13 Mar 2017 | Abstract: | Fast and reliable reset of a qubit is a key prerequisite for any quantum
technology. For real world open quantum systems undergoing non-Markovian
dynamics, reset implies both purification and erasure of correlations between
qubit and environment. Here, we derive optimal reset protocols using a
combination of geometric and numerical control theory. For factorizing initial
states, we find a lower limit for the entropy reduction of the qubit and a
speed limit. The time-optimal solution is determined by the maximum coupling
strength. Initial correlations, remarkably, allow for faster reset and smaller
errors. | Source: | arXiv, 1703.4483 | Services: | Forum | Review | PDF | Favorites |
