Un equipo japonés desarrolla un método para detectar estados W cuánticos

Investigadores de la Universidad de Kioto y la Universidad de Hiroshima han creado una nueva técnica para identificar estados W, una forma compleja de entrelazamiento cuántico. El avance podría respaldar el progreso en la computación y comunicación cuánticas.

Un equipo dirigido por Shigeki Takeuchi demostró el método utilizando tres fotones en un circuito óptico estable. El dispositivo realiza una transformación cuántica de Fourier basada en la simetría de desplazamiento cíclico de los estados W. Este distingue diferentes estados W de tres fotones en una única medición sin necesidad de realizar ajustes extensos durante su funcionamiento.
