When we measure a qubit in superposition, it picks one state, like a spinning coin landing heads or tails. This is called ...

So, you’ve heard about quantum teleportation, maybe from sci-fi shows or news headlines. It sounds like something ...

Quantum computers have become the latest canvas for humanity’s oldest fantasy: escaping death. Startups, futurists, and speculative essays now suggest that machines built to manipulate qubits could ...

In this video, we delve into quantum entanglement, famously described as “spooky action at a distance” by Albert Einstein.

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

The promise of quantum computers appears to be that they will upend modern computing as we know it. With exceptional computational power, they’ll be performing feats unimaginable for any classical ...

After decades spent gestating in labs, quantum computing has finally reached an inflection point between theoretical promise and practical implementation. From discoveries in pharmaceutical and ...

“In quantum computers, information is transmitted and stored using so-called qubits (quantum bits). But quantum information ...

Dr. Dominic Williamson, a University of Sydney quantum physicist, has developed a new approach to quantum error correction that could significantly reduce the number of physical qubits required to ...
