... FIG. 3 (color online). Proposed setup for the implementation of DIQKD based on a heralded qubit amplifier. The entangledphoton source is located close to Alice’s location. Each of Alice’s and Bob’s black boxes includes a measurement apparatus. Furthermore, Bob’s box contains the qubit amplifier whic ...

Path integral Monte Carlo study of the interacting quantum double-well... Quantum phase transition and phase diagram
... PIMC simulation and has a maximum at V0 = 1. This behavior of Jc can be understood as follows: In the region V0 Ⰷ 1 the potential has two deep minima separated by a barrier V0 giving rise to a nearly degenerated ground-state doublet that is well separated from the rest of the spectrum, as shown in t ...

Memory-built-in quantum teleportation with photonic and atomic qubits
... With emphasis we note that, because the two-photon events from the weak coherent pulses contribute a significant amount of spurious twofold BSM coincidences—which herald nothing but the arrival of two source photons and cannot be distinguished from the true BSM results—a twofold BSM click can only w ...

... of physically interesting operators for the given quantum state. Our aim here is to build an adequate representation space for bipartite systems. We are guided by the relation of the standard Bloch sphere to a geometric object called the Hopf fibration of the S3 hypersphere (identified to the spin 1 ...
