1301.4796 (Tetsufumi Tanamoto et al.)

Strategy for implementing stabilizer-based codes on solid-state qubits    [PDF]

Tetsufumi Tanamoto, Vladimir M. Stojanović, Christoph Bruder, Daniel Becker
We present a method for implementing stabilizer-based codes with encoding schemes of the operator quantum error correction paradigm, e.g., the "standard" five-qubit and CSS codes, on solid-state qubits with Ising or XY-type interactions. Using pulse sequences, we show how to induce the effective dynamics of the stabilizer Hamiltonian, the sum of an appropriate set of stabilizer operators for a given code. Within this approach, the encoded states (ground states of the stabilizer Hamiltonian) can be prepared without measurements and preserved against both the time evolution governed by the original qubit Hamiltonian, and energy-nonconserving errors caused by the environment.
