Quantum systems hold the promise of tackling some complex problems faster and more efficiently than classical computers. Despite their potential, so far only a limited number of studies have ...

While usual gapless points that are not geometrically defective i.e. Dirac points (Left column) possess only eigenvalues within [0, 1] (Bottom Left), defective exceptional points (Right column) also ...

An IBM processor revealed a transition from scrambling to control, demonstrating repeated quantum feedback across up to 100 ...

Once described by Einstein as "spooky action at a distance," quantum entanglement may now seem less intimidating in light of new research findings. Osaka Metropolitan University physicists have ...

Do I need a spaceship to go to the outside of the universe?Recently, I have been researching various aspects of quantum ...

Quantum teleportation has moved from science fiction into laboratory reality, but not in the way popular culture imagines. Instead of beaming people or objects across space, physicists are learning ...

Recently, even when I look at AI news, there is a technology that I find even more intriguing.Quantum networks.No, this is ...

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...

It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's ...

Performing complex algorithms on quantum computers will eventually require access to tens of thousands of hardware qubits. For most of the technologies being developed, this creates a problem: It’s ...

Quantum entanglement is a foundational phenomenon in quantum mechanics where two or more particles become interconnected in such a way that the state of one particle instantly influences the state of ...
