High purity single photons entangled with an atomic qubit.

Trapped atomic ions are an ideal candidate for quantum network nodes, with long-lived identical qubit memories that can be locally entangled through their Coulomb interaction and remotely entangled through photonic channels. The integrity of this photonic interface is generally reliant on the purity of single photons produced by the quantum memory. Here, we demonstrate a single-photon source for quantum networking based on a trapped Ba ion with a single photon purity of (0)=(8.

Multispecies Trapped-Ion Node for Quantum Networking.

Trapped atomic ions are a leading platform for quantum information networks, with long-lived identical qubit memories that can be locally entangled through their Coulomb interaction and remotely entangled through photonic channels. However, performing both local and remote operations in a single node of a quantum network requires extreme isolation between spectator qubit memories and qubits associated with the photonic interface. We achieve this isolation by cotrapping ^{171}Yb^{+} and ^{138}Ba^{+} qubits.

[Vulvovaginitis. Occurrence and importance of mixed and unclassifiable pictures].

Objective: To evaluate the occurrence of mixed and unclassifiable vulvovaginitis (i.e. those, which fulfill the diagnostic criteria of several diagnostic units or no diagnostic unit) in symptomatic and asymptomatic women.

[The effect of diazepam and flumazenil on pulsatile secretion of prolactin and LH in women].

The authors examined the effect of diazepam and flumazenil on prolactin and LH secretion in women. The experiment lasted 12 hours during which specimens of venous blood were collected for assessment of LH and prolactin after 10-minute intervals. After 5 hours to a group of 8 women (4 in the luteal and 4 in the follicular stage of the cycle) flumazenil was administered--3 x 10 mg i.
