Qubit generation and handling is the heart of any quantum information processing (QIP). Polarisation and angular momentum were most commonly used properties of the photon for production of qubits. Nuclear magnetic resonance(NMR) spectroscopy advanced the experimental technique to realise the QIP. NMR spectroscopy is acknowledged for its richness of diverse coherent manipulations of spin dynamics. Liquid NMR spectroscopy is currently used approach to generate the quantum qubits but the large ratio of the gate time over decoherence time, resetting qubits, non-scalability of pseudo-pure state preparation makes this mode to limit at a low number of usable qubits (currently seven). We present a direction to next generation QIP based on solid state NMR. The central idea of our group is to use few elements in addition to hydrogen-1 for which there is an isotope with no spin, and another with spin ½ (such as carbon-13) nuclei. With the reduced limitation we wish to generate about 10-30 qubits which is a small number regarding quantum computation, the complexity of quantum world can be easily explained using this approach. Quantum Processors (QP) are the most important part of QIP systems. We introduce an idea that shows easiness to manufacturing a QPs to handle the NMR qubits. The next step is to fabricate the large scale QPs which will be able to handle 100 qubits leading us closer to the reality of a future run by truly powerful quantum computers.
