Learn about Quantum devices based on diamond nitrogen-vacancy centers.
Find out how sensors, communication & quantum computing relate.
Defects in diamond crystals which form its colour centres are a very valuable source of quantum systems. The NV centres in diamond possess an electron spin state that can be used as an excellent spin qubit.
These qubits possess some unique features that make this an exciting system to build quantum applications like very long coherence times event at room temperature, facility to access and couple to C13 nuclear spins and finally the ability to couple to photons that can carry quantum information over large distances that can enable quantum networks.
In this webinar, we will address the key advancements in the optimisation of processes for the fabrication of these powerful quantum devices.
Engineering Diamond Devices for Scalable Quantum Networks
Prof. Jason Smith, Oxford University, UK
Many proposed quantum information systems for communications and computing rely on the efficient transfer of information between optical and spin degrees of freedom. Diamond colour centres are excellent candidates for such interfaces, as they can combine highly coherent spin states coupled selectively to coherent optical transitions. Proof-of-concept experiments with nitrogen-vacancy (NV) centres have shown that spins can be entangled over km distances and quantum information stored for over a minute.
In order to advance towards practical devices, two of the principal challenges are the engineering of diamond materials to allow large scale parallelisation, and the engineering of devices to improve the spin-photon coupling efficiency.
In this talk, I will discuss recent efforts directed at both of these challenges, focusing on the controlled writing of colour centres into diamond and the construction of optical microcavity devices to control spontaneous emission.
