High-Probability Heralded Entanglement via Repeated Spin-Photon Phase Encoding with Moderate Cooperativity
Yu Liu, Martin B. Plenio
We propose a heralded high-probability scheme to generate remote entanglement between moderate-cooperativity spin-cavity registers with high fidelity. In conventional single-shot i…
Resource state generation for a multispin register in a hybrid matter-photon quantum information processor
Yu Liu, Martin B. Plenio
Hybrid quantum architectures that integrate matter and photonic degrees of freedom present a promising pathway toward scalable, fault-tolerant quantum computing. This approach need…
Overcoming frequency resolution limits using a solid-state spin quantum sensor
Qingyun Cao, Genko T. Genov, Yaoming Chu +4
The ability to determine precisely the separation of two frequencies is fundamental to spectroscopy, yet the resolution limit poses a critical challenge: distinguishing two incoher…
Analysis of Parameterized Quantum Circuits: on The Connection Between Expressibility and Types of Quantum Gates
Yu Liu, Kentaro Baba, Kazuya Kaneko +3
Expressibility is a crucial factor of a Parameterized Quantum Circuit (PQC). In the context of Variational Quantum Algorithms (VQA) based Quantum Machine Learning (QML), a QML mode…
