Dressed-state relaxation in coupled qubits as a source of two-qubit gate errors
Ruixia Wang, Jiayu Ding, Chenlu Wang +8
Understanding error mechanisms in two-qubit gate operations is essential for building high-fidelity quantum processors. While prior studies predominantly treat dephasing noise as e…
Efficient Implementation of Arbitrary Two-Qubit Gates via Unified Control
Zhen Chen, Weiyang Liu, Yanjun Ma +16
The native gate set is fundamental to the performance of quantum devices, as it governs the accuracy of basic quantum operations and dictates the complexity of implementing quantum…
Suppressing spurious transitions using spectrally balanced pulse
Ruixia Wang, Yaqing Feng, Yujia Zhang +10
Achieving precise control over quantum systems presents a significant challenge, especially in many-body setups, where residual couplings and unintended transitions undermine the a…
Exact Decoding of Repetition Code under Circuit Level Noise
Hanyan Cao, Shoukuan Zhao, Dongyang Feng +8
Repetition code forms a fundamental basis for quantum error correction experiments. To date, it stands as the sole code that has achieved large distances and extremely low error ra…
