Lecture 6 | Quantum Entanglements, Part 1 (Stanford)

Lecture 6 of Leonard Susskind’s course concentrating on Quantum Entanglements (Part 1, Fall 2006). Recorded October 30, 2006 at Stanford University. This Stanford Continuing Studies course is the first of a three-quarter sequence of classes exploring the “quantum entanglements” in modern theoretical physics. Leonard Susskind is the Felix Bloch Professor of Physics at Stanford University.

    Answer: the coefficients are not normalized.

  • 0101483:

    In the 2 slit electron experiment, with unobserved paths, starting from point 0 on the left then to points +/-1, then to the symmetric midpoint 0 on the screen, say the normalized psi coefficients of the two paths are both equal to 1/sqrt(2). The probability of any given electron being found at the midpoint when either slit is open (but not both) is then 1/2. With both slits open, the probability of finding the electron at the midpoint would then be 2. What is wrong here?
