High-fidelity, high-scalability two-qubit gate scheme for superconducting qubits

2020 · arXiv (Cornell University)

High-quality two-qubit gate operations are crucial for scalable quantum information processing. Often, the gate fidelity is compromised when the system becomes more integrated. Therefore, a low-error-rate, easy-to-scale two-qubit gate scheme is highly desirable. Here, we …

Suppressing Coherent Two-Qubit Errors via Dynamical Decoupling

2021 · Physical Review Applied

Scalable quantum information processing requires the ability to tune multiqubit interactions. This makes the precise manipulation of quantum states particularly difficult for multiqubit interactions because tunability unavoidably introduces sensitivity to fluctuations in the tuning parameters, …
