Discovery of a New Electronic State of Matter May Advance Second Quantum Revolution

Key points…

+  Discovery shows electrons can bind together in ways similar to how quarks combine to form neutrons and protons.

Levy, who is also director of the Pittsburgh Quantum Institute, noted that the new particles feature properties related to quantum entanglement, which can potentially be used for quantum computing and quantum redistribution. He said the discovery is an exciting advancement toward the next stage of quantum physics.

“In the first quantum revolution people discovered the world around them was governed fundamentally by laws of quantum physics. That discovery led to an understanding of the periodic table, how materials behave and helped in the development of transistors, computers, MRI scanners, and information technology.  

“Now in the 21st century, we’re looking at all the strange predictions of quantum physics and turning them around and using them. When you talk about applications, we’re thinking about quantum computing, quantum teleportation, quantum communications, quantum sensing — ideas that use properties of the quantum nature of matter that were ignored before.”

+  Jeremy Levy, a distinguished professor of condensed matter physics, and Patrick Irvin, a research associate professor are coauthors of the paper “Pascal conductance series in ballistic one-dimensional LaAIO3/SrTiO3 channels.” The research focuses on measurements in one-dimensional conducting systems where electrons are found to travel without scattering in groups of two or more at a time, rather than individually.

+  “Normally, electrons in semiconductors or metals move and scatter, and eventually drift in one direction if you apply a voltage. But in ballistic conductors the electrons move more like cars on a highway. The advantage of that is they don’t give off heat and may be used in ways that are quite different from ordinary electronics. Researchers before us have succeeded in creating this kind of ballistic conductor,” explained Levy.
