Optimal Coherent Quantum Phase Estimation via Tapering
Dhrumil Patel, Shi Jie Samuel Tan, Yigit Subasi +1
Due to its significance as a subroutine, in this work, we consider the coherent version of the quantum phase estimation problem, where given an arbitrary input state and black-box…
Effective Distance of Higher Dimensional HGPs and Weight-Reduced Quantum LDPC Codes
Shi Jie Samuel Tan, Lev Stambler
Quantum error correction plays a prominent role in the realization of quantum computation, and quantum low-density parity-check (qLDPC) codes are believed to be practically useful…
Single-Shot Universality in Quantum LDPC Codes via Code-Switching
Shi Jie Samuel Tan, Yifan Hong, Ting-Chun Lin +2
Code-switching is a powerful technique in quantum error correction that allows one to leverage the complementary strengths of different codes to achieve fault-tolerant universal qu…
Automorphism gadgets in homological product codes
Noah Berthusen, Michael J. Gullans, Yifan Hong +2
The homological product is a general-purpose recipe that forges new quantum codes from arbitrary classical or quantum input codes, often providing enhanced error-correcting propert…
