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

    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).Show notes: http://frontiers.physicsfm.com/79

    Quantum Machine Learning with Bruna Shinohara

    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.

    Maxwellian Ratchets with Alex Jurgens

    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.http://frontiers.physicsfm.com/77

    Categorical Probability and the Measurement Problem

    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.Show Notes: http://frontiers.physicsfm.com/75

    Stochastic Thermodynamics with David Wolpert

    Jim talks with David Wolpert about the non-equilibrium behavior of computation, what it means for entropy, and how it relates to traditional thermodynamics.Show Notes: http://frontiers.physicsfm.com/74

    Quantum Money with Jiahui Liu

    Jim discusses quantum money with Jiahui Liu.  Quantum money is a linchpin of quantum cryptography.  The ability to create secure banknotes using quantum computers would allow even more secure methods of encryption for communications.

    Born Rule and Gravity with Antony Valentini

    Jim talks with Antony Valentini about the difficulties of interpretation of quantum mechanics in light of quantum gravity.  In particular, Antony discusses the failure of the Born Rule due to the impossibility of normalization (the fact that probabilities must sum to 100%) at that scale, and therefore the need to interpret the wavefunction as something more than merely the knowledge of the observer about the system.  They spend some time talking about the de Broglie-Bohm interpretation in light of quantum gravity.Show Notes: http://frontiers.physicsfm.com/72
