Efficient Implementation of a Single-Qutrit Gate Set via Coherent Control
Xiang-Min Yu, Xiang Deng, Wen Zheng +15
Qutrits offer the potential for enhanced quantum computation by exploiting an enlarged Hilbert space. However, the synthesis of high-fidelity and fast qutrit gates, particularly fo…
Information-Scrambling-Enhanced Quantum Sensing Beyond the Standard Quantum Limit
Yangyang Ge, Haoyu Zhou, Wen Zheng +16
Quantum sensing promises measurement precision beyond classical limits, but its practical realization is often hindered by decoherence and the challenges of generating and stabiliz…
Tunable Hybrid-Mode Coupler Enabling Strong Interactions between Transmons at Centimeter-Scale Distance
Jianwen Xu, Xiang Deng, Wen Zheng +12
The transmon, a fabrication-friendly superconducting qubit, remains a leading candidate for scalable quantum computing. Recent advances in tunable couplers have accelerated progres…
Long-Range Interaction via Resonator-Induced Phase in Superconducting Qubits
Xiang Deng, Wen Zheng, Xudong Liao +8
Superconducting quantum computing emerges as one of leading candidates for achieving quantum advantage. However, a prevailing challenge is the coding overhead due to limited quantu…
