Optical coherence of diamond nitrogen-vacancy centers formed by ion implantation and annealing
Suzanne B. van Dam, Michael Walsh, Maarten J. Degen +8
The advancement of quantum optical science and technology with solid-state emitters such as nitrogen-vacancy (NV) centers in diamond critically relies on the coherence of the emitt…
Towards a realization of device-independent quantum key distribution
Gláucia Murta, Suzanne B. van Dam, Jérémy Ribeiro +2
In the implementation of device-independent quantum key distribution we are interested in maximizing the key rate, i.e. the number of key bits that can be obtained per signal, for…
Near-term quantum-repeater experiments with nitrogen-vacancy centers: Overcoming the limitations of direct transmission
Filip Rozpędek, Raja Yehia, Kenneth Goodenough +5
Quantum channels enable the implementation of communication tasks inaccessible to their classical counterparts. The most famous example is the distribution of secret key. However,…
Optimal design of diamond-air microcavities for quantum networks using an analytical approach
Suzanne B. van Dam, Maximilian Ruf, Ronald Hanson
Defect centers in diamond are promising building blocks for quantum networks thanks to a long-lived spin state and bright spin-photon interface. However, their low fraction of emis…
Light, the universe, and everything -- 12 Herculean tasks for quantum cowboys and black diamond skiers
Girish Agarwal, Roland Allen, Iva Bezdekova +29
The Winter Colloquium on the Physics of Quantum Electronics (PQE) has been a seminal force in quantum optics and related areas since 1971. It is rather mindboggling to recognize ho…
Dephasing mechanisms of diamond-based nuclear-spin memories for quantum networks
N. Kalb, P. C. Humphreys, J. J. Slim +1
We probe dephasing mechanisms within a quantum network node consisting of a single nitrogen-vacancy centre electron spin that is hyperfine coupled to surrounding n…
