What this part means

The expressions on both sides represent the same quantity under the stated assumptions.

Its job in the formula

The equals sign connects the complete expression on the left with the complete expression on the right. Both sides must have compatible units.

The passage around this formula

2015 closed both, three times over. Hensen and colleagues at Delft entangled electron spins in diamond, 1.3 kilometres apart, and measured S = 2.42 ±\pm 0.20 against the bound of 2, with detection efficient enough and separation wide enough to close both loopholes together [ 4 ] . Giustina and colleagues in Vienna, using entangled photons and high-efficiency detectors, reported a violation whose probability under local realism was no greater than 3.74 ×\times 10^{-31} [ 5 ] ; Shalm and colleagues at NIST, independently, reported p-values as low as 5.9 ×\times 10^{-9} [ 6 ] . Between the three, no known loophole remained.
