Phase estimation with weak measurement using a white light source
We report results of a high precision phase estimation based on a weak measurement
scheme using a commercial light-emitting diode. The method is based on a measurement of
the imaginary part of the weak value of a polarization operator. The imaginary part of the
weak value appeared due to the measurement interaction itself. The sensitivity of our
method is equivalent to resolving light pulses of the order of a attosecond and it is robust
against chromatic dispersion.
