Phy.org  March 17, 2023 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 […]
