Engineering Signal Integrity in Multi-qubit Devices: Part II
ORAL
Abstract
Rapidly increasing complexity of quantum hardware presents novel engineering challenges in cryogenics and microwave design. The issue of signal integrity comes to the forefront when designing a collection of individually-addressable qubits that share an electromagnetic environment. Engineering that environment properly is imperative to reducing cross-talk and loss, and ensuring that gate operations can be performed with high fidelity. Recent progress in novel fabrication techniques and practice is presented, showcasing a set of advancements that significantly improve signal isolation and reduce loss.
