Recorded: 2025/01/08 Released: 2025/09/30

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.

Recorded: 2024/12/19 Released: 2025/02/09

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.

Primordial Black Holes with Elba Alonso-Monsalve and David Kaiser

← Previous ( Quantum Machine Learning )

( Decoherent Histories & Many Worlds ) Next →

Recorded: 2024/07/03 Released: 2024/09/03

Jim talks with Elba Alonso-Monsalve and David Kaiser about the prospects of a class of primordial black holes as a candidate for dark matter. These tiny black holes form just after the inflationary epoch when it is possible for them to form from inhomogeneities wihtout a prior history as a star. Black holes forming during this time time-frame would not have to be color neutral as baryons and mesons are.

Recorded: 2023/12/18 Released: 2024/03/31

Jim talks with Alex Jurgens of INRIA about Maxwellian Ratchets. These are abstract machines that react to outside stimuli, These are highly specified theoretical realizations of Maxwell's Demon, who flaunts the second law of thermodynamics. Jurgens discusses these in terms of entropy, information processessing, and the second law.
