What is quantum supremacy and why is it significant?
-Quantum supremacy is the point at which quantum computers can perform certain tasks faster than the world's most powerful supercomputers. It's significant because it marks a milestone in demonstrating the superior processing capabilities of quantum computers.
What was Google's claim regarding quantum supremacy in 2019?
-Google claimed to have achieved quantum supremacy using a 53 qubit processor named Sycamore, which performed a computation in 200 seconds that would take the world's fastest supercomputer around 10,000 years.
What was IBM's contention to Google's quantum supremacy claim?
-IBM argued that one of its supercomputer networks at the Oak Ridge National Laboratories could theoretically solve the same problem in a matter of days, not the 10,000 years claimed by Google.
How does the funding landscape for quantum computing compare to that of artificial intelligence?
-While artificial intelligence attracted about $9.3 billion in venture capital funding in 2018, quantum computing received significantly less, with companies receiving at least $450 million in private funding over the same period. However, the growth in quantum computing funding is happening quickly.
What are the technical challenges in developing practical quantum computers?
-Quantum computers require extremely controlled environments to operate, with sensitivity to nearby temperatures and electromagnetic waves. They also need to be kept at temperatures colder than interstellar space, close to absolute zero.
