Quantum computers make use of the principles of quantum superposition and entanglement to solve certain computational problems more efficiently than their classical counterparts.

Our own efforts towards the realization of efficient and scalable schemes for deterministic quantum computation involve:

• Physical implementations of quantum registers with trapped atoms interacting via contact or long-range potentials when excited to high-lying Rydberg states.
• Photonic qubits interacting via the atomic or doped solid-state media.
• Quantum memories with spin-ensembles of atoms or optically active dopants.
• Hybrid quantum systems involving trapped atoms and superconducting circuits.
