The new photonic computer Jiuzhang 4.0 pushes photons through a network of microchannels and uses photometry—precise counting of light flashes—to record the final pattern. This pattern is beyond any ordinary computer: it would require sifting through more possibilities than atoms in the universe. Th

In the famous thought experiment between Einstein and Bohr, the atomic slit always trembles due to quantum noise. This noise, like an unceasing whisper, smears the wave pattern. Now, physicists have learned to squeeze this whisper: to hush the part that gives away the particle's path. Fringe contras
