Heralded Single-Magnon Quantum Memory for Photon Polarization States
... magnon corresponding to the input-field polarization is stored with high fidelity and can be retrieved with good efficiency. The single-photon nature of the retrieved field is confirmed by a conditional autocorrelation measurement indicating sub-Poissonian statistics [g2 ¼ 0:24ð5Þ < 1]. The heraldin ...

Quantum Theory: a Pragmatist Approach
... account of probability! Of course, he would insist that different persons may, and often do, hold different beliefs, which makes probability personalist—varying from person to person—and to that extent subjective. On other “subjectivist” views, an agent’s degrees of belief count as probabilities onl ...

Ultrafast geometric control of a single qubit using chirped pulses
... vector turns about the effective field vector Ω1 (about the x-axis); it stays in the y, z-plane all the time and points in the −z (z)-direction at the end of the pulse. Due to the second π-pulse, the population is transferred back to the initial state |0i (|1i); therefore the Bloch vector returns to ...
