A CS guide to the quantum singular value transformation
Ewin Tang, Kevin Tian
We present a simplified exposition of some pieces of [Gilyén, Su, Low, and Wiebe, STOC'19, arXiv:1806.01838], which introduced a quantum singular value transformation (QSVT) framew…
The Search For Leakage-free Entangling Fibonacci Braiding Gates
Shawn X. Cui, Kevin T. Tian, Jennifer F. Vasquez +2
It is an open question if there are leakage-free entangling Fibonacci braiding gates. We provide evidence to the conjecture for the negative in this paper. We also found a much sim…
Generalized Haah Codes and Fracton Models
Kevin T. Tian, Zhenghan Wang
Entanglement renormalization group flow of the Haah cubic code produces another fracton model with 4 qubits per lattice site, dubbed as the Haah B-code. We provide a schema that ge…
Haah codes on general three manifolds
Kevin T. Tian, Eric Samperton, Zhenghan Wang
Haah codes represent a singularly interesting gapped Hamiltonian schema that has resisted a natural generalization, although recent work shows that the closely related type I fract…
