Equipe japonesa desenvolve método para detectar estados W quânticos

Pesquisadores das universidades de Kyoto e Hiroshima criaram uma nova técnica para identificar estados W, uma forma complexa de emaranhamento quântico. O avanço pode apoiar o progresso na computação e comunicação quântica.

Uma equipe liderada por Shigeki Takeuchi demonstrou o método usando três fótons em um circuito óptico estável. O dispositivo realiza uma transformação de Fourier quântica baseada na simetria de deslocamento cíclico dos estados W. Ele distingue diferentes estados W de três fótons em uma única medição, sem a necessidade de ajustes extensivos durante a operação.
