Quantum-classical crossover in fault-tolerant quantum dynamics simulation
Jinzhao Sun, Bozhen Zhou, Jue Xu +28
While quantum computers promise to solve classically intractable problems, identifying the point at which fault-tolerant quantum computation outperforms the best classical algorith…
Quantum probe advantage in learning many-body systems
Wenzheng Dong, Andrew G. Green, Vlatko Vedral +1
Which properties of a quantum many-body system are operationally accessible is a central question underlying spectroscopy, thermodynamics, and quantum information science. Conventi…
Efficient learning and optimizing non-Gaussian correlated noise in digitally controlled qubit systems
Wenzheng Dong, Yuanlong Wang, Muhammad Qasim Khan
Precise qubit control in the presence of spatio-temporally correlated noise is pivotal for transitioning to fault-tolerant quantum computing. Generically, such noise can also have…
SPAM-Robust Multi-axis Quantum Noise Spectroscopy in Temporally Correlated Environments
Muhammad Qasim Khan, Wenzheng Dong, Leigh M. Norris +1
Characterizing temporally correlated (``non-Markovian'') noise is a key prerequisite for achieving noise-tailored error mitigation and optimal device performance. Quantum noise spe…
