Understanding and reliably measuring the geometric properties of quantum states can shed new light on the intricate underpinning of various physical phenomena. The quantum geometric tensor (QGT) is a ...

MIT physicists and colleagues have for the first time measured the geometry, or shape, of electrons in solids at the quantum level. Scientists have long known how to measure the energies and ...

Figure 1: Quantum objects such as electrons, protons and neutrons are notoriously difficult to pin down due to Heisenberg’s uncertainty principle. Now, two RIKEN researchers have derived analogous ...
