Description of Interface Between Semiconductor Electrostatic Qubit and Josephson Junction in Tight Binding Model
Krzysztof Dominik Pomorski, Robert Bogdan Staszewski · Acta Physica Polonica A · 2020
The interface between a superconducting Josephson junction and a semiconductor position-based qubit implemented in coupled semiconductor q-dots is described as a possible base for an electrostatic interface between superconducting and semiconductor quantum computers.A modification of an Andreev bound state in a Josephson junction by the presence of a semiconductor qubit in its proximity and electrostatic interaction with a superconducting qubit is spotted by the minimalist tight-binding model.The obtained results allow for the creation of an interface between a semiconductor quantum computer and a superconducting quantum computer.The existence of topological states of matter is indicated.They open a perspective for the construction of QISKIT-like software that will describe both types of quantum computers as well as their interface.
