Observable Estimation in the Absence of Classical Verification

Samantha V. Barron, Bradley Mitchell, Vinay Tripathi +45

The predictive success of quantum mechanics underpins many areas of modern science, even as the exact simulation of large, interacting quantum systems remains beyond the reach of c…

Learning Midcircuit Measurement Backaction from Three Repeated Measurements

Chia-Tung Chu, Su-un Lee, Han Zheng +4

Accurate modeling of midcircuit measurements (MCMs) is essential for dynamic-circuit operations such as syndrome extraction, measurement-based reset, and the separation of state-pr…

Classically Sampling Noisy Quantum Circuits in Quasi-Polynomial Time under Approximate Markovianity

Yifan F. Zhang, Su-un Lee, Liang Jiang +1

While quantum computing can accomplish tasks that are classically intractable, the presence of noise may destroy this advantage in the absence of fault tolerance. In this work, we…

Efficient benchmarking of logical magic state

Su-un Lee, Ming Yuan, Senrui Chen +2

High-fidelity logical magic states are a critical resource for fault-tolerant quantum computation, enabling non-Clifford logical operations through state injection. However, benchm…

Universal Spreading of Conditional Mutual Information in Noisy Random Circuits

Su-un Lee, Changhun Oh, Yat Wong +2

We study the evolution of conditional mutual information in generic open quantum systems, focusing on one-dimensional random circuits with interspersed local noise. Unlike in noise…
