Single quantum dots as artificial atoms, quantum optics and quantum cryptography at the Tyndall National Institute.
The Tyndall National Institute hosts a number of prominent experimental activities in the field of quantum information technologies. Two groups are active. The first one, led by Paul Townsend, is widely-recognised as one of the founders of the field of experimental Quantum Key Distribution (QKD), being the first to demonstrate phase-encoded QKD in fibre links and multi-user and multi-wavelength networks whilst at BT Labs in the UK. At Tyndall, his group have demonstrated the potential for “quantum information to the home” by using novel cross talk mitigation techniques to enable the co-existence of QKD and high power classical data channels in fibre-to the-home networks. The second, led by E. Pelucchi, is the only experimental team in Ireland which (at the moment) routinely performs cryogenic quantum optics experiments. The group has developed a full technology thread in house, starting from the epitaxy of single site-controlled quantum dots, their “quantum” characterization as, e.g., entangled photon emitters, to the development of single electrically pumped devices, which, as recently reported, allow Bell's inequalities violation.
