Entry in the FQXi 2008 Essay Contest on The Nature of Time: Whither Time’s Arrow?
In our everyday lives we have the sense that time flows inexorably from the past into the future; that time has a definite direction; and that the arrow of time points towards a future of greater entropy and disorder. But in the microscopic world of atoms and molecules the direction of time is indeterminate and ambiguous.
Amica Conference: Thermodynamic Approaches to Artificial Intelligence. March 9-11, 2026, Karuizawa, Japan.
Notes on the circuit model of quantum computing. Currently mostly an exposition on the menagerie of quantum gates.
We show that natural gradient descent can have a similar computational complexity per iteration to a first-order method, when employing appropriate hardware.
Physics-based Application-Specific Integrated Circuits present a transformative paradigm by directly harnessing intrinsic physical dynamics for computation.
