Abstract

Here, we present an experimental study of erasure for a memory encoded in an asymmetric double-well potential. Using a feedback trap, we find that the average work to erase can be less than \(kT\ln 2\).

Notes

  1. 1.

    Such a change is done with a single harmonic trap and should not be confused with the work needed to erase memory (Landauer limit).
