Harnessing spin-qubit decoherence to probe strongly-interacting quantum systems

Harnessing spin-qubit decoherence to probe strongly-interacting quantum systems

Extracting information from quantum many-body systems remains a key challenge in quantum technologies due to experimental limitations. In this work, we employ a single spin qubit to probe a strongly interacting system, creating an environment conducive to qubit decoherence. By focusing on the XXZ spin chain, we observe diverse dynamics …
