Innovation decoherence

The study of innovation in large companies and start-ups would benefit from being inspired by physics, which mobilizes different sets of laws for large masses and particles.

What is nothing? Martin Rees Q&A

From a mysterious energy of empty space to parallel universes, cosmology's view of 'nothing' is anything but boring.

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.

Experiment shows Einstein’s quantum ‘spooky action’ approaches the human scale

We usually think of quantum entanglement in the realm of atomic systems, but now it's been scaled up to relatively massive objects. This opens the door to new kinds of technology.

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.

Will artificial intelligence become conscious?

Researchers' views depend in part on what technology is (or will be) capable of – and in part on what consciousness actually is.

How quantum mechanics can change computing

As companies make quantum computers available through their cloud services, take a look at what it means for computing to move beyond classical mechanics and into quantum physics.

All you need for quantum computing at room temperature is some mothballs

Much of the current research in quantum computing involves work at close to absolute zero. A simple breakthough with an everyday material could see them work at more acceptable temperatures.

Beating cyber criminals with quantum solutions

As hackers get more sophisticated in their cyber crime efforts we need to look to new technology to make our systems more secure, and potentially unhackable. So how can quantum physics help?

Schrödinger’s cat gets a reality check

It’s a century-old debate: what is the meaning of the wave function, the central object of quantum mechanics? Is Schrödinger’s cat really dead and alive? I was recently involved in an experiment conducted…
