T violation and the unidirectionality of time
Joan A. Vaccaro
An increasing number of experiments at the Belle, BNL, CERN, DAΦNE and SLAC accelerators are confirming the violation of time reversal invariance (T). The violation signifies a fun…
Optimal reference states for maximum accessible entanglement under the local particle number superselection rule
G. A. White, J. A. Vaccaro, H. M. Wiseman
Global conservation laws imply superselection rules (SSR) which restrict the operations that are possible on any given state. Imposing the additional constraint of local operations…
Quantum protocols for anonymous voting and surveying
J. A. Vaccaro, Joseph Spring, Anthony Chefles
We describe quantum protocols for voting and surveying. A key feature of our schemes is the use of entangled states to ensure that the votes are anonymous and to allow the votes to…
Tradeoff between extractable mechanical work, accessible entanglement, and ability to act as a reference system, under arbitrary superselection rules
J. A. Vaccaro, F. Anselmi, H. M. Wiseman +1
Superselection rules (SSRs) limit the mechanical and quantum processing resources represented by quantum states. However SSRs can be violated using reference systems to break the u…
Remote control of restricted sets of operations: Teleportation of Angles
S. F. Huelga, M. B. Plenio, J. A. Vaccaro
We study the remote implementation of a unitary transformation on a qubit. We show the existence of non-trivial protocols (i.e., using less resources than bidirectional state telep…
A class of symmetric controlled quantum operations
John A. Vaccaro, O. Steuernagel, S. F. Huelga
Certain quantum gates, such as the controlled-NOT gate, are symmetric in terms of the operation of the control system upon the target system and vice versa. However, no operational…
