The nitrogen-vacancy (NV) colour centre in diamond is an important physical system for
emergent quantum technologies, including quantum metrology, information processing and …

We report on the demonstration of light storage for times greater than a second in praseodymium
doped Y 2 SiO 5 using electromagnetically induced transparency. The long storage …

This paper takes a philosophical look at the Research in Operations Research. First, the
questions" What is Research?" and" What is Operations Research?" are discussed. Next, the …

Informed consent is a central topic in contemporary biomedical ethics. Yet attempts to set
defensible and feasible standards for consenting have led to persistent difficulties. In …

The negatively charged nitrogen-vacancy (NV−) center in diamond has realized new
frontiers in quantum technology. Here, the optical and spin resonances of the NV− center are …

The negatively charged nitrogen-vacancy centre is a unique defect in diamond that possesses
properties highly suited to many applications, including quantum information processing, …

We demonstrate photon echoes in Eu 3+∶ Y 2 SiO 5 by controlling the inhomogeneous
broadening of the Eu 3+ F 0 7↔ D 0 5 optical transition. This transition has a linear Stark shift, …

The optical transition linewidth and emission polarization of single nitrogen-vacancy (NV)
centers are measured from 5 K to room temperature. Interexcited state population relaxation is …

We investigate phonon induced electronic dynamics in the ground and excited states of the
negatively charged silicon-vacancy (${\rm Si}{{{\rm V}}^{-}} $) centre in diamond. Optical …

The negatively charged silicon-vacancy (SiV−) center in diamond is a promising single-photon
source for quantum communications and information processing. However, the center's …
