In This Workshop

1. Looking for Fossils of the Big Bang in Molecular Spectra

   Online Presentations | 05 Jun 2019 | Contributor(s): Eric A. Cornell

   I will talk about precision measurement. We will see that the humble two-atom molecule should be thought of as an ultrahigh electric-field laboratory.

2. Peculiar Corners of Hilbert Space where Strange States Lie

   Online Presentations | 01 Jun 2019 | Contributor(s): Chris H Greene

   This talk will summarize some of the peculiar states that have been found, which relate in some cases to Efimov physics, and in other cases to ultra-long-range Rydberg molecules, sometimes referred to as ‘trilobite’ or ‘butterfly’ molecules and their ghosts.

3. Topological Materials as Platforms for New Particles and Electromagnetic Responses

   Online Presentations | 06 Jun 2019 | Contributor(s): Joel Moore

   We then turn to how topological Weyl and Dirac semimetals can show unique electromagnetic responses; we argue that in linear response the main observable effect solves an old problem via the orbital moment of Bloch electrons, and how in nonlinear optics there should be a new quantized effect,...

4. Spin-Helical Particles: an Enabling Platform for Quantum Matter and Quantum Technologies

   Online Presentations | 05 Jun 2019 | Contributor(s): Yong P. Chen

   Spin is one of the most fundamental quantum properties of particles. In this talk I will describe our experimental studies of “spin-helical” particles (analogous to neutrinos with spin locked to the momentum, but for electrons and atoms) as a powerful platform to realize novel...

5. Can Plasmonics Help Outpace Quantum Decoherence?

   Online Presentations | 07 Jun 2019 | Contributor(s): Vladimir M. Shalaev

   We discuss an unorthodox way to overcome quantum decoherence by using plasmonics that can speed up quantum processes to the extent that they outpace and thus become immune to decoherence.

6. Frequency Domain Quantum Photonics

   Online Presentations | 14 Jun 2019 | Contributor(s): Andrew M Weiner

   Entanglement and encoding in discrete frequency bins – essentially a quantum analogue of wavelength-division multiplexing – represents a relatively new degree of freedom for quantum information with photons. In this talk I describe experiments demonstrating manipulation and...

7. Discovery of Spin-Vortex-Crystal Magnetic Order in Ni- and Co- Doped CaKFe4As4

   Online Presentations | 20 Jun 2019 | Contributor(s): Paul C. Canfield

   The discovery of CaFe2As2 in 2008 revealed the extreme member of the AEFe2As2 family AE = Ba, Sr, Ca. CaFe2As2 has the smallest c-lattice parameter, manifests a strongly coupled, first-order, structural/magnetic phase transition and can be coaxed into a collapsed tetragonal phase transition,...

8. Aharonov-Bohm Interference of Fractional Quantum Hall Edge Modes

   Online Presentations | 20 Jun 2019 | Contributor(s): Michael J. Manfra

   The braiding statistics of certain fractional quantum Hall states can be probed via interferometry of their edge states. Practical difficulties – including loss of phase coherence – make this a challenging task. We demonstrate the operation of a small Fabry-Perot interferometer in...

9. Certified Quantum Measurement of Majorana Fermions and New Entangled Quantum Probes

   Online Presentations | 20 Jun 2019 | Contributor(s): Gerardo Ortiz

10. Opening Remarks

    Online Presentations | 03 Jul 2019 | Contributor(s): Yong P. Chen

11. Engineering a Superconducting Quantum Computer

    Online Presentations | 30 Jun 2019 | Contributor(s): Zijun "Jimmy" Chen

    In this talk, I will discuss Google’s efforts to tackle these challenges and engineer a large scale quantum processor. I will also show our latest results on achieving high fidelity single and two qubit operations on these devices, and discuss the prospects for achieving quantum supremacy.

12. Quantum Matter & Atomic Clocks

    Online Presentations | 11 Jul 2019 | Contributor(s): Jun Ye

    Relentless pursuit of spectroscopy resolution has been a key driving force for important scientific and technological breakthroughs, including the invention of laser and the creation of cold atomic matter. The most stable lasers now maintain optical phase coherence over tens of seconds....

13. Quantum Information and Computation for Quantum Chemistry

    Online Presentations | 14 Aug 2019 | Contributor(s): Sabre Kais

    Recently, Purdue University received $1.5 million in National Science Foundation (NSF) funding to establish a research center to study quantum information science. The Center for Quantum Information and Computation for Chemistry will investigate information techniques used to gain novel...

14. Quantum Algorithmic Breakeven: on Scaling Up with Noisy Qubits

    Online Presentations | 21 Aug 2019 | Contributor(s): Daniel Lidar

    In this talk I will argue in favor of a different criterion I call "quantum algorithmic breakeven," which focuses on demonstrating an algorithmic scaling improvement in an error-corrected setting over the uncorrected setting. I will present evidence that current experiments with...
