Distinguished Quantum Colloquium Series: Natural Superlattice Design of Quantum Materials
Time: 10:00 am - 11:00 am
Place: virtual, zoom link at
Speaker: Joseph Checkelsky, MIT
Abstract: Connecting theoretical models for exotic quantum states to real materials is a key goal in quantum materials synthesis. Two-dimensional model systems have been proposed to host a wide variety of exotic phases- historically a number of techniques have been used to realize these including thin film growth and mechanical exfoliation. We describe here our recent progress in experimentally realizing 2D model systems using bulk crystal synthesis including superconducting and topological states. We discuss their structures and the new phenomena that they support. We comment on the perspective for realizing further 2D model systems in complex material structures and their connections to other methods for realizing 2D systems.

IQUIST Seminar: Three routes to topological long-range entanglement in quantum devices: from Hamilton(ians) to Cayley and Galois
Time: 11:00 am - 11:50 am
Place: Please email to request the Zoom link
Speaker: Dr. Ruben Verresen, Harvard University
Abstract: One of the most remarkable discoveries in the last few decades is that collections of entangled qubits can form states of matter whose topological excitations have anyonic exchange statistics. Despite the importance of such states for quantum information purposes, they are extremely challenging to find in materials. In this talk, we explore how novel 'bottom-up' quantum devices---built atom by atom, qubit by qubit---challenge this status quo. Three promising routes are identified for NISQ devices, which this talk will exemplify with experimental data on cold ions and Rydberg tweezer arrays. In particular, long-range entanglement is built through: topological spin liquid ground states, non-equilibrium quantum dynamics, and shallow circuits with measurements and feedforward. Only the latter is able to avoid deep constraints imposed by locality and unitarity, leading to a surprising connection to the unsolvability of the quintic.
