A New Era in Quantum Mechanics Is Here... | Jacob Barandes
Theories of Everything with Curt Jaimungal
The Quirky Origins of the Qubit
This chapter explores the origins and etymology of the term 'qubit,' a key concept in quantum information theory. It highlights the word's playful connection to the biblical unit 'cubit' and examines the relationship between classical and quantum concepts.

In this captivating of Theories of Everything, Jacob Barandes and I delve into the intricate world of Indivisible Stochastic Processes and their profound impact on quantum mechanics. We explore how these non-Markovian systems introduce quantum phenomena like superposition and interference without the traditional wave function collapse.
