Quantum Cryptography, Day 1: Qubits, Kets, and Bras

Overview

The edX course in quantum cryptography is an interdisciplinary course developed in collaboration between QuTech at Delft University of Technology and the California Institute of Technology. The instructors are Stephanie Wehner of the QuTech Research Center, Delft University of Technology, Netherlands, and Thomas Vidick, Computing and Mathematical Sciences Department at the California Institute of Technology, Pasadena, California, USA.

Classical bits

0 \rightarrow \left|0\right>=\begin{pmatrix}1\\0\end{pmatrix}

1 \rightarrow \left|1\right>=\begin{pmatrix}0\\1\end{pmatrix}

Qubits

\left|\psi\right>=\begin{pmatrix}\alpha\\\beta\end{pmatrix}=\left.\alpha | 0 \right>+\left.\beta |1 \right>

Mr. Trump’s Space Force vs Mr. Reagan’s Star Wars

Mr. Trump’s Space Force and Mr. Reagan’s “Star Wars” are actually somewhat similar in nature. Russia has been developing intercontinental ballistic missiles since the 1950s, anti-satellite missiles since the 1960s, and by the 1970s the Russians also had satellites in space that could also function as satellite killers [1]. When the Cold War ended around 1990, the Russians let the satellite killer capabilities atrophy, and US operated its satellites without any threats to its guaranteed space superiority, for the first time ever. From that point until China’s anti-satellite missile test in 2007, the US had no fear of China or Russia attacking its satellites [2]. Since that time, both Russia and China have increased anti-satellite capabilities to the point where it forced the US to think about creating a Space Force.
