Entanglement is a key part of quantum computing Bartlomiej K. Wroblewski/Alamy
While scientists generally try to find sensible explanations for weird phenomena, quantum entanglement has them tied in knots.
This link between subatomic particles, in which they appear to instantly influence one another no matter how far apart, defies our understanding of space and time. It famously confounded Albert Einstein, who dubbed it “spooky action at a distance”. And it continues to be a source of mystery today. “These quantum correlations seem to appear somehow from outside space-time, in the sense that there is no story in space and time that explains them,” says …
