Harvard scientists have announced that they can accelerate the development of supercomputers. They also proved the existence of a new substance called quantum spin fluid that could help treat diseases like Alzheimer's. It is thought that the quantum spin fluid will play an active role in this new situation. Quantum spin fluid has magnetic properties as well as creating long-range quantum entanglement. In other words, according to the predictions of scientists, we can say that Alzheimer's Disease, which is one of the most serious medical problems of our age, can bring New Hope.
In achieving this new state, laser and quantum computing were used to manipulate the geometry and interactions of atoms. This new state of matter can now be used to develop popular quantum technologies such as quantum computers.
According to Harvard scientists, as a result of this discovery, scientific research would accelerate and a substance that could lead to the treatment of diseases such as Alzheimer's was found. This discovery by the researchers came nearly 50 years after their initial estimate.
The particles of the quantum spin fluid are widely spaced apart, but remain bound together due to the magnetic properties of their atoms.
Although the concept of matter and the experiments used to prove it are very complex, it is thought to be an extremely useful study in the end.
This is because the quantum spin fluid can significantly accelerate the development of new quantum computers.
These machines, whose development is still in its infancy, can be used to solve problems much faster than current computers.
Scientists predict that they will make a big difference to diseases that are currently impossible to treat effectively, eventually producing cures, including Alzheimer's.
Quantum spin fluid was first predicted by physicist Philip W. Anderson in 1973, but the situation was never observed in experiments.
But rather than trying to prove its existence on paper, the Harvard team used an experimental approach to recreate it in the lab.
Giulia Semeghini, a postdoctoral researcher at the Max Planck-Harvard Center for Quantum Optics Research and lead author of the study, said in a statement:
“A few theorists at Harvard have come up with an idea of how to actually create this phase, which will basically replace the solid systems environment.
Quantum spin fluid has magnetic properties due to the entanglement of atoms and the constant change of material.
Properties of Quantum Spin Fluid
Quantum spin fluid has special properties that produce long-range quantum entanglement, as we mentioned earlier.
This means that its particles are connected even though they are separated by distance. Since the material is designed like a cage, it also has magnetic properties.
Harvard Physicists used the simulator to build the lattice model, then placed the atoms in the design and observed their interaction and entanglement.
Standard quantum computers have individual quantum bits, or "qubits," (particles that can encode information), Semeghini said, and these are "very fragile to external entanglement."
However, Semeghini said that with quantum spin fluids, a 'topological qubit' can be created that stores information in the topology of a system – in the form – as opposed to a standard qubit, which stores information in the state of a single object. Thanks to this obtained information, it was very difficult to break the topology and it was a serious advantage.
Physics professor Mikhail Lukin, senior author of the study and co-director of the Harvard Quantum Initiative, said that the group only created a "baby version" of the topological qubit, and that this is far from useful for real application, but the finding was nonetheless. He said it was exciting.
“It's very basic physics that we're doing though,” Lukin said.
“But the fact that we can create these kinds of situations and really play with them, tinker with them, actually kind of talk to them and see how they react – that's what's exciting.” There is also an explanation.
