What makes something quantum? This question has kept a small but dedicated fraction of the world's population—most of them ...

A model for dense degenerate plasmas that incorporates electron spin indicates that quantum effects can be seen even under conditions previously considered to be in the classical regime.

This 50-50 ratio over the binary (+1 and -1) outcomes is what physicists are talking about when they say that a vertical spin up electron is in a quantum superposition of horizontal spins left and ...

This single electron then can then be in multiple ... atoms," exhibiting quantised states similar to the superposition states of a spin qubit. What's new about Intel’s chip?
