UPDATE: Donald Trump Takes Office as the 47th US President

Supreme Court Lets Trump Fire Consumer Product Safety Regulators​

The ruling allowed President Trump to fire the three Democratic members of the Consumer Product Safety Commission, a five-member group that monitors the safety of items like toys, cribs and electronics.

In a jaw-dropping leap forward, China’s 76-qubit quantum computer "Jiuzhang" has achieved something classical supercomputers could only dream of solving a complex mathematical problem in just four minutes that would take billions of years using today’s fastest traditional systems. This milestone doesn’t just represent speed. It’s a clear signal that quantum supremacy has arrived.



What makes Jiuzhang so different is its design. Instead of using silicon chips and wires, it’s built from lasers, mirrors, and photon detectors. The system uses Gaussian boson sampling, a method that involves detecting and counting photons with extreme accuracy. While even the best classical computers can simulate only five photons, Jiuzhang successfully handled 76 a quantum leap that shattered the limits of computational physics.



This is not just a headline-grabbing stunt. The implications are profound. Quantum computers like Jiuzhang could soon revolutionize everything from quantum chemistry to logistics, optimization, cryptography, and even the birth of a quantum internet. As quantum systems grow more stable and scalable, our entire digital world may be rebuilt from the ground up using light instead of code.
