Title:
METHOD FOR CALIBRATING AND/OR ASSISTING IN THE DESIGN OF A SPIN-QUBIT OR TWO-LEVEL QUANTUM SYSTEM AND QUANTUM COMPONENT
Document Type and Number:
WIPO Patent Application WO/2023/175071
Kind Code:
A1
Abstract:
The invention relates to a method for calibrating a two-level spin quantum system coupled to a microwave cavity by a symmetric magnetic field and an antisymmetric magnetic field in the form of a double quantum dot comprising a left dot and a right dot, which system is subjected to a bias voltage, the method being characterised by the following steps: - setting the bias voltage (ε) to zero volts; - determining a wave function φp of each of the quantum dots; - calculating and/or setting the antisymmetric αas and symmetric αs magnetic coupling constants, calculating and/or setting the tunnel coupling constant, and/or the symmetric magnetic coupling constant αs and/or the antisymmetric magnetic coupling constant αas.
