A novel microscope operates on the quantum state of single electrons
Artistic illustration of the integration of electron spin resonance in atomic force microscopy. The white structure at the bottom represents a single molecule, the arrows its spin quantum state and…
The ‘marriage’ of 2D materials and 0D quantum dots

Researchers show an old law still holds for quirky quantum materials
An illustration shows strongly interacting electrons carrying heat and charge from warmer to cooler regions of a quantum material. A theoretical study by SLAC, Stanford and the University of Illinois…
Researchers invent new way to stretch diamond for better quantum bits
By “stretching” thin films of diamond, researchers have created quantum bits that can operate with significantly reduced equipment and expense. Credit: Peter Allen A future quantum network may become less…
Quantum tool opens door to uncharted phenomena
The temperature profiles obtained by the researchers show that particles that interact strongly with the environment are “hot” (red) and those that interact little are “cold” (blue). Entanglement is therefore…
