- Abstract: Optical quantum technologies promise to revolutionize today's information
processing and sensors. Crucial to many quantum applications are efficient
sources of pure single photons. For a quantum emitter to be used in such
application, or for different quantum systems to be coupled to each other, the
optical emission wavelength of the quantum emitter needs to be tailored. Here,
we use density functional theory to calculate and manipulate the transition
energy of fluorescent defects in the two-dimensional material hexagonal boron
nitride. Our calculations feature the HSE06 functional which allows us to
accurately predict the electronic band structures of 267 different defects.
Moreover, using strain-tuning we can tailor the optical transition energy of
suitable quantum emitters to match precisely that of quantum technology
applications. We therefore not only provide a guide to make emitters for a
specific application, but also have a promising pathway of tailoring quantum
emitters that can couple to other solid-state qubit systems such as color
centers in diamond.
