Tardigrade

In News

• Scientists have identified the first ”quantum entangled” animal in history in a recent study.

About

• Tardigrade: 
  • They are microscopic multicellular organisms known to tolerate extreme physiochemical conditions through a latent state of life known as cryptobiosis.
  • Their proportions are a little bit similar to a bear’s.
• Quantum and biological systems: 
  • These systems are seldom discussed together as they seemingly demand opposing conditions. Life is complex, “hot and wet” whereas quantum objects are small, cold and well controlled.
• Significance: 
  • The coupling between the animal in cryptobiosis and a superconducting quantum bit prepared a highly entangled state between this combined system and another qubit.
  • The tardigrade itself is shown to be entangled with the remaining subsystems.
  • The tardigrade is mostly (frozen) water, and here it acts like a dielectric, shifting the resonance frequency of the one qubit that it sat on.
  • The researchers have claimed that the investigation is perhaps the closest realization combining biological matter and quantum matter available with present-day technology.
