Blind Quantum Computation on a Modular Superconducting Processor
Yongxin Song, Johannes Knörzer, Kieran Dalton +2
Current cloud-based quantum processors offer access to advanced hardware hosted on a remote server, but do not guarantee data or algorithm privacy. Blind quantum computation provid…
Color Centers and Hyperbolic Phonon Polaritons in Hexagonal Boron Nitride: A New Platform for Quantum Optics
Jie-Cheng Feng, Johannes Eberle, Sambuddha Chattopadhyay +3
Hyperbolic phonon polaritons (HPPs) in hexagonal boron nitride (hBN) confine mid-infrared light to deep-subwavelength scales and may offer a powerful route to strong light-matter i…
Resource-Efficient Cross-Platform Verification with Modular Superconducting Devices
Kieran Dalton, Johannes Knörzer, Finn Hoehne +7
Large-scale quantum computers are expected to benefit from modular architectures. Validating the capabilities of modular devices requires benchmarking strategies that assess perfor…
Double-bracket quantum algorithms for high-fidelity ground state preparation
Matteo Robbiati, Edoardo Pedicillo, Andrea Pasquale +13
Ground state preparation is a central application for quantum computers but remains challenging in practice. In this work, we quantitatively investigate the performance and gate co…
Cross-Platform Verification in Quantum Networks
Johannes Knörzer, Daniel Malz, J. Ignacio Cirac
Intermediate-scale quantum devices are becoming more reliable, and may soon be harnessed to solve useful computational tasks. At the same time, common classical methods used to ver…
Long-range electron-electron interactions in quantum dot systems and applications in quantum chemistry
Johannes Knörzer, Cornelis J. van Diepen, Tzu-Kan Hsiao +6
Long-range interactions play a key role in several phenomena of quantum physics and chemistry. To study these phenomena, analog quantum simulators provide an appealing alternative…
Wigner Crystals in Two-Dimensional Transition-Metal Dichalcogenides: Spin Physics and Readout
Johannes Knörzer, Martin J. A. Schuetz, Geza Giedke +5
Wigner crystals are prime candidates for the realization of regular electron lattices under minimal requirements on external control and electronics. However, several technical cha…
Solid-state magnetic traps and lattices
Johannes Knörzer, Martin J. A. Schuetz, Geza Giedke +4
We propose and analyze magnetic traps and lattices for electrons in semiconductors. We provide a general theoretical framework and show that thermally stable traps can be generated…
Acoustic Traps and Lattices for Electrons in Semiconductors
Martin J. A. Schuetz, Johannes Knörzer, Geza Giedke +3
We propose and analyze a solid-state platform based on surface acoustic waves (SAWs) for trapping, cooling and controlling (charged) particles, as well as the simulation of quantum…
