(author), Dvir, T. (author), Wimmer, M.T. (author), Goswami, S. (author)Artificial Kitaev chains can be used to engineer Majorana bound states (MBSs) in superconductor–semiconductor hybrids1,2,3,4. In this work, we realize a two-site Kitaev chain in a two-dimensional electron gas by coupling two quantum dots through a region proximitized by a superconductor. We demonstrate systematic control over inter-dot couplings...journal article 2024

Wang, Q. (author), ten Haaf, S.L.D. (author), Kulesh, I. (author), Xiao, Di (author), Thomas, Candice (author), Manfra, Michael J. (author), Goswami, S. (author)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...journal article 2023
