Do decoherence, gravity, dark matter and dark energy all originate from quantum corrections?
Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely believed to consist of dark matter and dark energy. Paradoxically, however, the nature of these dark ...
Scientists take a step toward a quantum internet using New York City's fiber
As long as there's been an internet, there's been a way to hack it. Scientists have spent decades imagining a different kind of network, one where the laws of physics make eavesdropping physically impossible, not just technically ...
