"avoids problematic complexity... implements algorithm quantum interactions... natural rather than induced entanglement... fewer connections among qubits reduces decoherence impact... single quantum spin using 2 qubits interact rest of qubits, then single magnetic pulse acts only on central spin implements most complex part of quantum Grover's algorithm... time-dependent external magnetic field pulses rotate spins... few precision errors in control fields & other physical parameters, no need for quantum error correction"
