48. This result is valid for short-range couplings. In the case of long-range couplings where all qubits are coupled, the system is similar to the one studied in Ref. 37, (Formula presented), and we will have (Formula presented), where (Formula presented) is a numerical constant. We note that long-range couplings can appear in systems where collective modes are used in the design of the quantum computer 1112182041.
49. For even n and (Formula presented), the system has an additional symmetry corresponding to the inversion of all (Formula presented) (spin inversion). However, inside one symmetry class the spacing statistics is still close to (Formula presented) according to our numerical data (not shown).
