IBM erases the 100Kbit mark with its new processor

The company says it is on track to use 1,000 kilobits per second of useful computing by 2023.

IBM says it has overcome a major hurdle in its efforts to make quantum computing useful: it now has a quantum processor called the Eagle. Applied 127 Qubits This makes it the first company to scan the 100 qubit mark, an interesting milestone because the interactions of this number of qubits cannot be simulated using current computational algorithms and classical hardware. p>

But what may be even more important is that IBM now has a roadmap that can produce its first 1,000 kbps processor in the next two years. Here comes the role of computations using quantum hardware.

What's Up

Jill told Ars that counting qubits was new. It is the product of many developments that met for the first time. One is that IBM has switched to a "heavy hex" qubit design, which it announced earlier this year. This arrangement connects the qubits into a group of hexagons with common sides. In this design, the qubits are connected to two, three, or as many as four neighbors - on average, this is a lower level of communication than some competing designs. But Gill argued that the exchange was beneficial, saying, "It lowers the level of connectivity, but it improves interference significantly."

This improvement means that qubits have less impact on their neighbors. The ways they can present it. errors, and this allows IBM to increase the bit density on the chip. provides this possibility. Quantum control and retrieval This is common in conventional chips but new to the world of quantum computing. These wires can also carry multiplexed signals. This is important because the wires carrying these signals are large enough to limit the number of bits per chip - there won't be enough physical space for all the wires needed for a single wire to be packed into the chip. -1-one-qubit layout once the number of qubits is increased. This is the first chip made by IBM in which the wires are on a layer separate from the qubits. Zoom / This is the first chip from IBM where the Kashi wire is built. A separate layer of qubits. IBM

Other major improvements that generation highlighted include the ability to tune the microwave frequency to which each individual qubit responds and prevent so-called "collisions," where the qubit signal can be altered as well. The behavior of others "Quantum complexes - software that organizes the processes that perform computations on quantum machines - can also help prevent collisions," Gill told Ars.

Finally, IBM received a base error rate. The functional unit has been reduced For this device, the double qubit gate, to 0.001. This is very important, because if the error rate remains constant as the number of bits increases, it is more likely to miscalculate more.

What's up

of Where applications are in practice, the eagle processor doesn't do this.Changing things drastically There are probably some fun things you can do more easily with a smaller processor, but we haven't gotten to the point where we can do some useful calculations on a regular basis, which is hard Achieving it on traditional computers.In many ways, Eagle is significant as a mile marker on IBM's roadmap.This roadmap envisions a processor with more than 400 qubits next year and something with more than 1,000 qubits in 2023.(Will change to "and beyond" obscure after 2023.) The ad

was putting all the tech together in packages This is one important verification for Eagle of this roadmap. "We are confident that next year's roadmap will provide a 433-qubit system, and next year it will be possible to create a system with more than 1,000 qubits," Gill said. It also specified a lower error rate. Assuming that rate continues to decline at the same rate it has in the past few years, Gill said it should hit 0.0001 in about the same time as the 1,000 kilobits per second display. This will be sufficient for some levels of control and/or error correction, and will expand the types of algorithms that can be run on future processors.

This, says IBM, is accompanied by continuous improvements in the compiler and control is. The program will fundamentally change the use of quantum computing. "I think we're sure we can demonstrate the quantitative advantage in the next couple of years for some of the uses that have value," Gill told Ars.

Overnight, if it's on quantum hardware, everything will work better or not at all. Instead, Gill argued that the transition from our current state (a small number of error-prone qubits) would be gradual. Some specific applications will run more efficiently on the best quantum hardware in the near future. Over time, and with more improvements, we will see an increasing number of applications that Gill has dubbed the quantum advantage. But there will be no change overnight.
