A study by graduate students Hao Tang and Guoqing Wang, and profs Ju Li and Paola Cappellaro, shows neutrons can bind to nanoscale atomic clusters known as quantum dots. The finding may provide insights into material properties and quantum effects.

The method lets researchers identify and control larger numbers of atomic-scale defects, to build a bigger system of qubits.

Nominated by the Division of Atomic, Molecular & Optical Physics, Professor Cappellaro was cited, “[f]or groundbreaking contributions to quantum control and quantum sensing with spin systems.”

NSE’s Guoqing Wang, Paola Cappellaro and Ju Lishow that they may be able to develop new quantum sensors or quantum simulations by fine-tuning the spin density in some materials.

For years, researchers have tried various ways to coax quantum bits — or qubits, the basic building blocks of quantum computers — to remain in their quantum state for ever-longer times, a key step in creating devices like quantum sensors, gyroscopes and...

Using lasers, NSE's Ju li, Paola Cappellaro, Haowei Xu and other researchers can directly control a property of nuclei called spin, that can encode quantum information.

MIT engineers expand the capabilities of these ultrasensitive nanoscale detectors, with potential uses for quantum computing and biological sensing.

Mathematical simulations show the new approach may offer faster, cheaper, and more accurate detection, including identifying new variants.

Physicists and engineers have long been interested in creating new forms of matter, those not typically found in nature. Such materials might find use someday in, for example, novel computer chips. Beyond applications, they also reveal elusive insights about the fundamental workings...

The study’s result can be seen as one solution to the open problem of how work and heat are defined in open quantum systems. Understanding the laws of classical thermodynamics allows for many of the modern technologies we take for granted today,...
