Simulating the Charge-Resonance Check in Nitrogen-Vacancy Centers using Python

In this report we present a model to simulate the performance and robustness of the Charge-Resonance Check (CR-Check) in the Nitrogen-Vacancy (NV) center. The CR-Check is a routine which verifies that the charge state of the NV center is NV$^-$ and that the lasers, addressing the NV center, are on resonance with the optical lines. This is done...

Quantum Enhanced Accelerometer using NV Centres in Diamond

Silicon accelerometers used in the automotive industry should be improved in resolution and accuracy. Exploiting quantum effects in diamond to improve sensing accuracy is a popular technique for nanoscale sensing applications. This thesis will present a new design concept for an accelerometer using these quantum effects for sensing on a...

Parameter Estimation of the Hamiltonian of the Nitrogen-Vacancy Center in Diamond

The Hamiltonian of the NV center contains unknown parameters, such as the zero-field splitting and the magnetic field. Knowing how the frequency measurements depend on the parameters will give greater understanding<br/>of the NV center. Including the nitrogen nuclear spin gives us the opportunity to find more parameters such as the quadrupole...

Distributed quantum memory using NV centers

There are still great hurdles to overcome in the construction of a practical quantum computer. Most significantly, there is still great need for less noisy operation devices and the ability to scale the computer into hundreds or thousands of qubits. In this work we study a approach to construct a practical quantum computer which is fundamentally...

Homogeneous broadening of the zero-phonon line in the nitrogen-vacancy centre in diamond for all strain regimes

The nitrogen-vacancy centre in diamond has shown to be a promising solid-state spin-qubit for applications in quantum information processing. NV centres can be used as nodes in quantum communication networks by remote controlled entanglement. The success of such entanglement schemes depends on the probability of photons being emitted in the zero...

Control, measurement and entanglement of remote quantum spin registers in diamond

A quantum network is the essential resource for distributed quantum computation and the enabling technology for secure quantum communication over large distances. Setting up such a network would require establishing quantum connections between local nodes which are capable of generating, processing and storing quantum information. Intensive...
