Building useful quantum technologies—from sensors to computers—requires generating highly complex entangled states, in which the properties of particles are deeply intertwined. Producing such states ...

We may receive a commission on purchases made from links. It was a fair question because that movie and many others toss around the word "quantum" like a magical explanation for technology a layperson ...

This video provides a simple explanation of symmetry and gauge theory, focusing on their foundational role in physics. It ...

Digital security currently relies on difficult equations to protect data. For example, when you use a credit card online, the ...

Bose-Einstein condensates (BECs) are often described as a "fifth state of matter": a quantum state in which many particles ...

It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's ...

Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line from one point to another. That seems obvious, because in the world we see ...

Performing complex algorithms on quantum computers will eventually require access to tens of thousands of hardware qubits. For most of the technologies being developed, this creates a problem: It’s ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

Welcome to the Physics World Quantum Briefing 2.0, which wraps up the International Year of Quantum Science and Technology (IYQ) and looks ahead to a quantum-enhanced future. This second instalment ...
