Quantum uncertainty

Outcome probabilities:

Prob(+ħ/2) = 1

Prob(–ħ/2) = 0

Prob(+ħ) = 1

Prob(0) = 0

Prob(-ħ) = 0

Certain of outcome +ħ/2 prior to measurement

ΔS_θ = 0

Change quantum uncertainty: SGA angle θ = 0°

Instrumental imperfections

Perfect apparatus and detector

Spread (standard deviation σ) of each spot after

many measurements: 0

Change instrumental imperfections: σ = 0

Statistical uncertainty

No statistical uncertainty: infinite counts

1.000 of total counts in +ħ/2 spot (expected: 1.000)

0.000 of total counts in –ħ/2 spot (expected: 0.000)

1.000 of total counts in +ħ spot (expected: 1.000)

0.000 of total counts in 0 spot (expected: 0.000)

0.000 of total counts in –ħ spot (expected: 0.000)

Change statistical uncertainty: Number of counts N = ∞
