While network of bosons has mostly been implemented in optical systems using photons, alternative realizations addressing major limitations in photonic systems such as photon loss have been explored recently.
Quantized excitations of vibrational modes of trapped ions are a promising candidate to realize such bosonic networks. An international team of researchers China, Italy, UK) has demonstrated a minimal-loss programmable phononic network in which any phononic state could be deterministically prepared and detected. They created networks with up to four collective vibrational modes, which could be extended to reveal quantum advantage. They benchmarked the performance of the network with fixed total phonon number. The reconstruction fidelities for both single- and two-phonon states were high. According to the researchers their findings demonstrates a clear pathway to scale up a phononic network for quantum information processing beyond the limitations of classical and photonic systems… read more.
