1 / 5

Quantum entanglement of photon pairs can arise from a process similar to that in OPOs. What distinguishes entangled photon generation in spontaneous parametric down-conversion (SPDC) from standard OPO operation?

OPOs operate at cryogenic temperatures, SPDC doesn’t

OPOs violate conservation of energy, SPDC doesn’t

SPDC emits entangled photons randomly without cavity feedback

SPDC requires continuous-wave pumping only

2 / 5

Which principle says it’s impossible to know both the exact position and momentum of a particle at the same time?

Schrödinger’s Cat

Pauli Exclusion Principle

Heisenberg Uncertainty Principle

Planck’s Constant

3 / 5

Which Nobel Prize-winning experiment confirmed the violation of Bell’s inequalities, supporting quantum entanglement over classical realism?

Aspect experiment

Davisson-Germer experiment

Stern-Gerlach experiment

Michelson-Morley experiment

4 / 5

In quantum optics, what is “squeezed light”?

Light with reduced wavelength

Light produced at cryogenic temperatures

Light generated in a fiber laser

Light with less noise in one quadrature and more in the other

5 / 5

Why are ultrafast OPOs especially valuable in quantum control experiments?

They generate X-rays suitable for entanglement experiments

They provide non-classical light without photon correlations

They enable coherent control of quantum states with high time resolution

They can cool atoms to near absolute zero
