How to make bright quantum dots even brighter

Quantum dots are a kind of artificial atom: just a few nanometers in size and made of semiconductor materials, they can emit light of a specific color or even single photons, which is important for quantum technologies. The ...

Creating 3D-printed materials that shrink more precisely

From houses to hearing aids, three-dimensional (3D) printing is revolutionizing how we create complex structures at scale. Zooming down to the micro and nano levels, a process known as two-photon polymerization lithography ...

Forming and sensing optical emitters in real time

Seeking new techniques to enable quantum networking, Harvard University researchers have developed a novel laser-based strategy for creating single-atom, near-surface material defects, which can be used to form qubits, the ...
