One More Time: Revisiting Neural Quantum States from a Reinforcement Learning Perspective

Kavli Affiliate: Eliska Greplova | Summary:Neural quantum states (NQS) provide a flexible and scalable framework for approximating quantum many-body wavefunctions. Among NQS parameterizations, autoregressive models are especially attractive because they enable exact, independent sampling from the Born distribution, avoiding the autocorrelation and mixing issues of Markov chain methods. Yet their optimization remains comparatively underexplored: Adam […]

A unified framework for determining transition dipole polarization in solid-state spin defects

Kavli Affiliate: Simon Groblacher | Summary:Spin-photon interfaces based on solid-state defects are key building blocks for scalable quantum networks and hybrid quantum platforms. Optimizing light-matter coupling in these systems requires precise knowledge of the optical transition dipole polarization, yet for many promising quantum emitters this quantity is hard to determine and therefore remains poorly characterized. […]

Optimizing Resource Costs: A Practical Guide to Achieving Target Security in Verifiable Blind Quantum Computing

Kavli Affiliate: Stephanie Wehner | Summary:Verifiable blind quantum computing (VBQC) enables a resource-limited client to securely delegate computations to an untrusted quantum server while maintaining privacy and detecting deviations from the prescribed computation. The noise-robust VBQC protocol of Leichtle et al. achieves this through a round-based structure: the client delegates multiple computation rounds and test […]

Spin qubit operations by conveyor-mode shuttling

Kavli Affiliate: Lieven Vandersypen | Summary:Dynamic qubit routing is emerging as a promising architectural path for semiconductor quantum processors. Charge carriers can be rapidly moved around on a chip using traveling-wave potentials known as conveyors, preserving the spin state with high fidelity. Originally developed for spin transport, conveyor-mode shuttling may also offer opportunities for performing […]

Experimental Characterization and Modeling of Measurement-Induced State-Transitions in a Fluxonium Superconducting Qubit

Kavli Affiliate: Christian Andersen | Summary: Superconducting qubits are most often measured using dispersive readout, which, ideally, implements a projective quantum non-demolition (QND) measurement. While a larger readout drive can increase the signal and, thus, reduce discrimination errors in the readout, strong microwave drives may also cause non-QND errors by driving the qubit to a […]

High-fidelity two-qubit gates in a 7-qubit register for quantum networks

Kavli Affiliate: Tim H. Taminiau | Summary:Quantum networks based on optically active solid-state spins may enable quantum technologies including long-range quantum communication and distributed quantum computing. Network nodes containing multiple high-fidelity qubits can facilitate large-scale fault-tolerant operation. However, the stringent error thresholds remain out of reach for multi-qubit registers. In this work, we demonstrate high-fidelity […]

Tunable supramolecular polymerization from protein charge heterogeneity and architecture

Kavli Affiliate: Liedewij Laan | Summary:Multidomain proteins with flexible unstructured sequence regions are abundant in cellular signaling. This protein architecture enables self-assembly into supramolecular structures, but how structured interaction domains and overall protein architecture jointly regulate the assembly size, structure and kinetics remains unclear. Here we use the budding yeast protein Bem1 as a model […]

Examining the Challenges of Intellectual Property in AI-Generated Productions

Kavli Affiliate: Mazhar Ali | Summary: With the advancement of artificial intelligence systems capable of autonomously generating artistic, literary, musical works, and even inventions without direct human intervention, the intellectual property (IP) regime faces unprecedented questions and challenges. The most critical issue concerns the ownership of moral and economic rights in the absence of a […]
