Rev.  ...  We then construct a universal set of fault-tolerant gates without state distillation by using only transversal controlled-controlled-Z, transversal Hadamard, and fault-tolerant error correction.  ...  For H to be transversal, the code must be self-dual, i.e., G 0 ¼ G ? . Unfortunately, no triorthogonal code is self-dual.  ...

Sparse Quantum Codes from Quantum Circuits

2015 Proceedings of the Forty-Seventh Annual ACM on Symposium on Theory of Computing - STOC '15  
Previously the best code distance achievable with constant-weight generators in any dimension, due to Freedman, Meyer and Luo, was O(√(n n)) for a stabilizer code.  ...  Applying our construction to certain concatenated stabilizer codes yields families of subsystem codes with constant-weight generators and with minimum distance d = n^1-ϵ, where ϵ = O(1/√( n)).  ...  DB was supported by the NSF under Grants No. 0803478, 0829937, and 0916400 and by the DARPA-MTO QuEST program through a grant from AFOSR.  ...

Fault-Tolerant Conversion between the Steane and Reed-Muller Quantum Codes

Jonas T. Anderson, Guillaume Duclos-Cianci, David Poulin
2014 Physical Review Letters  
The 15-qubit Reed-Muller code also does not admit a universal fault-tolerant gate set but possesses fault-tolerant T and control-control-Z gates.  ...  Steane's 7-qubit quantum error-correcting code admits a set of fault-tolerant gates that generate the Clifford group, which in itself is not universal for quantum computation.  ...  Elements of A z m are obtained in a similar way, but from the generator matrix of the shortened dual code RMðm − 2; mÞ. In a CSS code, A x detects z-type errors and A z detects x-type errors.  ...
