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...
Physics and Computation (with Nuclear Spins)
21 May 2020 | | Contributor(s):: Gerardo Ortiz
There is a deep connection between Physics and Computation. Indeed, any computation can be represented as a physical process. In 1981 Richard Feynman raised some provocative questions in connection to the simulation of physical phenomena using a special device called a "Quantum...
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...

Spatial Complexity in Correlated Electronic Systems
08 Jan 2020 | | Contributor(s):: Erica W. Carlson
I will discuss how understanding the formation of these patterns is vital to our understanding of electronic properties and to our eventual technological control of quantum matter. We have defined new paradigms for interpreting and understanding nanoscale electronic textures observed at the...
Many-body Expedition from Semiconductors to Atomic BECs
11 Dec 2019 | | Contributor(s):: Mackillo Kira
Specifically, I will overview how methods of semiconductor quantum optics relate to phenomena in strongly interacting Bose gas. This expedition focuses on the first unitary BEC experiment which demonstrated that a surprisingly large BEC fraction survived a quench from weak to unitary...
The Algebra of Topological Quantum Computing
05 Dec 2019 | | Contributor(s):: Qing Zhang
In this talk, I will discuss some recent results in the theory of tensor categories, motivated by this connection with topological quantum computation.
Universal Variational Quantum Computation
28 Oct 2019 | | Contributor(s):: Jacob Biamonte
We show that the variational approach to quantum enhanced algorithms admits a universal model of quantum computation.
Machine Learning for Quantum Control
28 Oct 2019 | | Contributor(s):: Barry Sanders
We develop a framework that connects reinforcement learning with classical and quantum control, and this framework yields adaptive quantum-control policies that beat the standard quantum limit, inspires new methods for improving quantum-gate design for quantum computing, and suggest new ways to...
On Topological Quantum Computing
28 Oct 2019 | | Contributor(s):: Shawn Xingshan Cui
We give an introduction to the theory of topological quantum computing (TQC), which is an approach to realizing quantum computation with non-Abelian anyons.
Kirkman’s Schoolgirls and Quantum Spin Pairs: A 175 Year Long Thread Through Mathematics and Physics
15 Oct 2019 | | Contributor(s):: A. Ravi. P. Rau
A recreational puzzle posed 175 years ago of 15 schoolgirls to walk three abreast to school for seven days of the week so that no girl sees a friend repeated in her row has links to many areas of mathematics: combinatorics, finite projective geometries, design and coding theory, etc.
Entanglement, Discord and Other Quantum Correlations
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,...
