Optimizing quantum error correction through error attribution
Yuguo Shao, Zi-Wen Liu
Logical error rate is a standard benchmark for quantum error correction, providing an aggregate measure of the overall effect of physical noise. In actual QEC architectures, errors…
Can scrambling protect quantum state distinguishability under noise?
Guoding Liu, Chushi Qin, Zitai Xu +2
Quantum state distinguishability is a fundamental concept in quantum information science that underpins a wide range of important practical tasks. Traditionally formulated for pair…
No Universal Purification in Quantum Mechanics
Zhenhuan Liu, Zhenyu Du, Jens Eisert +2
Many central tasks in fundamental physics and quantum information processing are possible only insofar as mixed quantum states can be made purer. In this work, we prove that the li…
Certifying localizable quantum properties with constant sample complexity
Zhenyu Du, Jinchang Liu, Elias X. Huber +2
Characterizing increasingly complex quantum systems is a central task in quantum information science, yet experimental costs often scale prohibitively with system size. Certifying…
Approximate Quantum Error Correction with 1D Log-Depth Circuits
Guoding Liu, Zhenyu Du, Zi-Wen Liu +1
Efficient and high-performance quantum error correction is essential for achieving fault-tolerant quantum computing. Low-depth random circuits offer a promising approach to identif…
Spacetime Quantum Circuit Complexity via Measurements
Zhenyu Du, Zi-Wen Liu, Xiongfeng Ma
Quantum circuit complexity is a fundamental concept whose importance permeates quantum information, computation, many-body physics and high-energy physics. While extensively studie…
Complexity and order in approximate quantum error-correcting codes
Jinmin Yi, Weicheng Ye, Daniel Gottesman +1
We establish rigorous connections between quantum circuit complexity and approximate quantum error correction (AQEC) capability, two properties of fundamental importance to the phy…
Approximate symmetries and quantum error correction
Zi-Wen Liu, Sisi Zhou
Quantum error correction (QEC) is a key concept in quantum computation as well as many areas of physics. There are fundamental tensions between continuous symmetries and QEC. One v…
