The preparation of thermal equilibrium states is important for the simulation of condensed-matter and cosmology systems using a quantum computer. We present a method to prepare suc…
Appearance of objectivity for NV centers interacting with dynamically polarized nuclear environment
Damian Kwiatkowski, Łukasz Cywiński, Jarosław K. Korbicz
Quantum-to-classical transition still eludes a full understanding. Out of its multiple aspects, one has recently gained an increased attention - the appearance of objective world o…
Full parity phase diagram of a proximitized nanowire island
J. Shen, G. W. Winkler, F. Borsoi +14
We measure the charge periodicity of Coulomb blockade conductance oscillations of a hybrid InSb-Al island as a function of gate voltage and parallel magnetic field. The periodicity…
Conformal Properties of Hyperinvariant Tensor Networks

Single holes confined in semiconductor quantum dots are a promising platform for spin qubit technology, due to the electrical tunability of the -factor of holes. However, the un…
Enhancement of Proximity Induced Superconductivity in a Planar Ge Hole Gas
Kushagra Aggarwal, Andrea Hofmann, Daniel Jirovec +9
Hole gases in planar germanium can have high mobilities in combination with strong spin-orbit interaction and electrically tunable g-factors, and are therefore emerging as a promis…
Roadmap for gallium arsenide spin qubits
Ferdinand Kuemmeth, Hendrik Bluhm
Gate-defined quantum dots in gallium arsenide (GaAs) have been used extensively for pioneering spin qubit devices due to the relative simplicity of fabrication and favourable elect…
Entanglement of dark electron-nuclear spin defects in diamond
M. J. Degen, S. J. H. Loenen, H. P. Bartling +5
A promising approach for multi-qubit quantum registers is to use optically addressable spins to control multiple dark electron-spin defects in the environment. While recent experim…
Optimizing Entanglement Generation and Distribution Using Genetic Algorithms
Francisco Ferreira da Silva, Ariana Torres-Knoop, Tim Coopmans +2
Long-distance quantum communication via entanglement distribution is of great importance for the quantum internet. However, scaling up to such long distances has proved challenging…
Stoquasticity in circuit QED
Alessandro Ciani, Barbara M. Terhal
We analyze whether circuit-QED Hamiltonians are stoquastic focusing on systems of coupled flux qubits: we show that scalable sign-problem free path integral Monte Carlo simulations…
