Hamiltonian Decoded Quantum Interferometry for General Pauli Hamiltonians
Kaifeng Bu, Weichen Gu, Xiang Li
In this work, we study the Hamiltonian Decoded Quantum Interferometry (HDQI) for the general Hamiltonians on an -qubit system, where the coefficients $c_i\in \m…

Quantum locally recoverable code with intersecting recovery sets
Kaifeng Bu, Weichen Gu, Xiang Li
We introduce the concept of quantum locally recoverable codes (qLRCs) with intersecting recovery sets. We derive a singleton-like bound for these codes by leveraging the additional…
