Fundamental limits of parameter estimation with heralded optical non-Gaussian states generated from Gaussian resources

Shohei Kiryu, Kazufumi Tanji, Yoshihiro Ueda +2

Non-Gaussian states can exhibit large quantum Fisher information (QFI) in quantum sensing. In optical systems, however, its generation is often probabilistic via the boson-sampling…

Fault-tolerant modular quantum computing with surface codes using single-shot emission-based hardware

Siddhant Singh, Rikiya Kashiwagi, Kazufumi Tanji +4

Fault-tolerant modular quantum computing requires stabilizer measurements across the modules in a quantum network. For this, entangled states of high quality and rate must be distr…
