How to detect qubit-environment entanglement generated during qubit dephasing
Katarzyna Roszak, Damian Kwiatkowski, Łukasz Cywiński
We propose a straightforward experimental protocol to test whether qubit-environment entanglement is generated during pure dephasing of a qubit. The protocol is implemented using o…

Decoherence of two entangled spin qubits coupled to an interacting sparse nuclear spin bath: application to nitrogen vacancy centers
Damian Kwiatkowski, Łukasz Cywiński
We consider pure dephasing of Bell states of electron spin qubits interacting with a sparse bath of nuclear spins. Using the newly developed two-qubit generalization of cluster cor…
