Engineering the Quantum Computer: Two Case Studies

Continuous advancements in the performance of solid state qubits make it feasible to try to make scalable quantum information processing system in the coming years.  But many further improvements will be needed in various working parts of a system besides the qubits themselves.  I will discuss two case studies in this direction from my recent work, first in the area of direct measurements of multi-qubit parity in qubit-cavity systems, and next in the area of potential improvements to the microwave circulator, a ubiquitous component needed in signal-handling in the quantum computer.
