Quantum Computing's Supremacy Challenged: Classic Computing Strikes Back
Summary:
Advancements in classical computing have challenged quantum computing's touted superiority. A New York research team successfully utilized conventional computer hardware to outperform an IBM quantum computer less than a year after IBM's quantum utility demonstration. The findings emphasize how the pursuit of quantum advantage is a shifting target due to ongoing advancements in both quantum and binary computing technologies.
While quantum computing is perceived as a game-changer with the potential to solve complex issues that binary computers cannot, recent studies from a New York-based research team indicate traditional computing may not be stepping down anytime soon. In mid-2023, IBM researchers showcased a quantum system surpassing a binary computer in a specific task, a moment hailed as the "quantum utility". Nevertheless, quantum computers appear to share a common hurdle with binary computers: becoming outdated even before being commercially available.
Less than a year following IBM's notable achievement, scientists from the Flatiron Institute and New York University managed to outplay IBM's quantum computer. They utilized a conventional computer equipped with an innovative method named "tensor network approach". According to the team's recently published research paper, their inventive approach significantly surpasses the quantum computer in accuracy and precision.
In simpler terms, the so-called "quantum advantage" - a vague notion referring to the potential of quantum computing systems to perform tasks with greater speed and accuracy than binary systems - has morphed into a shifting goal post. This suggests that quantum computing, despite being in its early stages, has healthily progressed over recent years. Various labs have proclaimed exhibiting quantum utility or sometimes advantage.
However, similar to IBM's claim in June 2023, most of these leading positions are short-lived, considering the ongoing advancements within binary computer science. Quantum computing continues to evolve, with several firms promising to launch functional systems within the forthcoming years. IBM recently disclosed a projection indicating a key turning point in quantum computing by 2029. Furthermore, QuEra, a spinoff venture of MIT and Harvard, asserts it will have a 10,000-qubit error-corrected quantum computer by 2026. Then, in theory, both proposed systems should be capable of quantum utility or advantage.
