Quantum supremacy refers to quantum computers being able to solve a problem that a classical computer cannot. In the research paper, Google used a 53-qubit processor to generate a sequence of millions of numbers. Though these numbers appeared randomly generated, they conform to an algorithm generated by Google. A classical supercomputer checked some of these values and they were correct. Google’s quantum computer, named Sycamore, claimed ‘supremacy’ because it reportedly did the task in 200 seconds that would have apparently taken a supercomputer 10,000 years to complete.
Benefits:
- Quantum computers will change the landscape of data security. Even though quantum computers would be able to crack many of today’s encryption techniques, predictions are that they would create hack-proof replacements.
- Quantum computers are great for solving optimisation problems from figuring out the best way to schedule flights at an airport
- Quantum computers will make it possible to process the amount of data we’re generating in the age of big data.
- Rather than use more electricity, quantum computers will reduce power consumption anywhere from 100 up to 1000 times because quantum computers use quantum tunnelling.Quantum computers are very fragile. Any kind of vibration impacts the atoms and causes decoherence.
