    "abstract": "Coulomb blockade effects in capacitively coupled quantum dots can be utilized\nfor constructing an N-qubit system with antiferromagnetic Ising interactions.\nStarting from the tunneling Hamiltonian, we theoretically show that the\nHamiltonian for a weakly coupled quantum-dot array is reduced to that for\nnuclear magnetic resonance (NMR) spectroscopy. Quantum operations are carried\nout by applying only electrical pulse sequences. Thus various error-correction\nmethods developed in NMR spectroscopy and NMR quantum computers are applicable\nwithout using magnetic fields. A possible measurement scheme in an N-qubit\nsystem is quantitatively discussed.",
