It from Qubit with Grant Salton

Kevin and Sebastian are joined by Grant Salton, a quantum researcher at AWS, who helps us understand a recent paper from Google and Caltech whose authors describe a simulation of a wormhole on Google's Sycamore quantum computer. The paper stirred some controversy and push back on the misunderstanding of the claims being made, and Grant walks us through a sub-domain of quantum information science called "it from qubit," which seeks to bridge elements of astrophysics with concepts from quantum information. Mentioned in the episode:The Nature paper from Google and Caltech describing the wormhole experiment and findings. Some context from Caltech blog.John Wheeler's paper: "Information, Physics, Quantum: The Search for Links" which coined "it from bit."A BBC article describing the "quantum hair" solution to Hawking's black hole information paradox.The Edge of All We Know, a terrific documentary that traces the efforts to solve the information paradox in parallel with the effort to capture an image of a black hole. 

Om Podcasten

Your hosts, Sebastian Hassinger and Kevin Rowney, interview brilliant research scientists, software developers, engineers and others actively exploring the possibilities of our new quantum era. We will cover topics in quantum computing, networking and sensing, focusing on hardware, algorithms and general theory. The show aims for accessibility - neither of us are physicists! - and we'll try to provide context for the terminology and glimpses at the fascinating history of this new field as it evolves in real time.
