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…
Spectroscopy and modeling of Yb Rydberg states for high-fidelity two-qubit gates
Michael Peper, Yiyi Li, Daniel Y. Knapp +8
Highly excited Rydberg states and their interactions play an important role in quantum computing and simulation. These properties can be predicted accurately for alkali atoms with…
