Feynman diagrams for possible coherence transfer pathways for a model three-state system, and coordinates for the optimized geometry of GSH; normal mode displacement vectors of the six excited modes ...

The USTC team then enhanced the Zuchongzhi-2 to develop Zuchongzhi-3, featuring 105 qubits and 182 couplers. It achieves a coherence time of 72 microseconds, a single-qubit gate fidelity of 99.90%, a ...

Here, we show that the Bell inequality violation is directly related to the coherence degree, which is controllable by encoding the different local observables into the entangled state. With the usual ...
