Three-party d-level quantum secret sharing protocol
Dong Pyo Chi, Jeong Woon Choi, Jeong San Kim +2
We develop a three-party quantum secret sharing protocol based on arbitrary dimensional quantum states. In contrast to the previous quantum secret sharing protocols, the sender can…
Entanglement of subspaces in terms of entanglement of superpositions
Gilad Gour, Aidan Roy
We investigate upper and lower bounds on the entropy of entanglement of a superposition of bipartite states as a function of the individual states in the superposition. In particul…
Super- and subradiant emission of two-level systems in the near-Dicke limit
Peter G. Brooke, Karl-Peter Marzlin, James D. Cresser +1
We analyze the stability of super- and subradiant states in a system of identical two-level atoms in the near-Dicke limit, i.e., when the atoms are very close to each other compare…
Entanglement of group-II-like atoms with fast measurement for quantum information processing
R. Stock, N. S. Babcock, M. G. Raizen +1
We construct a scheme for the preparation, pairwise entanglement via exchange interaction, manipulation, and measurement of individual group-II-like neutral atoms (Yb, Sr, etc.). G…
The resource theory of quantum reference frames: manipulations and monotones
Gilad Gour, Robert W. Spekkens
Every restriction on quantum operations defines a resource theory, determining how quantum states that cannot be prepared under the restriction may be manipulated and used to circu…
SU(1,1) symmetry of multimode squeezed states
Zahra Shaterzadeh-Yazdi, Peter S. Turner, Barry C. Sanders
We show that a class of multimode optical transformations that employ linear optics plus two-mode squeezing can be expressed as SU(1,1) operators. These operations are relevant to…
