Quantum neural network equipped with backpropagation on a qudit processor
Yibo Yuan, Zhuoyue Xu, Zhenyue Du +7
Quantum neural networks (QNNs), one of the fundamental algorithms in quantum machine learning, have been widely used in classification and identification tasks. However, the capabi…
Experimental observation of parity-symmetry-protected phenomena in the quantum Rabi model with a trapped ion
Xingyu Zhao, Qian Bin, Waner Hou +5
Symmetry is crucial for gaining insights into the fundamental properties of physical systems, bringing possibilities in studying exotic phenomena such as quantum phase transitions…
An energy efficient quantum-enhanced machine
Waner Hou, Xingyu Zhao, Kamran Rehan +5
Quantum friction, a quantum analog of classical friction, reduces the performance of quantum machines, such as heat engines, and makes them less energy efficient. We here report th…
Multi-parameter quantum metrology with stabilized multi-mode squeezed state
Yue Li, Xu Cheng, Lingna Wang +11
Squeezing a quantum state along a specific direction has long been recognized as a crucial technique for enhancing the precision of quantum metrology by reducing parameter uncertai…
