Entanglement and teleportation between polarization and wave-like encodings of an optical qubit
Demid V. Sychev, Alexander E. Ulanov, Anastasia A. Pushkina +3
Light is an irreplaceable means of communication among various quantum information processing and storage devices. Due to their different physical nature, some of these devices cou…
Two-level masers as heat-to-work converters
A. Ghosh, D. Gelbwaser-Klimovsky, W. Niedenzu +4
Heat engines, which cyclically transform heat into work, are ubiquitous in technology. Lasers and masers, which generate a coherent electromagnetic field, may be viewed as heat eng…
Holevo Bound of Entropic Uncertainty in Schwarzschild Spacetime
Jin-Long Huang, Wen-Cong Gan, Yunlong Xiao +2
For a pair of incompatible quantum measurements, the total uncertainty can be bounded by a state-independent constant. However, such a bound can be violated if the quantum system i…
Quantum repeaters with individual rare-earth ions at telecommunication wavelengths
F. Kimiaee Asadi, N. Lauk, S. Wein +3
We present a quantum repeater scheme that is based on individual erbium and europium ions. Erbium ions are attractive because they emit photons at telecommunication wavelength, whi…
Massive outflows associated with ATLASGAL clumps
Aiyuan Yang, Mark Thompson, James Urquhart +1
We have undertaken the largest survey for outflows within the Galactic Plane using simultaneously observed 13CO and C18O data. 325 out of a total of 919 ATLASGAL clumps have data s…
New Distances to Four Supernova Remnants
S. Ranasinghe, D. A. Leahy, Wenwu Tian
Distances are found for four supernova remnants without previous distance measurements. H I spectra and H I channel maps are used to determine the maximum velocity of H I absorptio…
