Echoed Random Quantum Metrology
Dong-Sheng Liu, Zi-Jie Chen, Ziyue Hua +8
Quantum metrology typically demands the preparation of exotic quantum probe states, such as entangled or squeezed states, to surpass classical limits. However, the need for careful…
Scalable Generation of Macroscopic Fock States Exceeding 10,000 Photons
Ming Li, Weizhou Cai, Ziyue Hua +7
The scalable preparation of bosonic quantum states with macroscopic excitations poses a fundamental challenge in quantum technologies, limited by control complexity and photon-loss…
All-optical control and multiplexed readout of multiple superconducting qubits
Xiaoxuan Pan, Chuanlong Ma, Jia-Qi Wang +12
Superconducting quantum circuits operate at millikelvin temperatures, typically requiring independent microwave cables for each qubit for connecting room-temperature control and re…
Extending coherence time beyond break-even point using only drives and dissipation
Lida Sun, Yifang Xu, Yilong Zhou +11
Quantum error correction (QEC) aims to mitigate the loss of quantum information to the environment, which is a critical requirement for practical quantum computing. Existing QEC im…
