The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers.
Computer scientists established a new boundary on computationally verifiable knowledge. In doing so, they solved major open problems in quantum mechanics and pure mathematics.
A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.
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.
Researchers finally seem to have a quantum computer that can outperform a classical computer. But what does that really mean?
Fifty years after the current internet was born, the physicist and computer scientist Stephanie Wehner is planning and designing the next internet — a quantum one.
Researchers are getting close to building a quantum computer that can perform tasks a classical computer can’t. Here’s what the milestone will mean.
A recent test has confirmed the predictions of quantum trajectory theory.
Pure, verifiable randomness is hard to come by. Two proposals show how to make quantum computers into randomness factories.
