    Sampling-based quantum advantage schemes currently serve as the leading experimental demonstrations of computational tasks deemed intractable for classical devices. However, their practical significance remains a subject of intense debate as these tasks are synthetically designed to maximize classical hardness rather than to solve meaningful real-world problems. In this contribution, based, we...

    light of emergent evolution in quantum technology, key industrial players allocate significant parts of their budget and resources to identify a real-world problem where quantum advantage, i.e. exponential increase in computational capacity, is expected to appear. The tense competition between quantum computing and simulations on classical hardware over the past decades has been further...

    In this talk, I explain how Faulhorn operates, what our goals are, and how we connect with industry, academia, and research institutes. I will highlight our past projects and spin-off companies, and detail our current work on the Csip, ZKP, MC2P and Qutility projects. Finally, I discuss how AI impacts us, how we are adopting it, and how we aim to create practical value in this new era.

    Point defects are localized irregularities in crystals that break the lattice symmetry of the hosting material. They can potentially be used in quantum technology as a room temperature qubit. Nitrogen-vacancy center (NV center) is the most studied point defect, where in the hosting diamond crystal two adjacent carbon atoms are switched to a nitrogen atom and a vacancy (empty spot).
    The...

    Lecture

    As quantum computing research and teaching continue to grow, so does the material behind each result and each lesson. Reproducing a published implementation depends on having its code, the tools it was built with, and the paper that explains it together, and a single lesson often draws on several tools, from PDFs for the theory and a circuit designer such as IBM Quantum Composer to a...

    Lecture

    Optically addressable electron spins in solids – point defects in diamond, silicon carbide and two-dimensional materials, and molecular spins – are leading platforms for room-temperature quantum sensing. Their development benefits from a close loop between theory and experiment: first-principles simulations on high-performance computers predict structures and spin and optical fingerprints,...

    The strong hyperfine splitting of electronuclear tin-vacancy (SnV) levels in diamond has been shown to allow for optically addressable qubits with long coherence times. In this work we present a model of non-zero nuclear spin SnVs in diamond coupled to a quantised optical mode; the model corresponds to SnVs in photonic crystal cavities or optical cavities made of mirrors, realised in earlier...

    Personalized non-invasive neurostimulation is a candidate tool for closed-loop seizure control. We ask whether a reinforcement learning (RL) agent can learn when and how strongly to stimulate to stop seizure-like activity in a model network. We wrote a network of 100 coupled Morris–Lecar neurons, extended with calcium dynamics, as a TorchRL environment. Each agent step in the environment...

    AI coding agents are becoming part of everyday scientific work. Yet every file, prompt and test output an agent reads may leave the institute. This puts intellectual property at risk, both for new research results that we may want to patent and in joint academic–industry projects. Moreover, contracts or data protection law may forbid passing sensitive data to third parties altogether. As AI...
