Rather than producing a photon on one side and a vacuum on the other, the shutter generates something far more strange and complex: a superposition of states containing infinitely many photons simultaneously.

This happens because, in quantum mechanics, empty space isn't truly empty—in reality, it seethes with fluctuations in the electromagnetic field. By rapidly switching the shutter, the team found that these fluctuations are disturbed—and in doing so, they spontaneously create new photons. Crucially though, if you were to look only at the region immediately either side of where the shutter operated, the state would appear deceptively normal: indistinguishable from a single photon on one side, and a simple vacuum on the other.

Quantum entanglement is one of the strangest features of quantum mechanics. When two particles are entangled, a measurement of one instantly affects the other. Scientists had demonstrated this before in photons (packets of light) and in the internal spin states of atoms but never in the motion of particles with mass. This is important because atoms have mass, and mass responds to gravity; photons don't. Momentum-entangled atoms could one day power quantum sensors precise enough to detect space-time ripples called gravitational waves or to map Earth's interior.

Thanks for not leaving this up to conjecture.
