QUBO formulations for training machine learning models
Scientific Reports, 2021 Training machine learning models on classical computers is usually a time and compute intensive process. With Moore’s law nearing its inevitable end and an ever-increasing demand for large-scale data analysis using machine learning, we must leverage non ...

Radical TADF: Quartet‐Derived Luminescence with Dark TEMPO
Advanced Materials, EarlyView.A new class of luminescent organic quantum materials is introduced, formed by attaching a stable radical to TADF chromophores. Due to ferromagnetic exchange coupling, a high‐spin quartet state forms upon excitation, which can thermally access a bright state.

Adiabatic Theorems and Reversible Isothermal Processes [PDF]
Letters in Mathematical Physics, 2005 Isothermal processes of a finitely extended, driven quantum system in contact with an infinite heat bath are studied from the point of view of quantum statistical mechanics. Notions like heat flux, work and entropy are defined for trajectories of states close to, but distinct from states of joint thermal equilibrium. A theorem characterizing reversible

Adiabatic Passage through Chaos. [PDF]
Physical Review Letters, 2018 We study the process of nonlinear stimulated Raman adiabatic passage within a classical mean-field framework. Depending on the sign of interaction, the breakdown of adiabaticity in the interacting nonintegrable system is not related to bifurcations in ...

Efficient analysis of stochastic gene dynamics in the non-adiabatic regime using piecewise deterministic Markov processes [PDF]
Journal of the Royal Society Interface, 2017 Single-cell experiments show that gene expression is stochastic and bursty, a feature that can emerge from slow switching between promoter states with different activities.

Monolithic Terahertz Topological Mach‐Zehnder Interferometer
Advanced Materials, EarlyView.A monolithic topological Mach‐Zehnder interferometer (MZI) is presented, integrating the splitter, combiner, and waveguide arms on a single chip. The interferometric fringes exhibiting high on‐off contrast with extinction ratios over 20 dB are achieved by utilizing tailored unit cells that facilitate interface‐dependent out‐of‐plane radiation losses ...
