Spanning a range of hardware platforms, the building-blocks of quantum processors are
today sufficiently advanced to begin work on scaling-up these systems into complex …

Single electron spins coupled to multiple nuclear spins provide promising multi-qubit
registers for quantum sensing and quantum networks. The obtainable level of control is …

We create and isolate single-photon emitters with a high brightness approaching 10^ 5
counts per second in commercial silicon-on-insulator (SOI) wafers. The emission occurs in …

Even the quantum simulation of an apparently simple molecule such as Fe2S2 requires a
considerable number of qubits of the order of 106, while more complex molecules such as …

Hole spin qubits are frontrunner platforms for scalable quantum computers, but state-of-the-
art devices suffer from noise originating from the hyperfine interactions with nuclear defects …

In recent years, solid-state spin systems have emerged as promising candidates for
quantum information processing. Prominent examples are the nitrogen-vacancy (NV) center …

Single nuclear spins in the solid state are a potential future platform for quantum computing,–
, because they possess long coherence times,–and offer excellent controllability …

We study the use of ensembles of quantum two-level systems as batteries to store and
release radiative energy. Collective coupling to a tuneable cavity mode leads to enhanced …

Single-electron spin qubits employ magnetic fields on the order of 1 Tesla or above to
enable quantum state readout via spin-dependent-tunnelling. This requires demanding …

Nuclear spins with hyperfine coupling to single electron spins are highly valuable quantum
bits. Here we probe and characterize the particularly rich nuclear-spin environment around …
