Investigating the impact of a laser’s noise property on qubits
When Institute for Quantum Computing (IQC) Research Associate Matthew Day had his lab temporarily closed during the COVID-19 pandemic, the experimentalist found himself at some loose ends. What’s an experimentalist to do without his equipment? For Day, it was a chance for him to ask questions he’d been thinking about for a while. Specifically, Day wanted to know: how does equipment in the lab affect experiments?

Generating k EPR-pairs from an n-party resource state
IQC Math CS Seminar - featuring Mario Szegedy, Rutgers University
Motivated by quantum network applications over classical channels, we initiate the study of n-party resource states from which LOCC protocols can create EPR-pairs between any k disjoint pairs of parties. ...
Complexity and Clarity for Kitaev Candidate Materials
Chemistry Seminar Series – Steve Winter, Wake Forest University
Host: A. Wei Tsen
Quantum materials represent a broad class of systems whose experimental response relies directly on entanglement between their underlying degrees of freedom. Modeling of such materials presents a variety of challenges related to a disparate variety of complex behaviours that manifest at different energy scales, and a typical sensitivity of responses to model parameters. In this field, first-principles approaches often provide a vital bridge between experiments and theoretical models. In this talk, I will introduce our numerical strategies for systematically building low-energy models with local charge, spin, and orbital degrees of freedom of arbitrary complexity. I will discuss the insights that these methods have yielded for frustrated magnetic insulators collectively known as "Kitaev materials", which have prompted a recent explosion of interest in quantum magnets where spin-orbit coupling induces strongly anisotropic and competing magnetic interactions. I will specifically address our recent attempts to understand the magnetic models of few-layer RuCl3 and high-spin d7 Co(II) compounds, which have recently been identified as possible alternative platforms for realising the celebrated Kitaev model.
