Coherent manipulation of a tunable hybrid qubit via microwave control

2023 · Chinese Physics B

Hybrid qubits enable the hybridization of charge and spin degrees of freedom, which provides a way to realize both a relatively long coherence time and rapid qubit manipulation. Here, we use microwave driving to demonstrate …

Can Variational Quantum Algorithms Demonstrate Quantum Advantages? Time Really Matters

2023 · arXiv (Cornell University)

Applying low-depth quantum neural networks (QNNs), variational quantum algorithms (VQAs) are both promising and challenging in the noisy intermediate-scale quantum (NISQ) era: Despite its remarkable progress, criticisms on the efficiency and feasibility issues never stopped. …

Certification of genuinely entangled subspaces of the five qubit code via robust self-testing

2025 · Reports on Progress in Physics

Self-testing provides a device-independent framework for certifying quantum properties based solely on input-output statistics while treating quantum devices as black boxes. It has evolved significantly from its origins in bipartite systems to applications in multipartite …
