Packet 10: Bonus 21

These states follow a Poisson distribution in the energy eigenbasis and can be visualized as minimum volume spheres in phase space. For 10 points each:
[10m] Name these eigenstates of the annihilation operator. They can be created by applying a displacement operator to the vacuum.
ANSWER: coherent states [or Glauber states]
[10h] A superposition of two coherent states with opposite eigenvalues is an example of one of these quantum states. These states are superpositions of diametrically opposed macroscopic outcomes.
ANSWER: cat states [or Schrödinger cat state]
[10e] Coherent states achieve the minimum prescribed by this eponymous statement, which sets a lower limit on the product of the standard deviations of position and momentum.
ANSWER: Heisenberg uncertainty principle [or Heisenberg uncertainty principle]
