IBM's Quantum Processor Shatters Supercomputer Records with 1 Million Sample Generation in 19 Seconds
IBM's quantum processor Nighthawk r2 has demonstrated significant performance in a random circuit sampling test, generating 1 million samples in just 19 seconds. This achievement is noteworthy because it surpasses what would be possible with even state-of-the-art supercomputers, which would require around 110 years to accomplish the same task.
The experiment was conducted by a team led by theoretical condensed matter physicist Tigran Sedrakian from BlueQubit, and used IBM's commercially available quantum processor. The team applied random circuits of up to 40 cycles on the 61-qubit Nighthawk r2 and estimated that computing a single output amplitude would require complex-number operations of about 10^22 power.
The result is considered a demonstration of 'quantum advantage,' which refers to the ability of quantum computers to perform computations that are practically difficult for classical computers. However, it's essential to note that this achievement is specific to the random circuit sampling test and may not translate to other industrial applications.
