Por más de un cuarto de siglo, un problema aparentemente sencillo resistió todos los intentos de la física cuántica: medir con precisión un tipo específico de entrelazamiento llamado estado W. Investigadores de las universidades de Kioto y Hiroshima lograron finalmente lo que parecía imposible, diseñando un circuito fotónico que convierte la estructura oculta del entrelazamiento en algo medible con una sola operación. Este avance no solo cierra una deuda pendiente con la teoría, sino que abre un camino más firme hacia redes de comunicación cuántica que algún día podrían operar fuera de los lab
