Parallel-Electromagnetically-Induced-Transparency Near Ground-State Cooling of a Trapped-ion Crystal
Jie Zhang, Man-Chao Zhang, Yi Xie +8
We theoretically propose and experimentally demonstrate a parallel-electromagnetically-induced transparency (parallel-EIT) cooling technique for ion crystals in the Paul trap. It h…
Noise-Resistant Quantum State Compression Readout
Chen Ding, Xiao-Yue Xu, Yun-Fei Niu +2
Qubit measurement is generally the most error-prone operation that degrades the performance of near-term quantum devices, and the exponential decay of readout fidelity severely imp…
Strong quantum computational advantage using a superconducting quantum processor
Yulin Wu, Wan-Su Bao, Sirui Cao +51
Scaling up to a large number of qubits with high-precision control is essential in the demonstrations of quantum computational advantage to exponentially outpace the classical hard…
Steady state phonon occupation of EIT cooling: higher order calculations
Shuo Zhang, Tian-Ci Tian, Zheng-Yang Wu +5
Electromagnetically induced transparency (EIT) cooling has established itself as one of the most widely used cooling schemes for trapped ions during the past twenty years. Compared…
Sending or not sending twin-field quantum key distribution with distinguishable decoy states
Yi-Fei Lu, Mu-Sheng Jiang, Yang Wang +5
Twin-field quantum key distribution (TF-QKD) and its variants can overcome the fundamental rate-distance limit of QKD which has been demonstrated in the laboratory and field while…
