Title: High fields for Quantum Information Science
Abstract: The vast effort of scaling quantum computers towards eventually hoped-for sizes and fidelities may require an approach based on topology, in order to robustly protect quantum information. I will give an overview of the DOE-funded Quantum Science Center, and its efforts towards fault-tolerant topological quantum computing. I will highlight how high-magnetic field work elucidates the phase diagrams and properties of topological spin liquid candidates such as honeycomb-based Kitaev materials. A prediction is that in the presence of non-Kitaev terms the Kitaev phase will still appear where the ordering is suppressed at high magnetic fields. I will discuss our obtained phase diagrams and physical properties in high magnetic fields and the role of electric polarization in probing symmetry-breaking of magnetic order, disordered phases and phase transitions. To highlight today's practical uses of quantum computers for science, I will briefly talk about Ising chain magnets like Ca3Co2O6. Here we see beautiful agreement between experiments and simulations on D-wave quantum computers. This material's out of equilibrium magnetization vs field steps presents a 30 year puzzle that can now be elucidated with open quantum simulations and compared to experiments in different magnetic field sweep rates.

Title: Magneto-optics, optoelectronics, and optomechanics in 2D materials under a high magnetic field
Abstract: The light-matter interactions can reveal crucial information on quantum material properties, including optically-excited quasiparticles, non-equilibrium carrier dynamics, electron-phonon coupling, and phase transitions. Photons can further manipulate material properties and induce phase transitions. Having full access to optics-based spectroscopy and techniques under a high magnetic field can be challenging due to the restriction of the magnetic bore space, but it is important for material characterization and implementation of quantum sensing. In this talk, I will talk about several works that make use of free-space optical access in magnetic cryostats. I will show how a strong magnetic field can be used to manipulate and study the spin-dependent exciton states in 2D semiconductors through optical spectroscopy, followed by the demonstration of chiral light emitters based on 2D magnetic heterostructures. Finally, I will discuss our investigation of 2D magnetic mechanical resonators and the coupling between spin dynamics and mechanical motion through laser interferometry.

Title: Quantum Limit Lab – with 25T+ superconducting magnets
Abstract: Since its inception, the NHMFL DC-Field Facility has relied on superconducting (SC) magnets to enhance the utility and efficiency of its flagship resistive magnets. These SC magnets also offer an additional advantage by providing a relatively low-noise experimental environment where lower electron temperatures can be achieved, enabling experiments and unlocking new physics insights that would be impractical or impossible with resistive magnet technology. This talk will present a vision for the next phase of the NHMFL: the establishment of the Quantum Limit Lab & a purpose-built, low-noise, high-field laboratory. This facility will house a suite of 25T+ superconducting magnets, leveraging the latest in high-temperature superconductor (HTS) technology developed in collaboration with NHMFL’s Applied Superconductivity Center and an industrial partner. This generational leap in magnetic field strength coupled with a building which will be designed to best exploit these new magnets, will unlock unprecedented experimental capabilities, democratize access to high fields, and serve as a central hub for quantum science initiatives at NHMFL and local academic institutions. The Quantum Limit Lab will enhance the User Program, foster interdisciplinary research, and support education in quantum science and technology. Furthermore, this effort will catalyze the broader application of HTS technology across multiple fields—ranging from quantum science and fusion energy to particle physics experiments—aligned with national priorities and federal funding initiatives.

Title: Multifrequency EPR studies of Lanthanide Coordination Complexes for Quantum Technologies
Abstract: Multifrequency EPR studies allowed us to show that molecular Lanthanide-based coordination complexes hold potential for use as physical supports for the implementation of single- and entangled-qubit quantum gates in Quantum Information Technology devices. [1-4] Multifrequency EPR studies are in particular useful in probing the fundamental mechanisms that induce decoherence in these systems. Furthermore, we investigate the dependence of the phase memory time, Tm, on excitation frequency/resonance field and show that there is an optimum intermediate frequency where Tm is maximized. The above general concepts will be illustrated in the case of Gd(trensal) by magnetic resonance experiments on oriented single-crystals allowing to determine its energy spectrum and study the coherent magnetisation dynamics of its 8S7/2 ground term where the vanishing angular orbital momentum results in decoherence suppression.

Title: Opportunities for non-Abelian anyons in bilayer graphene
Abstract: Even-denominator and other types of unconventional fractional quantum Hall (FQH) states are predicted to host non-Abelian excitations essential for topological quantum computing. Bernal-stacked bilayer graphene (BLG) has emerged to be a promising platform to explore these fundamental phenomena, owing to high sample quality and multi-degrees of freedom. In this talk, I’ll discuss some of the recent progress we made in uncovering the rich physics of the FQH effect in BLG. We observed particle-hole asymmetric even-denominator states on the N=1 Landau level of BLG and accompanying high-order Levin-Halperin states that point to Pfaffian order at some filling factors and anti-Pfaffian at others. We show that the valley isospin in BLG behaves like an SU(2) spin and supports two-component FQH states with controlled valley isospin polarizations. Remarkably, BLG also supports hetero-orbital two-component FQH states at the coincidence of |+0> and |-1> LLs, which were not seen in other 2D systems. Finally I will briefly discuss the work of ours and others in pursuing the fractional charge and exchange statistics in graphene devices, towards the goal of probing and manipulating non-Abelian anyons.

Title: The European Microkelvin Platform: Reflections on user access to the “Lab without Walls”
Abstract: The European Microkelvin Platform (EMP), established in 2014, is a consortium of 17 partners in the academic, technical and industrial sectors with capacity and expertise in ultralow temperature physics. For five years up to 2023 the EU Horizon 2020 infrastructures programme funded training and user access to the facilities of the eight university-based partners, effectively opening up a “laboratory without walls” with distributed capabilities including nanofabrication, quantum device characterisation, sub-mK environments, and high B/T measurement. Doors were opened to both scientific and technological users, and projects ranged from curiosity-driven discovery to the development of practical applications and commercial products. As PI at one of the access-giving sites and Innovation Manager for the EMP consortium I will reflect on progress made, lessons learned and future prospects.
