In Zeno’s paradox, Greek hero Achilles races a tortoise but can never reach it, revealing a timeless puzzle about motion and ...

A quantum attack on Bitcoin would crash its price before any theft settles, moving the real risk to confidential data.

In holographic theories, physicists may have traced the pliability of space-time to its quantum roots: a measure of ...

A message from the future sounds like science fiction, until someone starts asking how many bits it could actually carry. That is the question three physicists have now answered, using a setup ...

Researchers propose that extra-dimensional spacetime torsion prevents black holes from fully evaporating, leaving remnants that preserve quantum information. Credit: SciTechDaily.com A new theoretical ...

One of the film’s most memorable scenes shows Cooper sending messages to his daughter from inside a black hole. While the sequence was designed as science fiction, new research suggests the underlying ...

Can you send messages in the past to someone? Time travel messages come with a paradox: if you send a message to the past which changes the future, no one is really sending the messages in the first ...

The scene from Interstellar is iconic: a father stranded in the future, tapping messages to his daughter, who lives decades in his past. Every physicist who ever watched it registered the same thought ...

The latest trends in software development from the Computer Weekly Application Developer Network. Sometimes classed as a Japanese startup, OptQC works with optical photonic technologies to develop a ...

Unlike regular computers, quantum machines use qubits, which can be zero and one simultaneously, allowing them to explore many computational possibilities at once ...

Scientists in Japan have developed a new way to instantly detect elusive quantum “W states,” a major milestone for quantum technology. The breakthrough could help unlock faster quantum communication, ...

To get quantum computing to work, we will ultimately need lots of high-quality qubits, which we can tie together into groups of error-corrected logical qubits. Companies are taking distinct approaches ...
