Colour Centre Formation in Silicon-On-Insulator for On-Chip Photonic Integration Colour centres in silicon have great potential as single photon sources for quantum technologies. Some of them - like the T centre - also possess optically-active spins that enable spin-photon interfa...

A key focus of our photonic pilot line in 2025 was developing capabilities to form and control colour centers in silicon: our quantum emitters! Our project exploring ex-situ generation methods delivered very fruitful results, now wrapped up in a paper just published online: arxiv.org/abs/2601.17919

Don't miss Gabriela Oliveira's first PhD paper (supervised by Nina Glaser): "Quantum block Krylov subspace projector algorithm for computing low-lying eigenenergies," now published in Physical Review A.

Effective equilibrium theory of quantum light-matter interaction in cavities for extended systems and the long wavelength approximation - Communications Physics The hybrid behavior of strongly interacting light and matter in cavities can be engineered by tailoring the cavity parameters, but simulating such systems is hard due to the complexity of the matter…

A recent publication by Mark Kamper and colleagues that delves into formulating an effective, non-perturbative approach for low-dimensional crystals situated within a Fabry-Perot cavity.

A Monte Carlo approach to bound Trotter error Trotter product formulas are a natural and powerful approach to perform quantum simulation. However, the error analysis of product formulas is challenging, and their cost is often overestimated. It is...

In a new paper today with @aleksei-quantum.bsky.social and @abaysmidt.bsky.social, we demonstrate a practical numerical approach to provide tight bounds on Trotter error.

Hello world! NQCP is on BlueSky - who are we? We're building a fault-tolerant quantum computer at the Niels Bohr Institute, and that's going to take a while, so keep up with us here for scientific publications and other updates.
