- Abstract: We implement a five-qubit protocol in IBM quantum processors to get
entanglement dynamics in a two qubit system in the presence of an environment.
Specifically, two qubits represent the main system, another two qubits the
environment, and an additional qubit is used as an auxiliary qubit to perform
the quantum entanglement estimation. We focus on measuring, in this
superconducting quantum processor, the sudden death and sudden birth of
entanglement. We obtain the quantum entanglement evolution of the main system
qubits and the environment qubits as the average of $N=10$ independent
experiments in the same quantum device, observing that the noisy nature of
current quantum processors produce a shift on times signaling sudden death o
sudden birth of entanglement. This work takes relevance showing the usefulness
of current noisy quantum devices to test fundamental concepts in quantum
information.
