\(Superposition\ States\) VS \(Binary\ Logic\)

the \(\large Fundamental\ Difference\) between \(Binary\ Logic\) and \(Superposition\ States\).

two ideas of the micro world.

Schrodinger's Cat

• Traditional Interpretation: Either live(1) or die(-1),

• Superposition Interpretation of Quantum Mechanics: Superposition of the two quantum states.
  
  $\large f = 50\% \cdot quantum(Left) + 50\% \cdot quantum(Right) $
  
  this equation seems a little bit like the Expectation Equation of Probability Theory.
  
  hypotheses, \(\large quantum(Left) = +1 ; quantum(Rightl)=-1\)
  
  then $\large f = 50\% \cdot (+1) + 50\% \cdot (-1) = 0 $

• (Schrödinger equation, Schrodinger wave equation)

Dirac's Bra & Ket

Superposition Equation of Quantum States

• \(\large Linear\ Combination\ Form(Bra \& Ket) Expression\) of Superposition of Quantum Mechanics:
  
  Using Advanced Linear Algebra to analysis the Quantum Mechanics.
  
  \(\large \begin{array}{lll} \\
  Hypotheses, \text{ There are totally } n\ kinds \text{ of } observed\ outcomes. \\
  \text{ the Superposition state }before\ observation \text{ is }:
  \end{array}\)
  
  \(\large \begin{array}{rll} \\
  SuperPosition_c &=& c_1 \cdot quantum(1) + c_2 \cdot quantum(2) + \cdots + c_n \cdot quantum(n) \\
  \end{array}\)

• Dirac's normalized Vector Form of Quantum Mechanics:

  • each state of superposition can be expressed as a vector \(\large ket\), written as \(\large \ket \phi\)
    
    then the Superposition state can also be written as:
    
    \(\large \begin{array}{rll} \\
    SuperPosition_c &=& c_1 \cdot \ket {E_1}+ c_2 \cdot \ket {E_2{E_1}} + \cdots + c_n \cdot \ket {E_n} \\
    \end{array}\)

  • Inner products of two vectors "bra" $\large \bra \Psi $ and "ket" $\large \ket \Phi $
    
    \(\large \begin{array}{rll} \\
    \bra{\Psi} \ket{\Phi} \\
    \bra \psi \ket \phi \\
    \end{array}\)

  • 泛函空间，矢量vector就是 函数。
    
    那么，假设我们的函数全都是幂函数（或可用Taylor Equation逼近)，形式如下。
    
    则：\(\large \begin{array}{rll} \\
    f &=& c_0 \cdot x^0 + c_1 \cdot x^1 + \cdots + c_n \cdot x^n + \cdots \\
    e^x &=& \frac{1}{1} \cdot x^0 + \frac{1}{1!} \cdot x^1 + \frac{1}{2!} \cdot x^2 + \cdots + \frac{1}{n!} \cdot x^n + \cdots\\
    \end{array}\)

Wave-Particle Duality: Double-slit Experiment

The Maxwell Equations:

• Election, Substances, Particle's Brown Movements
• AZD(Absolute Zero Degree): Each kind of particle has its wave when above AZD.
• The Maxwell Equations:
  
  \(\large \begin{array}{llll} \\
  (\ i\ ) & \bm{\nabla} \cdot \bm{D} &= 4 \pi \rho_{f} \ , & \text{静电荷产生电场}；\\
  (ii\ ) & \bm{\nabla}\cdot \bm{B} &= 0 \ , \text{静磁场磁通量总和为0, 不存在单磁极} \\
  (iii) & \bm{\nabla} \times \bm{E} &= -\frac{\partial\bm{B}}{\partial t}\ , \text{变化的电场感生变化磁场，有函数关系} \\
  (iv\ ) & \bm{\nabla} \times \bm{H} &= \bm{J}_f + \frac{\partial\bm{D}}{\partial t}\ , \text{变化的磁场感生变化电场，有函数关系} \\
  \end{array}\)
