Scientists have claimed to have entangled tardigrades – known for their ability to survive extreme environments – with a qubit, using the rules of quantum mechanics. However, some physicists are sceptical of the experiment's results. Without the tardigrade, the entanglement can still be measured, leading to doubts about whether entanglement actually occurred. In any case, the study sheds new light on the hardiness of tardigrades, which can reportedly survive even the vacuum of space.
Sure, here are the key facts extracted from the text:
1. Scientists claimed to have entangled three tardigrades after freezing them to almost absolute zero, using the rules of quantum mechanics.
2. Tardigrades, also known as water bears, are known for their ability to survive extreme conditions such as low temperatures, radiation, and high pressures.
3. Tardigrades can expel more than 95% of the water in their bodies, curling up into a dehydrated state to survive harsh conditions.
4. Researchers attempted to create quantum entanglement by cooling tardigrades and placing them between capacitor plates of a superconductor circuit.
5. Some physicists are skeptical about whether the tardigrades actually entered a quantum entangled state, as the experiment's results have been questioned.
6. Quantum entanglement is a phenomenon where two particles can be linked in such a way that a measurement on one particle affects the other, regardless of their distance.
7. Critics argue that the experiment might not demonstrate true quantum entanglement, but rather a classical effect due to the tardigrade's presence.
8. The scientific paper describing this experiment has not yet been peer-reviewed, and early responses from the scientific community have been critical.
9. One tardigrade from the experiment was successfully revived more than 17 days after being frozen to extreme cold.
10. The debate continues regarding whether this experiment truly demonstrates quantum entanglement or not.
