Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

Replication is a cornerstone of science, yet even in the natural sciences, attempts to reproduce results do not always succeed. Quantum computing promises machines that can solve certain problems far ...

Would it be possible to control and even reverse the flow of time in a laboratory setting? While taking a trip back through ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the smallest scales, erasing information is not free, it consumes energy and ...

A team of researchers at the University of Waterloo have made a breakthrough in quantum computing that elegantly bypasses the fundamental "no cloning" problem. The research, "Encrypted Qubits can be ...

Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly "conversion table" that works on a laptop and returns results within hours. When ...

A new study in Nature Physics has turned an old problem on its head by reporting a way to use the noisy interactions between ...

Quantum computing promises extraordinary power, but that same power may expose new security weaknesses. Quantum computers are expected to deliver dramatic gains in processing speed and capability, ...
