Google's Sycamore quantum computer was the first to demonstrate quantum supremacy – solving calculations that would be unfeasible on a classical computer – but now ordinary machines have pulled ahead again
In 2019, Google claimed that its Sycamore quantum computer could perform calculations that would take even the world’s most powerful classical supercomputer 10,000 years to complete – but now it seems that a non-quantum computer crunches the numbers several times faster than Google’s machine, and uses less energy doing so.
Quantum computers have the potential to carry out some kinds of calculations vastly more quickly than classical computers, but are still in their infancy. Google announced in 2019 that Sycamore had achieved “quantum supremacy” – the point at which a quantum computer can…

In quantum computing, quantum supremacy or quantum advantage is the goal of demonstrating that a programmable quantum computer can solve a problem that no classical computer can solve in any feasible amount of time, irrespective of the usefulness of the problem.
Google has claimed “quantum supremacy” over the most powerful supercomputers in the world by solving a problem considered virtually impossible for even the most powerful supercomputers.
Google said the quantum system offered a combination of fewer errors and better performance than its previous systems. But the company also found out that it had to sacrifice a lot of quantum performance in order to bring stability to the system.
The Chinese team, based primarily at the University of Science and Technology of China in Hefei, reported their quantum computer, named Jiuzhang, is 10 billion times faster than Google's. A description of Jiuzhang and its feat of calculation was published Dec. 3 in the journal Science.
Google, in partnership with NASA and Oak Ridge National Laboratory, has demonstrated the ability to compute in seconds what would take even the largest and most advanced supercomputers thousands of years, achieving a milestone known as quantum supremacy.
You should be aware of the quantum stage of a claim in the event your business is involved in a dispute. Quantum refers to the monetary value the judge assigns to the loss you have suffered. In other words, quantum is the measure of how much the law values your loss.
As we scale up the computational possibilities, we unlock new computations. To demonstrate supremacy, our quantum machine successfully performed a test computation in just 200 seconds that would have taken the best known algorithms in the most powerful supercomputers thousands of years to accomplish.
Google Quantum AI announced in 2019 that it had achieved “quantum supremacy,” with its quantum computer, Sycamore, by sampling the output of a random quantum circuit faster than it claimed a supercomputer could do.
Quantum computers have not yet reached a point where they can show their supremacy over classical computers. This is mostly due to the huge amount of quantum bits, or qubits, required to perform meaningful operations on quantum computers.
The abrupt shutdown of NASA's quantum computing project was triggered by an unforeseen incident during a routine test. During the analysis of a complex simulation, the quantum computer demonstrated unprecedented computational power, solving a previously intractable problem.
Quantum computers are getting ever more powerful, but their fundamental building blocks – quantum bits, or qubits – are highly error prone, limiting their widespread use.
Google's Sycamore quantum processor was able to perform a task in 200 seconds that would have taken 10,000 years on a classical computer. We programmed the quantum computer and the world's most powerful supercomputer (at the time) to choose sequences of 0s and 1s randomly, and measured how random they were.
We are particularly interested in applying quantum computing to artificial intelligence and machine learning. This is because many tasks in these areas rely on solving hard optimization problems or performing efficient sampling.
Researchers from the Shanghai Artificial Intelligence Laboratory in China have demonstrated that their classical computing system can execute a complex computation faster and more energy-efficiently than Google's Sycamore machine.
Quantum supremacy refers to a problem-solving process by the quantum computer that cannot be solved by a classical computer in its normal lifetime. The concept is related to the speed at which a quantum computer performs.
In India, a claim under Quantum Meruit is allowed by section 70 of the Indian Contract Act that says that when a person 'lawfully' does anything for someone and does so 'non-gratuitously', and the latter enjoys the benefit of it, he (the latter) is bound to compensate the former.
A claim for quantum meruit is only available for work done before termination, where the builder has not yet accrued a contractual right for payment. The contract price will act as the cap to the value of the quantum awarded, unless circ*mstances dictate that it would be unconscionable.
Quantum is the amount of damages that are awarded to a successful party in a claim. For further information, see Measure of damages in contract and Measure of damages in tort.
