Quantum Networking: Towards distributed Quantum computing

Abstract: Quantum Mechanical bits (QUBITS) armed with features of superposition and entanglement offer enormous possibilities in solving some of the most challenging physical problems. The crucial drawback is the loss of coherence times with increasing no of QUBITS. One of the ways to mitigate this issue is by coupling quantum registers coupled via a quantum mechanical link, similar to classical networking of multiple computers/processors. In this talk, I will describe some of the systems that are currently being investigated as ‘Nodes’ and the methods that are being developed for reversible mapping of the internal quantum state of QUBITS to a photon and vice-versa. Emphasis will be on experimental methods in mapping Quantum information between individual atoms and photons.
