Single-Shot Readout of a Single Nuclear Spin
Philipp Neumann,J. Beck,Matthias Steiner,F. Rempp,Helmut Fedder,Philip R. Hemmer,Jörg Wrachtrup,Fedor Jelezko +7 more
TL;DR: Single-shot, projective measurement of a single nuclear spin in diamond is demonstrated using a quantum nondemolition measurement scheme, which allows real-time observation of an individual nuclear spin’s state in a room-temperature solid.

Quantum register based on coupled electron spins in a room-temperature solid.
Philipp Neumann,Roman Kolesov,Boris Naydenov,J. Beck,F. Rempp,Matthias Steiner,Vincent Jacques,Gopalakrishnan Balasubramanian,Matthew Markham,Daniel J. Twitchen,S. Pezzagna,Jan Meijer,Jason Twamley,Fedor Jelezko,Jörg Wrachtrup +14 more
TL;DR: In this article, coherent coupling between two electron spins separated by almost 10 nm has been demonstrated, which might enable the construction of a network of connected quantum registers at room temperature, at this distance, the spins can be addressed individually.
Single ion coupled to an optical fiber cavity.
TL;DR: Owing to the small mode volume of the fiber resonator, the coherent coupling strength between the ion and a single photon exceeds the natural decay rate of the dipole moment and is a step towards cavity quantum electrodynamics based quantum information processing with trapped ions.

Dark States of Single Nitrogen-Vacancy Centers in Diamond Unraveled by Single Shot NMR
G. Waldherr,J. Beck,Matthias Steiner,Philipp Neumann,Adam Gali,Th. Frauenheim,Fedor Jelezko,Jörg Wrachtrup +7 more
TL;DR: In this article, the nitrogen-vacancy (NV) center in diamond is shown to exist in an equilibrium of two charge states, i.e., 70% in the expected negative and 30% in neutral states.

Enhanced generation of single optically active spins in diamond by ion implantation.
Boris Naydenov,V. Richter,J. Beck,Matthias Steiner,Philipp Neumann,Gopalakrishnan Balasubramanian,Jocelyn Achard,Fedor Jelezko,Jörg Wrachtrup,Rafi Kalish +9 more
TL;DR: In this article, a two-step implantation process which includes low dose N2+ molecular ion implantations followed by high dose C implantation can increase the generation efficiency of nitrogen-vacancy (NV) centers by over 50%.
