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…
High-rate qutrit entanglement swapping with photon-number-basis
Kazufumi Tanji, Hikaru Shimizu, Masahiro Takeoka
Entanglement generation between distant nodes is a fundamental process in distributed quantum information processing. Qudits, high-dimensional quantum states, are promising candida…
Passive quantum interconnects: multiplexed remote entanglement generation with cavity-assisted photon scattering
Seigo Kikura, Kazufumi Tanji, Akihisa Goban +1
We propose a time- and wavelength-multiplexed remote atom-atom entanglement generation protocol based on cavity-assisted photon scattering (CAPS). This is designed to achieve a hig…
Quantum state estimation of multi-partite single photon path entanglement via local measurements
Hikaru Shimizu, Joe Yoshimoto, Kazufumi Tanji +5
Multipartite entanglement plays a critical role in various applications of quantum internet. In these applications, the entanglement is usually shared by the distant parties. Exper…
Rate-fidelity trade-off in cavity-based remote entanglement generation
Kazufumi Tanji, Hiroki Takahashi, Wojciech Roga +1
The qubit scalability imposes a paramount challenge in the field of quantum computing. Photonic interconnects between distinct quantum computing modules provide a solution to deal…
