Modern quantum tools for bosonic systems

Presenting Author: Victor Albert , NIST

I overview ongoing efforts to extend state-of-the-art discrete-variable (DV) tomographic, error-correction, and cryptographic protocols to bosonic systems, including: (1) a theory of appropriately defined CV state designs, and their applications to design-based CV shadow tomography; (2) a cryptographic protocol utilizing squeezed states whose proof of security is based on a CV extension of DV monogamy-of-entanglement games; (3) sample efficiency of homodyne and photon-number-resolving tomography obtained via recasting said protocols in terms of shadow tomography; and (4) a unified decoding framework for concatenated DV and CV error-correcting codes.
