Advances in the control of 133Ba+ Qubits

POSTER

Abstract

This poster highlights key advancements in controlling ¹³³Ba⁺(Barium-133) ion qubits, a promising candidate for quantum computing. We focus on innovative methods for initializing, manipulating, and reading out the quantum states of ¹³³Ba⁺ qubits, utilizing the single species approach of the omg protocol. Our research explores improved coherence times and reduced error rates through microwave and Raman gates. We address the use of ¹³³Ba⁺ ions in scalable quantum architectures, such as integrated photonics and demonstrate its advantages over other ion species in operational stability and decoherence minimization. This work represents a significant step towards realizing efficient and scalable quantum computers, leveraging the unique properties of ¹³³Ba⁺.
