Catalysis activation magic states fault tolerant architectures
2010/10/29
In many architectures for fault tolerant quantum computing universality is achieved by a combination of Clifford group unitaries and preparation of suitable non-stabilizer states, the so-called magic...
We investigate non-locality distillation using measures of non-locality based on the Elitzur-Popescu-Rohrlich decomposition. For a certain number of copies of a given non-local correlation, we define ...
Novel method of generation of Ca(HCO3)2 and CaCO3 aerosols and first determination of hygroscopic and cloud condensation nuclei activation properties
Ca(HCO3)2 and CaCO3 aerosols hygroscopic and cloud condensation nuclei activation properties
2010/9/21
Atmospheric mineral aerosols contain CaCO3 as a reactive component. A novel method to produce CaCO3 aerosol was developed by spraying Ca(HCO3)2 solution, which was generated from a CaCO3 suspension an...
