A new theory of quantum subsystems

When studying a complex system, scientists identify smaller pieces called subsystems that they can make sense of. By studying subsystems and the correlations between them, they reconstruct an understanding of the whole.

The structure of the smallest semiconductor elucidated

A semiconductor is a material whose conductivity lies somewhere between that of a conductor and an insulator. This property allows semiconductors to serve as the base material for modern electronics and transistors. It is ...

Quantum computer works with more than zero and one

We all learn from early on that computers work with zeros and ones, also known as binary information. This approach has been so successful that computers now power everything from coffee machines to self-driving cars and ...

Researchers create order from quantum chaos

In a new paper in PNAS, "Triplet-Pair Spin Signatures From Macroscopically Aligned Heteroacenes in an Oriented Single Crystal," National Renewable Energy Laboratory (NREL) researchers Brandon Rugg, Brian Fluegel, Christopher ...

Quantum sensor can detect electromagnetic signals of any frequency

Quantum sensors, which detect the most minute variations in magnetic or electrical fields, have enabled precision measurements in materials science and fundamental physics. But these sensors have only been capable of detecting ...
