Quantum physics is quietly rewriting the rulebook for how far and how fast humanity might travel beyond Earth. A cluster of ...

Cybersecurity experts often warn that a moment known as Q-Day is nearby—a day when quantum computers will become powerful enough to break all the encryption methods we currently rely on to keep our ...

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

Warp drives have long lived in the realm of science fiction, but the underlying physics that inspired them is very real and surprisingly precise. As researchers probe the edges of general relativity ...

Scientists have taken one more step down the very long road to time travel. A new paper combines the Alcubierre “warp” drive with the idea of “controlled closed timelike curves.” Though far out, ...

Using a quantum computer to simulate time travel, researchers have demonstrated that, in the quantum realm, there is no "butterfly effect." In the research, information—qubits, or quantum bits—'time ...
