Optimal qudit overlapping tomography and optimal measurement order
Shuowei Ma, Qianfan Wang, Lvzhou Li +1
Quantum state tomography is essential for characterizing quantum systems, but it becomes infeasible for large systems due to exponential resource scaling. Overlapping tomography ad…

The Efficiency Frontier: Classical Shadows versus Direct Quantum Measurement
Shuowei Ma, Junyu Liu
Interfacing quantum and classical processors is an important subroutine in full-stack quantum algorithms. The so-called ``classical shadow'' method efficiently extracts essential c…

Logical qubits with erasure conversion using metastable neutral atoms
Bichen Zhang, Genyue Liu, Guillaume Bornet +6
Implementing large-scale quantum algorithms with practical advantage will require fault-tolerance achieved through quantum error correction, but the associated overhead is prohibit…
