# s-phys: "entanglement entropy of a qubit", the begin ...

<< All systems are fundamentally quantum systems (..) but the means of describing in a quantum sense the chaotic behavior of, say, air molecules in an evacuated room, remains limited >>

<< To investigate, [AA] devised an experiment using three quantum bits, the basic computational units of the quantum computer >>

<< By manipulating these qubits with electronic pulses, [AA] caused them to interact, rotate and evolve in the quantum analog of a highly sensitive classical [chaotic] system >>

<< The result is a map of entanglement entropy of a qubit that, over time, comes to strongly resemble that of classical dynamics — the regions of entanglement in the quantum map resemble the regions of chaos on the classical map >>

# e-sec: brainjacking in medical implants

<< Here  are  some  real  examples  of  what  can  be  achieved  if  you  have  access  to  somebody’s  DBS [Deep Brain Stimulation] electrodes.  You  can  induce  mania,  hypersexuality,  and  even  pathological  gambling.  You  can modify  emotions.  Patients  undergoing  DBS  therapy  have  sometimes  experienced  pathological crying  and  inappropriate  laughter,  "likely  due  to  off-target  stimulation,"  says  the  paper.  Strong sensations  of  fear  and  panic  have  also  been  observed. >>

# n-trade: three dates to worry about, by Sandy

<< The man who accurately predicted four market crashes to the exact date each time has told Business Insider about three more dates to worry about. >>

<< He now warns that the following dates spell trouble for the Dow Jones in the US that could spread to other markets.

1. Between August 26 and August 30, 2016.
2. September 26, 2016.
3. October 20, 2016. >>

<< Technical analysts use historical charts to spot patterns in the markets.They cannot tell you what event will move the markets.  They can only tell you when a shift is likely to happen. >>
