Towards strong coupling between a heavy fluxonium qubit and a phononic crystal membrane resonator – NAJERA SANTOS Baldo Luis
As part of my PhD project, we are aiming to achieve strong electromechanical coupling between a heavy fluxonium superconducting circuit and a phononic crystal membrane resonator. The heavy fluxonium is the perfect candidate to build a quantum electromechanical device with outstanding properties, because its lower energy manifold is in the other of MHz, same as the membrane resonator. Furthermore, the heavy fluxonium is insensitive to charge noise, with a coherence around 100 us, while keeping large charge matrix elements, and it is very non-linear in nature, allowing the coherence manipulation and the creation of non-classical (non gaussian) quantum states of the mechanical membrane resonator, for example, Schrödinger cat states.

Solving the Maximum Independent Set problem with Rydberg atoms – Constantin Dalyac
In the past years, many quantum algorithms have been proposed to tackle hard combinatorial problems which are at the heart of industrial applications. In this talk, we will show in particular that the Maximum Independent Set (MIS) problem, known to be NP-hard, can be naturally encoded in Rydberg atomic arrays. Furthermore, the MIS problem reveals deep connections between many-body physics and complexity theory.
