When Expressivity Is Not Enough: Discrete Routing Geometry in Variational Quantum Circuits
Yu Wang
Finding useful variational quantum circuits requires more than representational capacity: training must also have access to directions that improve the objective. We study how disc…
Early-stage memory effect on the dephasing charger-mediated quantum battery
Yu Wang, Jiasen Jin
We investigate the performance of the charger-mediated quantum battery modeled by a two-qubit system. One of the qubits acts as the battery and the other acts as the charger which…
Two measurement bases are asymptotically informationally complete for any pure state tomography
Tianfeng Feng, Tianqi Xiao, Yu Wang +6
One of the fundamental questions in quantum information theory is to find how many measurement bases are required to obtain the full information of a quantum state. While a minimum…
Quantum Advantage via Efficient Post-processing on Qudit Classical Shadow tomography
Yu Wang
The computation of \(\operatorname{tr}(AB)\) is essential in quantum science and artificial intelligence, yet classical methods for \( d \)-dimensional matrices \( A \) and \( B \)…
Probing critical phenomena in open quantum systems using atom arrays
Fang Fang, Kenneth Wang, Vincent S. Liu +8
At continuous phase transitions, quantum many-body systems exhibit scale-invariance and complex, emergent universal behavior. Most strikingly, at a quantum critical point, correlat…
Quantum Information Scrambling in Quantum Many-body Scarred Systems
Dong Yuan, Shun-Yao Zhang, Yu Wang +2
Quantum many-body scarred systems host special non-thermal eigenstates that support periodic revival dynamics and weakly break the ergodicity. Here, we study the quantum informatio…
