    "abstract": "We model an isolated quantum computer as a two-dimensional lattice of qubits\n(spin halves) with fluctuations in individual qubit energies and residual\nshort-range inter-qubit couplings. In the limit when fluctuations and couplings\nare small compared to the one-qubit energy spacing, the spectrum has a band\nstructure and we study the quantum computer core (central band) with the\nhighest density of states. Above a critical inter-qubit coupling strength,\nquantum chaos sets in, leading to quantum ergodicity of eigenstates in an\nisolated quantum computer. The onset of chaos results in the interaction\ninduced dynamical thermalization and the occupation numbers well described by\nthe Fermi-Dirac distribution. This thermalization destroys the noninteracting\nqubit structure and sets serious requirements for the quantum computer\noperability.",
