According to recent reports, scientists have successfully transmitted entangled photons through existing fiber-optic cables beneath New York City's streets, marking a significant advancement in quantum technology and paving the way for the development of a quantum internet.

The Event Horizon Telescope (EHT) collaboration has achieved a groundbreaking advancement in black hole imaging, enabling scientists to observe these cosmic phenomena in "color vision" for the first time. By incorporating a new radio frequency of 345 GHz alongside the existing 230 GHz, researchers can now produce sharper, more detailed images of supermassive black holes and gain deeper insights into the complex physics surrounding these enigmatic objects.

Scientists from the University of Toronto have made a surprising discovery in quantum physics, observing what they describe as "negative time" in an experiment involving photons and atomic excitation. The study, which has been submitted for peer review, was reported by The Independent. Researchers found that under certain conditions, photons appeared to exit a cloud of ultracold atoms before entering it. This finding challenges our conventional understanding of time in the quantum realm.

Recent advancements in attosecond-level measurements have transformed our understanding of quantum entanglement, revealing that these ultrafast processes occur on timescales as short as 1.8 attoseconds. According to research from the Vienna University of Technology, these findings challenge previous notions of instantaneous quantum events and highlight the speed of light as a fundamental limit, offering profound implications for fields like quantum computing and particle physics.
