Imagine trying to design a key for a lock that is constantly changing its shape. That is the exact challenge we face in ...

The Bitcoin network took its first step towards quantum-computing resistance with the addition of BIP 360 to its repository.

This paper proposes a minimal, substrate-neutral ontology grounded in three irreducible modal operations: execution, interaction, and memory. These operations—corresponding to existence, possibility, ...

There’s only a few days left in the International Year of Quantum Science and Technology, but we’re still finding plenty to celebrate here at Physics World HQ thanks to a long list of groundbreaking ...

Dualities in physics have challenged traditional forms of scientific realism by undermining the idea that theories describe a unique underlying ontology. In this paper, we develop a new perspective on ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

Elon Musk called Bitcoin a “physics-based currency” tied to energy and suggested that advances in AI and robotics could eventually make money obsolete. Tesla and SpaceX CEO Elon Musk has reignited ...

Physicist Paul Davies’s Quantum 2.0: The past, present and future of quantum physics ends on a beautiful note. “To be aware of the quantum world is to glimpse something of the majesty and elegance of ...

Researchers created scalable quantum circuits capable of simulating fundamental nuclear physics on more than 100 qubits. These circuits efficiently prepare complex initial states that classical ...

In the 1960s, a group of physicists and historians began a massive project meant to catalogue and record the history of quantum physics. It was called Sources for History of Quantum Physics (SHQP). As ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...
