Exploring quantum spin models with Rydberg atom arrays

IQOQI Quantum Seminar

Speaker: Daniel Barredo
When: Feb. 8 2023 09:00
Where: Erwin Schrödinger Saal

Rydberg atoms in arrays of optical tweezers offer a new perspective for the quantum simulation of many body problems. In this seminar, I will give a brief overview about this platform and describe our efforts to control Rydberg interactions to explore different types of Hamiltonians. I will report on our recent implementation of the 2D Ising Hamiltonian [1] and the dipolar XY model [2] with more than 100 spins to study quantum magnetism. I will show our first steps to scale up the atom numbers in our platform by using a cryogenic environment [3].
