    • It is interesting to note that other groups have reported many measurements of retarded van der Waals forces between dielectrics in liquids. The precision of these experiments appears to be less accurate than the one obtained with metals in vacuum. See for example Ref. [6], and L. Suresh and J.Y. Waltz, J. Colloid Interface Sci. 196, 177 (1997)

    • pz. This effect is usually kept into account in modern experiments with a procedure that requires the sphere to be brought into contact with the plate. This procedure can damage the sensor and the two metallic surfaces, a relevant drawback in our experiments, where many measurements had to be repeated with the same device and where surface damages can significantly alter the measurement. However, it is possible to estimate that the separation between the sphere and the plate varies by less than 1 nm for a plate rotation of 5 μrad induced by the Casimir force. This affects any discrepancy between theory and experiment by ≃1% and is therefore negligible in the context of this paper. This effect of course also affects the calibration of the set up with an electrostatic force. One can show that keeping it into account would affect the data in the opposite direction with respect to the above correction.

    • We have actually used a slightly different set-up. The experiment, however, was carried out by using the data acquisition technique described in Section 2.

    • For the sake of simplicity, we have used the Drüde model for the dielectric function of gold (see Ref. [10]).

    • 2 (≃12 nm) is slightly smaller than what was obtained with the optical profiler (≃15 nm) over a larger area. Therefore, ignoring topological details not accessible to optical profiler measurements does not affect the conclusions of our experiment.

    • The sign of the torque expected in the case of a quartz disk is opposite to the one obtained with calcite. We refer the reader to [41] for further details.

    • It can be shown that Brownian motion should not play an important role in the rotation. We refer the reader to [41] for a detailed analysis of this topic.
