Quantum Hybrid Interconnects: Superconducting Qubits and Spins
Abstract: Current quantum platforms possess unique strengths and weaknesses that are complementary to each other. Hybrid systems are a natural way towards exploring quantum information processing and improving the weakness of any one platform. In this talk, I am going to focus on one of these hybrid systems, the pairing of spins in solids and superconducting circuits. Superconducting circuits are known for their fast and flexible control through tuneable coupling elements, while spin systems have long coherence times. However, the manipulation of coherent spins for quantum control is nontrivial due to weak coupling to their environment. High spin density magnetic materials, such as YIG , are a promising testbed to help address this coupling strength challenge and design an architecture that integrates both superconducting circuits and spins. YIG spheres have transitions in the correct microwave frequency regime and exhibit strong coupling with superconducting circuits. This talk will focus on building parametrically controlled coupling mechanisms between a superconducting element and a spin system to exploit the beneficial characteristics of both systems.
