Sounding the Drums to Listen for Gravity’s Effect on Quantum Phenomena
A bench-top experiment could test the notion that gravity breaks delicate quantum superpositions.

Watching the Observers
Accounting for quantum fuzziness could help us measure space and time—and the cosmos—more accurately.

Bohemian Reality: Searching for a Quantum Connection to Consciousness
Is there are sweet spot where artificial intelligence systems could have the maximum amount of consciousness while retaining powerful quantum properties?

Quantum Replicants: Should future androids dream of quantum sheep?
To build the ultimate artificial mimics of real life systems, we may need to use quantum memory.

Painting a QBist Picture of Reality
A radical interpretation of physics makes quantum theory more personal.

Quantum Reality Check
Photon experiments suggest the wavefunction is real -- and quantum cats truly are dead and alive at the same time -- as physicists Alessandro Fedrizzi and Martin Ringbauer explain. Plus, FQXi releases its first two books.

Detecting Black Hole Firewalls
If you fell into a black hole would you be stretched into spaghetti or would you catch fire? Cosmologist Niayesh Afshordi discusses the possibility that neutrinos detected on Earth hold the answer. They may have been created by a ring of fire surrounding back holes.

Our latest podcast has been posted and we’re catching up with a couple of old friends of FQXi to talk about their recent work, and making a couple of new ones.

First up we have quantum physicist Martin Ringbauer, of the University of Queensland, discussing tests investigating whether the quantum wavefunction is real. You may remember that Martin took part in one of our most popular podcast pieces last year, when he chatted to us about simulating time travel in the lab with photons. Now,...
