A single quantum AI 'brain cell' can predict the future better than a regular one, even when they’re looking at the exact same data.

The Takeaway
Researchers found that quantum versions of basic AI components have a built-in mathematical advantage that allows them to see patterns classical systems miss. This suggests that 'quantum thinking' might be inherently superior for machine learning, even without increasing the amount of information the system has access to.
From the abstract
In the current world, the use of artificial intelligence is penetrating every aspect of human life. The basic element of any artificial intelligence is a digital neuron, called a perceptron, while its quantum analogue is called a quantum perceptron. Here, we introduce a model of perceptron called the informationally-restricted measurement-based perceptron (IMP), where each input is composed of two bits, while at the node, depending on a free input variable, the perceptron decides which bit to ev
