We first review the mathematical physics of quantum decoherence in generic single-qubit devices, including environmental interactions. Next, we formulate the persistence probability for a qubit device as the probability of measuring the qubits in their unperturbed state without the decoherence arising from environmental interactions. A decoherence time can be obtained from the persistence probability. Drawing on recent work of Garg, and also Palma, Suomine, and Ekert, we apply the persistence probability formalism to a generic single-qubit device coupled to a thermal environment, and also apply it to a trapped-ion quantum register coupled to its ion vibrational modes.
