Execution-transcript privacy for fault-tolerant surface-code memories
Jiachen Shen, Hui Zhong
A fault-tolerant quantum computer runs behind a telemetry stream logging syndromes, decoder actions, resets and timing separately from the answer. Can it reveal the logical input?…
Capability-Gated Conformance Testing of Quantum Error-Correction Decoder Libraries
Jiachen Shen, Hui Zhong
A quantum error correction decoder is a library other people's results depend on, judged in one dominant way. Sample errors, decode, and count wrong logical observables. We ask wha…
The resource cost of magic in a code block
Jiachen Shen, Hui Zhong
We bound the magic of a post-selected logical measurement by the resource that produced it. The setting is one code block with one logical qubit and an adaptive protocol that measu…
UNIQ: Communication-Efficient Distributed Quantum Computing via Unified Nonlinear Integer Programming
Hui Zhong, Jiachen Shen, Lei Fan +4
Distributed quantum computing (DQC) is widely regarded as a promising approach to overcome quantum hardware limitations. A major challenge in DQC lies in reducing the communication…
Differential Privacy Preserving Distributed Quantum Computing
Hui Zhong, Keyi Ju, Jiachen Shen +5
Existing quantum computers can only operate with hundreds of qubits in the Noisy Intermediate-Scale Quantum (NISQ) state, while quantum distributed computing (QDC) is regarded as a…
