摘要
Since the landmark Nature paper by Kielpinski et al in 2000 describinga technology for scalable quantum computation (part of the work for whichWineland was co-awarded the 2012 Nobel prize in physics), interest inpractical quantum computation has grown significantly. Recent announcementsby commercial effort Dwave of a 128-quantum-bit adiabatic system,although controversial in terms of its quantum properties, illustratethe engineering progress that has been made.In this talk, I will present a basic quantum computing architecture basedupon trapped-ion technology. I will examine several challenges to scalingthis architecture and explore adaptations of traditional computer systemssolutions towards these challenges. Specifically, I will introduce aninterconnection network that uses quantum teleportation to addressreliability and latency challenges in long-distance communication.I will present a quantum memory hierarchy to decrease the area andperformance penalties resulting from quantum error correction.Finally, I will discuss work that explores static and dynamic compilationstrategies for generating quantum machine code which approximatearbitrary quantum rotations, an important primitive in many quantumalgorithms.
