Jim talks with Koustubh Phalak about quantum random access memory (QRAM), a proposed technology that would allow the storage of quantum states in qunatum computation. Koustubh discusses quantum computing, the need for QRAM, proposed implementations of QRAM, and some of the difficulties in its implementation. ------------------------------------------- Notes: 1.

Jim talks with Philip Tee about the effects of having a pixelated space time. Phil uses doubly special relativity and quantum feild theory to explore models for spacetimes that are fundmentally discrete. Here he looks for tangible results in light bending and the Casimir effect.
