculations are performed to study the coherent inter-dot couplings of the electronic states in a single InGaAs quantum dot molecule. The experimentally observed excitonic spectrum by Krenner et al (Phys. Rev. Lett. 94 057402, 2005) is quantitatively reproduced,...

  15. Exploring Synthetic Quantum Materials in Superconducting Circuits

    30 Apr 2020 |

    Superconducting circuits have emerged as a competitive platform for quantum computation, satisfying the challenges of controllability, long coherence and strong interactions. I will show our recent experiments to apply this toolbox to the exploration of strongly correlated quantum materials made...

  16. Frequency Bin Quantum Photonics

    11 Jul 2019 | | Contributor(s):: Andrew M Weiner

    In this talk I discuss recent advances in manipulation and measurement of quantum states encoded and entangled in the photonic frequency degree of freedom or hyperentangled in time and frequency degrees of freedom. Although the perspective is primarily experimental, I will also attempt to...

  17. Full-Wave Modeling of Microwave Frequency Single Photon Sources

    08 Jul 2021 | | Contributor(s):: Thomas Roth

    In this talk, we present preliminary results on how fully classical computational electromagnetics methods can be leveraged to more fully characterize the performance of single photon sources. To make the development more concrete, we specifically focus on modeling a microwave frequency single...
