Creating and manipulating quantum decoherence-free, or noiseless, systems of qudits

(Session 10 : Saturday from 3:30-4:00)

Abstract. Qudits are promising candidates for many quantum information processing tasks. They can be more entangled than qubits, can share a larger fraction of the entanglement in some cases, and may be required for some quantum information processing tasks. I will show how to make entangled qutrit states using photons which form a decoherence-free subspace and show how, in principle, we can manipulate qudit decoherence-free subspaces comprised of quDits.
