Google achieves Quantum Supremacy but what is it?
Google calls the new chip, which forms the basis of such capability, Sycamore.
Google has announced that it has achieved Quantum Supremacy -- the capability to do calculations that go beyond the scope of classical computers.
This comes a month after a leaked version of the report appeared on a NASA website. But it was later removed.
Google calls the new chip, which forms the basis of such capability, Sycamore. The company claims that it can perform a computation, which would take the world’s fastest computer 10,000 years, in 200 seconds.
Difference between classical and quantum computers:
Computers do calculations based on binary numbers 0 and 1, which are called bits. A bit can be stored in either of two possible distinct states represented by a charge or a voltage.
But in Quantum computers these bits are represented by subatomic particles. Special properties of such particles like superposition and quantum entanglement increase the possible number of states the particles can exist in to more than two. This, in turn, increases the power of the computer by an exponential level.
So the quantum computers will be faster, more diverse and much more efficient.
What can it be used for?
Google in a blog post says that Quantum Supremacy will help in areas such as designing better batteries, figuring out what molecules might make effective medicines or minimizing emissions from the creation of fertilizer.
It would also be helpful in advancing technologies like machine learning. Quantum computers can be useful in areas such as AI, bio-chemistry, quantum physics, space exploration and more.
IBM, one of the companies running in the quantum computing race, has dismissed the announcement, saying that Google overstated it.
