Quantum entanglement is challenging researchers to understand how photons seemingly influence each other instantaneously.

This new study meticulously mapped photon states in these nanoscale systems. The researchers demonstrated quantum ...

Using QFI, the researchers tracked the origin of this quasiparticle loss to how electron spins become entangled, finding that entanglement reaches its peak precisely at this quantum critical point.

“We’ve demonstrated that quantum entanglement can be preserved over incredibly long distances using satellite ... of ...

134.080201) Physicists at the Georgia Institute of Technology, US have introduced a novel way to generate entanglement between photons – an essential step in building scalable quantum computers that ...

The team introduced a method called variational entanglement witness (VEW), using a quantum algorithm that optimizes entanglement detection. Unlike traditional methods, which often fail to ...

In particular, the security of devices using quantum entanglement can be enhanced by tests based on the results of observations made at each instant, rather than on the physical properties of the ...

Using QFI, the researchers tracked the origin of this quasiparticle loss to how electron spins become entangled, finding that entanglement reaches its peak precisely at this quantum critical point.

Physicists used quantum tools to reveal that electrons in strange metals become highly entangled at a tipping point, offering insights for future superconductors. Unlike conventional metals such as ...
