The robustness of magic state distillation against errors in Clifford gates

Understand

Quantum error correction and fault-tolerance have provided the possibility for large scale quantum computations without a detrimental loss of quantum information.

• A very natural class of gates for fault-tolerant quantum computation is the Clifford gate set and as such their usefulness for universal quantum computation is of great interest.
• Clifford group gates augmented by magic state preparation give the possibility of simulating universal quantum computation.
• However, experimentally one cannot expect to perfectly prepare magic states.
