Bell scenarios with communication

open access: yes, 2016
Classical and quantum physics provide fundamentally different predictions about experiments with separate observers that do not communicate, a phenomenon known as quantum nonlocality.

Photochemical Conversion of Indazoles into Benzimidazoles

open access: yesAngewandte Chemie International Edition, Accepted Article.
Fragment‐based drug discovery relies on preparing diverse libraries of advanced building blocks, often incorporating heteroaromatic motifs. Altering the core of heteroaromatics to maximise library diversity typically requires de novo synthesis of each system. This can be often challenging when specific substitution patterns are needed.

Isoselenourea‐Catalyzed Enantioselective Pyrazolo‐heterocycle Synthesis Enabled By Self‐correcting Amide and Ester Acylation

open access: yesAngewandte Chemie International Edition, Accepted Article.
Pyrazole heterocycles are prevalent in a wide range of medicinal and agrochemical compounds and as such the development of methods for their enantioselective incorporation into molecular scaffolds is highly desirable. This manuscript describes the effective formation of fused pyrazolo‐pyridones and ‐pyranones in high enantioselectivity (up to >99:1 er)

Fermionic Linear Optics Revisited

open access: yes, 2004
We provide an alternative view of the efficient classical simulatibility of fermionic linear optics in terms of Slater determinants. We investigate the generic effects of two-mode measurements on the Slater number of fermionic states.

Luminescent Lanthanide Complexes with Fluorinated Heterocycles as Light‐Harvesting Antennae

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The luminescence of trivalent lanthanide (Tb, Eu, Sm, Dy) coordination compounds was optimized. The electronic properties of the light‐harvesting antenna were modulated by regioselective fluorination and trifluoromethylation. The effects of the coordination geometry of the metal ion and the linker connecting the carbostyril and the metal‐binding site ...

Precision Activity‐Based α‐Amylase Probes for Dissection and Annotation of Linear and Branched‐Chain Starch‐Degrading Enzymes

open access: yesAngewandte Chemie, Volume 137, Issue 5, January 27, 2025.
Activity‐based probes were designed as a method to annotate substrate specificity of retaining α‐amylases. Fluorescent probes were used in activity‐based protein profiling experiments with pure protein, a prominent gut microbe and in a species‐rich composter sample.

Topological Wilson-loop area law manifested using a superposition of loops

open access: yes, 2013
We introduce a new topological effect involving interference of two meson loops, manifesting a path-independent topological area dependence. The effect also draws a connection between quark confinement, Wilson-loops and topological interference effects ...

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

What can we Learn from Quantum Convolutional Neural Networks?

open access: yesAdvanced Quantum Technologies, EarlyView.
Quantum Convolutional Neural Networks have been long touted as one of the premium architectures for quantum machine learning (QML). But what exactly makes them so successful for tasks involving quantum data? This study unlocks some of these mysteries; particularly highlighting how quantum data embedding provides a basis for superior performance in ...
