ANALIZAMOS LA POSIBILIDAD DE MEDIR EL ESTADO CUÁNTICO DE UN ESPEJO MÓVIL USANDO SU INTERACCIÓN CON UN CAMPO CUANTIZADO. MOSTRAMOS QUE MIDIENDO LAS CUADRATURAS DEL CAMPO PERMITE LA RECONSTRUCCIÓN DE LA FUNCIÓN CARACTERÍSTICA CORRESPONDIENTE AL ESPEJO MÓVIL.AbstractWE ANALYZE THE POSSIBILITY OF MEASURING THE STATE OF A MOVABLE MIRROR BY USING ITS INTERACTION WITH A QUANTUM FIELD. WE SHOW THAT MEASURING THE FIELD QUADRATURES ALLOWS US TO RECONSTRUCT THE CHARACTERISTIC FUNCTION CORRESPONDING TO THE MIRROR STATE.WE ANALYZE THE POSSIBILITY OF MEASURING THE STATE OF A MOVABLE MIRROR BY USING ITS INTERACTION WITH A QUANTUM FIELD.
