Experimental Quantum End-to-End Learning on a Superconducting Processor
Xiaoxuan Pan, Xi Cao, Weiting Wang +10
Machine learning can be substantially powered by a quantum computer owing to its huge Hilbert space and inherent quantum parallelism. In the pursuit of quantum advantages for machi…
Nearly quantum-limited Josephson-junction Frequency Comb synthesizer
Pinlei Lu, Saeed Khan, Tzu-Chiao Chien +5
While coherently-driven Kerr microcavities have rapidly matured as a platform for frequency comb formation, such microresonators generally possess weak Kerr coefficients; consequen…
End-to-End Quantum Machine Learning Implemented with Controlled Quantum Dynamics
Re-Bing Wu, Xi Cao, Pinchen Xie +1
Toward quantum machine learning deployed on imperfect near-term intermediate-scale quantum (NISQ) processors, the entire physical implementation of should include as less as possib…
Identification of Time-varying in situ Signals in Quantum Circuits
Xi Cao, Yu-xi Liu, Rebing Wu
The identification of time-varying \textit{in situ} signals is crucial for characterizing the dynamics of quantum processes occurring in highly isolated environments. Under certain…
Multiparametric Amplification and Qubit Measurement with a Kerr-free Josephson Ring Modulator
T. -C. Chien, O. Lanes, C. Liu +6
Josephson-junction based parametric amplifiers have become a ubiquitous component in superconducting quantum machines. Although parametric amplifiers regularly achieve near-quantum…
Learning to Calibrate Quantum Control Pulses by Iterative Deconvolution
Xi Cao, Bing Chu, Haijin Ding +3
In experimental control of quantum systems, the precision is often hindered by imperfect applied electronics that distort control pulses delivered to target quantum devices. To mit…
