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…
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…
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…
