Abstract:
We demonstrate a decoherence-free quantum memory of one qubit. By encoding the qubit into the decoherence-free subspace DFS of a pair of trapped 9Be ions, we protect the qubit from environment-induced dephasing that limits the storage time of a qubit composed of a single ion. We measured the storage time under ambient conditions and under interaction with an engineered noisy environment and observed that encoding into the DFS increases the storage time by up to an order of magnitude. The encoding reversibly transfers an arbitrary qubit stored in a single ion to the DFS of two ions.
