Fidelity as a figure of merit in quantum error correction
... orthogonal to the 12 previous vectors. Hence, these 32 vectors, called syndrome vectors, will form an orthonormal basis in the 25 = 32-dimensional Hilbert code space. We will use the notation |Sjkl i, where the index j denotes the logical qubit (0 or 1), 1 ≤ k ≤ 5 indicates which qubit is erroneous, ...

On Stability of Equilibrium Solutions in the Restricted Many
... ijklmn are to be found from the condition that the fourth-order term H4 takes the simplest form (note that this term can not be cancelled). In the case of absence of resonances up to the fourth order the Hamiltonian is reduced to the form H0 = Σ1 r1 - Σ2 r2 + Σ3 r3 + c11 r1 2 + c12 r1 r2 + c13 r1 r3 ...
