Efficient Inner-product Algorithm for Stabilizer States

Garcia, Hector J., Markov, Igor L., Cross, Andrew W.

Understand

Large-scale quantum computation is likely to require massive quantum error correction (QEC).

  • QEC codes and circuits are described via the stabilizer formalism, which represents stabilizer states by keeping track of the operators that preserve them.
  • Such states are obtained by stabilizer circuits (consisting of CNOT, Hadamard and Phase only) and can be represented compactly on conventional computers using Omega(n^2) bits, where n is the number of qubits.
  • Although techniques for the efficient simulation of stabilizer circuits have been studied extensively, techniques for efficient manipulation of stabilizer states are not currently available.
