Quantum nonlocality may be inherent in the very nature of identical particles

Nonlocality seems to be enchanted into such a fundamental property of our universe as the indistinguishability of quantum particles. Credit: IFJ PAN, AI At its deepest physical foundations, the world…

Quantum ‘pinball’ state of matter in electrons allows both conducting and insulating properties, physicists discover

Breakthrough could connect quantum computers at 200X the distance

New research from University of Chicago Pritzker School of Molecular Engineering (UChicago PME) Asst. Prof. Tian Zhong could make it possible for quantum computers to connect at distances up to…

Physicists observe key evidence of unconventional superconductivity in magic-angle graphene

Physicists use a new platform to measure magic-angle graphene’s superconducting gap. The method involves “tunneling” electrons between two layers of magic-angle twisted tri-layer graphene (in yellow) while measuring the material’s…

Two independent quantum networks successfully fused into one

Photoinduced non-reciprocal magnetism effectively violates Newton’s third law

A non-reciprocal phase transition to a many-body, time-dependent chiral phase occurs in layered ferromagnets. Credit: Institute of Science Tokyo A theoretical framework predicts the emergence of non-reciprocal interactions that effectively…

New model can detect ballistic electrons under realistic conditions

While energy is dissipated in the form of heat when electrons flow in the 2D material, this is not the case in the edge channel—resulting in a characteristic energy and…
