Episode 79: Primordial Black Holes with QCD Color Charge with Elba Alonso-Monsalve and David Kaiser

Wed, 04 Sep 2024

Jim talks  with Elba Alonso-Monsalve and David Kaiser about the prospects to describe dark matter as tiny black holes that were created at the end of cosmic inflation.  Due to the large inhomogeneities in the distribution of matter at that time, the black holes could form directly from the matter distribution and not be color neutral (in the sense of QCD).

Episode 78: Quantum Machine Learning with Bruna Shinohara

Fri, 31 May 2024

Jim talks with Bruna Shinohara of CMC Microsystems. Quantum computing and machine learning are both currently making huge strides.  So it is not strange that people are trying to use quantum computing for machine learning.


Episode 77: Maxwellian Ratchets with Alex Jurgens

Sun, 31 Mar 2024

Jim talks with Alex Jurgens about Maxwellian ratchets, automata that are similar to Maxwell's Demon.  They talk about their implications for information processing and entropy.

Episode 75: Categorical Probability and the Measurement Problem

Sun, 20 Aug 2023

Jim talks with Nick Ormrod and V. Vilasini about their use of categorical probability theory to analyze the measurement problem.  We discuss categorical probability theory, which allows them to abstract from particular mathematical formulations of quantum mechanics to more general ideas about states and measurements and observers than found in Hilbert space formulations.  They use this to look at the various properties of quantum mechanics and how they relate to each other, in particular how relativity affects the measurement problem.
