Two-electron spin correlations in precision placed donors in silicon
Nature Communications, 2018 Donor impurities in silicon are promising candidates as qubits but in order to create a large-scale quantum computer inter-qubit coupling must be introduced by precise positioning of the donors.

Valley interference and spin exchange at the atomic scale in silicon
Nature Communications, 2020 Coupled donor wavefunctions in silicon are spatially resolved to evidence valley interference processes. An atomic-scale understanding of the interplay between interference, envelope anisotropy and crystal symmetries unveils a placement strategy ...

Coordination Games with Quantum Information [PDF]
The paper discusses coordination games with remote players that have access to an entangled quantum state. It shows that the entangled state cannot be used by players for communicating information, but that in certain games it can be used for improving ...

Reconstruction of quantum theory [PDF]
, 2006 What belongs to quantum theory is no more than what is needed for its derivation. Keeping to this maxim, we record a paradigmatic shift in the foundations of quantum mechanics, where the focus has recently from interpreting to reconstructing quantum ...

Engineering Energy Harvesting Pathways in Mn‐Yb‐Doped Perovskite Nanocrystals
Advanced Optical Materials, EarlyView.Mn‐Yb codoping in metal halide perovskite nanocrystals establishes dual‐channel energy reservoirs that capture charge carriers and drip‐feed them back to the host on millisecond timescales. This synergistic recycling mechanism overcomes prompt nanosecond recombination limitations, enabling an eight‐fold enhancement in photocatalytic CO2 reduction ...

Entanglement generation and self-correcting quantum memories [PDF]
, 2012 Building a working quantum computer that is able to perform useful calculations remains a challenge. With this thesis, we are trying to contribute a small piece to this puzzle by addressing three of the many fundamental questions one encounters along the

Modeling Light‐Induced Synaptic Behavior and Visual Memory of Azopolymeric Compounds
Advanced Optical Materials, EarlyView.In the framework of neuromorphic hardware it is essential to predict the evolution of the internal state of the devices mimicking synaptic functionalities to perform in‐silico modeling of specific computational tasks. Here, we provide a rate‐balance equation model to describe the synaptic‐like response of light‐actuated azopolymeric compounds and ...

Advanced Optical Materials, EarlyView.A series of Eu3+, Tb3+, Tm3+ and La3+ formate‐based (mixed)metal‐organic frameworks were synthesized and investigated for energy transfer and white‐light emission. Efficient Tb3+→Eu3+ transfer enabled tuneable luminescence, while Tm3+ incorporation afforded near‐white emission.

MANGO‐“Fruitcage”: A Conditional Photocage Utilizing a Fluorescence Light‐Up Aptamer
Advanced Optical Materials, EarlyView.Fruitcaging ‐ a proof of concept study of a conditional photocage (Thiazol‐Orange) activated upon binding to the fluorescence light up aptamer (Mango). The prolongation of the excited state lifetime explains the redirection of the reactive pathway toward photocleavage and provides a sensitive spectroscopic readout.
