We exploit the field gradient created by the diamond atomic sensor, in concert with compressed sensing, to realize imaging protocols, enabling individual nuclei to be located with Angstrom precision.

Jianming Cai, Fedor Jelezko & Martin B. Plenio, Nature Communications 5, Article number: 4065 (2014)

Here we present a proposal for a hybrid device composed of thin film layers of diamond with colour centres and piezoactive elements for the transduction and measurement of physical signals.

Jianming Cai and Martin B. Plenio, Phys. Rev. Lett. 111, 230503(2013)

Here, we show that the essence of the chemical compass model can be understood in analogy to a quantum interferometer exploiting global quantum coherence rather than any subsystem coherence.

We report the detection and polarization of nuclear spins in diamond at room temperature by using a single nitrogen-vacancy (NV) center.

Here we report on the detection of ferritin molecules using magnetic noise induced by the inner paramagnetic iron as a contrast mechanism.

Here, we propose a new solid-state architecture for a scalable quantum simulator that consists of strongly interacting nuclear spins attached to the diamond surface.

Jianming Cai, Phys. Rev. Lett. 106, 100501(2011)

Here, we demonstrate how to optimize the design of a chemical compass with a much better directional sensitivity simply by a gradient field, e.g., from a magnetic nanostructure.

Here, we report an experimental demonstration of every building block of such a model. With four-qubit and six-qubit states, which are not in the cluster-state category, we have realized a universal set of single-qubit rotations, two-qubit entangling gates and also Deutsch's algorithm.

Jianming Cai, Gian Giacomo Guerreschi, and Hans J. Briegel, Phys. Rev. Lett. 104, 220502 (2010)

Here, we show how quantum control can be used to either enhance or reduce the performance of such a chemical compass, providing a new route to further study the radical-pair mechanism and its applications.

J.-M. Cai, W. Dür, M. Van den Nest, A. Miyake, and H. J. Briegel, Phys. Rev. Lett. 103, 050503(2009)

Here, we show that the new resources are universal state preparators after all, and must therefore exhibit a whole class of extremal entanglement features, similar to the cluster states.
