Autonomous robots need something like a physical intuition in order to plan their movements and interact with the physical environment, but many AI models struggle with this worldliness. A recent model takes a different approach to learn about its surroundings.

If all objects are quantum mechanical — including big objects like ourselves — how does the reality we experience emerge from the bizarre quantum behavior of electrons and other particles?

But in the mid-80s, Clarke, Devoret, and Martinis were pursuing a fundamental question: Is quantum mechanics a universal theory that applies to all objects big and small? Their work, and subsequent work, suggest that it is.

These superconducting quantum gadgets lie at the heart of some of today’s most sophisticated quantum computers, where they act as “qubits” that can easily handle certain calculations that are harder for conventional computers.

Google and IBM Clash Over Quantum Supremacy Claim
Today Google announced that it achieved “quantum supremacy.” Its chief quantum computing rival, IBM, said it hasn’t. The disagreement hinges on what the term really means.

In the 1980s at UC Berkeley, Devoret and Martinis built devices with two superconducting wires separated by a material that blocked electricity. Nevertheless, electrons were able to “tunnel” through the barrier — a purely quantum phenomenon.

After centuries of effort, scientists have largely succeeded in digitally reconstructing the Earth in order to ask how its climate will change in the future. Now, not liking the answer, some are reaching to unplug the machine.

Babies love peek-a-boo because it plays with their developing notion of object permanence. V-JEPA, an AI model recently built at Meta, similarly exhibits “surprise” when its predictions of the real world fail to match its observations.

Climate change contains feedback loops. A warmer atmosphere, for example, can hold more water, which in turn doubles the total warming and draws even more water into the air.

This year, the physicist Patryk Lipka-Bartosik and his colleagues built a thermometer of sorts to spy on entangled qubits inside quantum computers and other quantum systems. www.quantamagazine.org/a-thermomete...

An AI model called V-JEPA is capable of “intuiting” the physical properties of the real world, gaining a sense of object permanence, the constancy of shape and color, and the effects of gravity. @anilananth.bsky.social reports:
