Why Cant You Use Quantum Mechanics To Communicate Faster Than Light?
The EPR paradox, that we met in a previous video, tells us 2 entangled particles can effect each other no matter now far away they are. But then why cant we use them to send instant messages across the universe? Einsteins relativity...

Krister Shalm Explains NIST's Participation in the BIG Bell Test
NIST physicist Krister Shalm talks about NIST's participation in the November 30, 2016, BIG Bell Test, a worldwide project to bring human unpredictability (randomness) to cutting-edge physics experiments. But it's not just NIST...

What is quantum computing? Its evolution, uses cases and how to access it
You may have heard of quantum computing, but what is it, and what problems can it solve? Plus, what makes quantum computing different from classical computing, and how can enterprises access and harness the technology? Serdar Yegulalp,...

Spaceships pushed by LIGHT – the future of space travel?
What if you could power a ship using sunlight instead of wind? Well in space, you can! Solar sails or light sails are pushed with light from the sun. Photons provide a kick when they reflect off the sail pushing the sail like an air...

What does a Physics Major do? (Part 2 Research and Career Examples)
Our part 2 video of "What does a physics major do" covers what research positions and jobs a physics major could go into. In the video I focus mostly on jobs that directly apply to physics. What you'll find is that there are an endless...

The Quantum Barrier Potential Part 1: Quantum Tunneling
Now that we've covered the particle in a box, we are familiar with the concept of a quantum problem. Let's move on to our second quantum problem, that of the quantum barrier potential. With this one, we don't have an infinite square well...
