Abstract Cooper pairs occupy the ground state of superconductors and are typically composed of maximally entangled electrons with opposite spin. In order to study the spin and entanglement properties of these electrons. one must separate them spatially via a process known as Cooper pair splitting (CPS). Here we provide the first demonstration of CPS in a semiconductor two-dimensional ... https://www.spidertattooz.com/Quilters-Select-6x24-Ruler-by-Alex-Anderson/
