Quantum computing, the new frontier of finance

On October 23 Google announced that it built a quantum computer thousands of times faster than classic computers. This could have immense impacts on finance, cryptography and other fields.

In the future, everyone might use quantum computers

Computers were once considered high-end technology, only accessible to scientists and trained professionals. Today, almost everyone has one. Will quantum computing follow the same path?

We’ve designed a ‘flux capacitor’, but it won’t take us Back to the Future

Physicists have designed an electrical component that breaks time-reversal symmetry. Not quite the time machine from Hollywood but it should help with communication technology and quantum computing.
After this episode, you’ll be able to explain how quantum mechanics affects everything from the way your jeans are cut to the headphones you use. Cindy Zhi/The Conversation NY-BD-CC

Quantum speed limit may put brakes on quantum computers

A future that continues to have increasingly fast computing depends on quantum physics – but research is showing that there are limits to how fast quantum computers can go.
