A month after Intel released its 17-qubit chip, IBM is making a jump towards Quantum supremacy and announced computer with 50-Qubit Quantum Computer. The announcement was made in the IEEE Industry Summit on the Future of Computing in Washington D.C. With this 50-Qubit computer IBM has built most powerful computer till now.
“We are really proud of this; it’s a big frickin’ deal,” IBM’s director for AI and quantum computing Dario Gil, who made Friday’s announcement, told the MIT Technology Review.
While traditional computers user 0s or 1s to store the data, quantus computers can use 0s and/or 1s simultaneously. This is made possible by the quantum effects known as entanglement and superposition.
By announcing 50-qubit quantum computer it doesn’t mean that it will be available for common use. In this computer IBM has preserved quantum state for 90 seconds — a record in the industry but very short time.
IBM is also announcing an upgrade to its quantum cloud software system today. “We’re at world record pace. But we’ve got to make sure non-physicists can use this,” Gil says.
Google has also tested chips with 6 and 9 Qubits and on its way to achieve 49 Qubits, expected to ready by the year end.
Furthermore, as University of Maryland professor Andrew Childs pointed out to MIT Tech Review, IBM hasn’t yet published the details of their new machine in a peer-reviewed journal. “IBM’s team is fantastic and it’s clear they’re serious about this, but without looking at the details it’s hard to comment,” he said, adding that more qubits doesn’t necessarily translate to a leap in computational ability. “Those qubits might be noisy, and there could be issues with how well connected they are.”
Its very high jump by IBM in quantum computer but lots of work need to be done. As we are just into infancy of the quantum computing.
