Abstract: A proposal for a physical implementation of a quantum-state discrimination protocol using an ion in a linear trap is studied, where two nonorthogonal quantum states are codified using two electronic states of the ion. In addition, a protocol is given for discriminating superpositions of nonorthogonal entangled states between ions inside widely separated optical cavities. The discrimination protocol is extended to the case of N linearly independent nonorthogonal quantum states lying in a space of $2N\ensuremath{-}1$ dimensions.

Dissonance is required for assisted optimal state discrimination.
TL;DR: It is shown that the optimal case for discriminating between two nonorthogonal states prepared with equal a priori probabilities does not require entanglement but quantum dissonance only.

Probabilistic teleportation without loss of information
Luis Roa,Caspar Groiseau +1 more
TL;DR: In this article, a scheme for teleporting probabilistically an unknown pure state with optimal probability and without losing the information of the state to be teleported was proposed, without having to have copies of the unknown state.

Entanglement swapping via quantum state discrimination
TL;DR: In this article, the combination of the standard protocol with an optimal scheme for quantum state discrimination leads to a reliable protocol for the conclusive probabilistic generation of maximally entangled states.

TL;DR: In this article, the authors proposed schemes to realize two non-standard quantum measurements using cavity quantum electrodynamics (QED), which could be more easily scaled than existing realizations using photons.

Sequential state discrimination with quantum correlation
TL;DR: In this article, the sequential unambiguous state discrimination (SSD) of two states prepared in arbitrary prior probabilities is studied, and compared with three strategies that allow classical communication, and the deviation from equal probabilities contributes to the success in all the tasks considered.

TL;DR: A quantum computer can be implemented with cold ions confined in a linear trap and interacting with laser beams, where decoherence is negligible, and the measurement can be carried out with a high efficiency.

Quantum information and computation
TL;DR: In information processing, as in physics, the classical world view provides an incomplete approximation to an underlying quantum reality that can be harnessed to break codes, create unbreakable codes, and speed up otherwise intractable computations.

Quantum cryptography using any two nonorthogonal states
TL;DR: It is shown that in principle any two nonorthogonal quantum states suffice, and a practical interferometric realization using low-intensity coherent light pulses is described.

Quantum state transfer and entanglement distribution among distant nodes in a quantum network
TL;DR: In this paper, a scheme to utilize photons for ideal quantum transmission between atoms located at spatially separated nodes of a quantum network was proposed, which employs special laser pulses that excite an atom inside an optical cavity at the sending node so that its state is mapped into a time-symmetric photon wave packet that will enter a cavity at receiving node and be absorbed by an atom there with unit probability.
