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 …

Noncyclic nonadiabatic geometric quantum gates in a superconducting circuit

2023 · Physical Review Applied

Quantum gates based on geometric phases possess intrinsic noise-resilience features and attract much attention. However, the implementations of previous geometric quantum computation typically require a long pulse time of gates. As a result, their experimental …
