Photonic architecture for scalable quantum information processing in NV-diamond
Kae Nemoto, Michael Trupke, Simon J. Devitt +6
Physics and information are intimately connected, and the ultimate information processing devices will be those that harness the principles of quantum mechanics. Many physical syst…
High fidelity gate operations within the coupled nuclear and electron spins of a nitrogen vacancy center in diamond
Mark S. Everitt, Simon Devitt, W. J. Munro +1
In this article we investigate the dynamics of a single negatively charged nitrogen-vacancy center (NV-) coupled to the spin of the nucleus of a 15-nitrogen atom and show that high…
Towards Realizing a Quantum Memory for a Superconducting Qubit: Storage and Retrieval of quantum states
Shiro Saito, Xiaobo Zhu, Robert Amsüss +7
We have built a hybrid system composed of a superconducting flux qubit (the processor) and an ensemble of nitrogen-vacancy centers in diamond (the memory) that can be directly coup…
High-threshold topological quantum error correction against biased noise
Ashley M. Stephens, William J. Munro, Kae Nemoto
Quantum information can be protected from decoherence and other errors, but only if these errors are sufficiently rare. For quantum computation to become a scalable technology, pra…
Quantum communication without the necessity of quantum memories
W. J. Munro, A. M. Stephens, S. J. Devitt +2
Quantum physics is known to allow for completely new ways to create, manipulate and store information. Quantum communication - the ability to transmit quantum information - is a pr…
Classification of Spin-Nematic Squeezing in Spin-1 Collective Atomic Systems
Emi Yukawa, Masahito Ueda, Kae Nemoto
In spin-1 collective atomic systems, the spin and nematic-tensor operators constitute the su(3) Lie algebra whose su(2) subalgebras are shown to give two distinct classes of squeez…
Synthesis of Topological Quantum Circuits
Alexandru Paler, Simon J. Devitt, Kae Nemoto +1
Topological quantum computing has recently proven itself to be a very powerful model when considering large- scale, fully error corrected quantum architectures. In addition to its…
