Stabilizer Slicing is published in Physical Review Letters

December 18, 2018

Our manuscript "Stabilizer Slicing: Coherent error cancellations in low-density parity-check codes" has been published in Physical Review Letters and can be found here. This work describes a method to cancel out coherent overrotation errors that are applied during quantum error correction. 

 

(Top) Circuit schematic for stabilizer slicing. When implemented on a clean codestate, the overrotations (red), interfere destructively.

(Bottom) Logical error rates for Surface-17, comparing a standard implementation to one which is stabilizer sliced. In this plot two and three-qubit gate infidelities are 0.001.
