Quantum computers try to utilise novel features of quantum mechanics to increase the computational power of computers. Features such as superposition and entanglement are expected to enable quantum computers to tackle complex problems that no classical computer can solve in a reasonable time. However, the realisation of sufficiently large computers is extremely difficult. Developing suitable quantum systems to act as qubits and quantum gates are challenging tasks. Furthermore, we will have to deal with problems such as decoherence and noise. Dr N. Shaji's field of interest is quantum information theory, weak measurements, controlling decoherence etc. His group also has experience in quantum simulations using IBM quantum computers. The group actively participate in the Special Interest Group on Quantum Computing and Information Science, CUSAT.
