Phantom Codes: Hardness, Rate Optimal qLDPC Constructions, and Distance Limits
Rui Mao, Weixiao Sun, Shengyu Zhang
An stabilizer code is phantom if every in-block logical CNOT gate can be realized by a permutation of its physical qubits. This eliminates the large and complicated phy…

The sudden death of quantum advantage in correlation generations
Weixiao Sun, Fuchuan Wei, Yuguo Shao +1
As quantum error corrections still cannot be realized physically, quantum noise is the most profound obstacle to the implementations of large-scale quantum algorithms or quantum sc…

Equivalence checking of quantum circuits by nonlocality
Weixiao Sun, Zhaohui Wei
Suppose two quantum circuit chips are located at different places, for which we do not have any prior knowledge, and cannot see the internal structures either. If we want to find o…
