Coherent-state optical qudit cluster state generation and teleportation via homodyne detection
Jaewan Kim, Juhui Lee, Se-Wan Ji +3
Defining a computational basis of pseudo-number states, we interpret a coherent state of large amplitude, , as a qudit --- a -level quantum system --- in a s…

Superactivation, unlockability, and secrecy distribution of bound information
Giuseppe Prettico, Joonwoo Bae
Bound information, a cryptographic classical analogue of bound entanglement, is defined as classical secret correlations from which no secret key can be extracted. Its existence wa…

Loophole-free Bell test for continuous variables via wave and particle correlations
Se-Wan Ji, Jaewan Kim, Hai-Woong Lee +2
We derive two classes of multi-mode Bell inequalities under local realistic assumptions, which are violated only by the entangled states negative under partial transposition in acc…
