Tiny fluorescent semiconductor dots, called quantum dots, are useful in a variety of health and electronic technologies but are made of toxic, expensive metals. Nontoxic and economic carbon-based dots are easy to produce, but they emit less light. A new study including researchers from the University of Illinois at Urbana-Champaign uses ultrafast nanometric imaging found good and bad emitters among populations of carbon dots.

In the October issue of Nature Communications, a team of IQUIST researchers led by Kejie Fang, Assistant Professor in Electric and Computer Engineering, present a new method for efficiently trapping phonons inside a fabricated device. Their design reduces heating by keeping some phonons stuck in place while redirecting others, and the heat they carry, to a completely different part of the device.

In a breakthrough for quantum computing, University of Chicago researchers have sent entangled qubit states through a communication cable linking one quantum network node to a second node. The researchers, based in the Pritzker School of Molecular Engineering (PME) at the University of Chicago, also amplified an entangled state via the same cable first by using the cable to entangle two qubits in each of two nodes, then entangling these qubits further with other qubits in the nodes.
