Building the Next Generation of Spin Qubits
Quantum computers have the potential to be a transformative technology. While there are many possible platforms for developing a viable quantum computer, spin qubits offer several unique advantages, such as their potential for scaling using established semiconductor manufacturing techniques. However, they face a number of challenges, largely stemming from their sensitivity to the environment. In this talk, I will discuss my research on combating this sensitivity by increasing coherence times and enabling long-distance coupling in spin qubits. I will then present two projects in which the development of novel materials and devices enabled the discovery of new physics and functionalities; first, a study of unconventional superconductivity in infinite-layer nickelate and second, an investigation of sources of decoherence in superconductingqubits. These projects demonstrate how active control of material heterostructures can be leveraged to design systems with desired traits. I will show how such an approach can be fruitful for the study of spin qubits, allowing fine control of their properties and leading to improved quantum devices to implement more complex quantum architectures.
