Constant-depth global shadow estimation
Qingyue Zhang, Zhou You, Dayue Qin +3
Reliable and scalable readout strategies are essential for quantum technologies. As quantum processors grow, extracting useful information must remain feasible without measurement…
Ultra-Precise Quantum Projective Designs in Constant Depth
Qingyue Zhang, Junjie Chen, Zhou You +1
Random quantum objects are powerful resources for quantum information processing, yet exact Haar randomness is costly and typically unnecessary. We introduce an explicit sparse com…
First mass determination of electroweak vortex rings in the Standard Model
Dan Zhu, Qingyue Zhang, Khai-Ming Wong +1
We report the first rigorous evaluation of the physical mass of electroweak vortex rings, establishing precise values of 18.01 and 26.80 TeV for solutions characterized by differen…
Phase shadow: A noise-tolerant path to global quantum property estimation
Qingyue Zhang, Dayue Qin, Zhou You +3
Measuring global quantum properties-such as the fidelity to complex multipartite states-is both an essential and experimentally challenging task. Classical shadow estimation offers…
Minimal Clifford Shadow Estimation by Mutually Unbiased Bases
Qingyue Zhang, Qing Liu, You Zhou
Predicting properties of large-scale quantum systems is crucial for the development of quantum science and technology. Shadow estimation is an efficient method for this task based…
