Room-temperature high-speed nuclear-spin quantum memory in diamond
J. H. Shim, I. Niemeyer, J. Zhang +1
Quantum memories provide intermediate storage of quantum information until it is needed for the next step of a quantum algorithm or a quantum communication process. Relevant figure…
Experimental protection of quantum gates against decoherence and control errors
Alexandre M. Souza, Gonzalo A. Álvarez, Dieter Suter
One of the biggest challenges for implementing quantum devices is the requirement to perform accurate quantum gates. The destructive effects of interactions with the environment pr…
Robust Dynamical Decoupling for Arbitrary Quantum States of a Single NV Center in Diamond
J. H. Shim, I. Niemeyer, J. Zhang +1
Dynamical decoupling is a powerful technique for extending the coherence time (T) of qubits. We apply this technique to the electron spin qubit of a single nitrogen-vacancy cen…
Fate of the cluster state on the square lattice in a magnetic field
H. Kalis, D. Klagges, R. Orus +1
The cluster state represents a highly entangled state which is one central object for measurement-based quantum computing. Here we study the robustness of the cluster state on the…
Concatenated dynamical decoupling with virtual pulses
Gonzalo A. Alvarez, Alexandre M. Souza, Dieter Suter
The loss of quantum information due to interaction with external degrees of freedom, which is known as decoherence, remains one of the main obstacles for large-scale implementation…
