Local Universality and Structural Certificates for Minimal Fixed-Depth Two-Qutrit Gate Decomposition
Yurui Liu, Ruoting Dou, Peng Xu +4
We study a dimension-saturating fixed-core ansatz in which four copies of a fixed, non-tunable two-qutrit core are interleaved with five adjustable local layers from $…

Microwave-activated two-qubit gates for fixed-coupling and fixed-frequency transmon qubits
Ling Jiang, Peng Xu, Shengjun Wu +2
All-microwave control of fixed-frequency superconducting quantum systems offers the potential to reduce control circuit complexity and increase system coherence. Nevertheless, due…

High-fidelity gates using a fixed coupler driven by two microwave pulses
Peng Xu, Haitao Zhang, Shengjun Wu
Attaining high-fidelity two-qubit gates represents a pivotal quantum operation for the realization of large-scale quantum computation and simulation. In this study, we propose a mi…
