introduced a quantum chip called Majorana 1. The company said it has the elements needed to scale to 1 million qubits in a palm-sized processor capable of powering more advanced research models than the ones available today. Qubits are the fundamental unit of information in quantum computing.

Quantum chips typically have 50 to a few hundred qubits. A notable exception is IBM’s 1,121-qubit quantum processor, Condor, which was unveiled in 2023. Today, Majorana 1 has only eight qubits, but

is confident it can hit the million mark.

“A million-qubit quantum computer isn’t just a milestone — it’s a gateway to solving some of the world’s most difficult problems,”

’s path to a scalable quantum processor stemmed from the company’s researchers designing and fabricating an indium arsenide and aluminum material stack almost atom by atom to produce, with the help of magnetic fields, new quantum particles called Majoranas. The particles become topological qubits, which means the key features needed to carry data reliably are embedded in the Majorana.

The instability of qubits in quantum systems requires researchers to spend so many resources on error correction that the number of reliable qubits is insufficient for large-scale computing.

“Quantum is seen as the next big thing in computing,” Jack Gold, principal analyst for J.Gold Associates, said. “The trouble is that there isn’t one technique. There’s still a lot of experimentation.”

Practical quantum computers for enterprises are years away, but less than the 20 years predicted by Nvidia CEO Jensen Huang in January, Gold said.

“In five to 10 years, we will have useful quantum computers,” he said. “We already have a few really small ones. They’re not great because they’re tiny.”

Quantum computing systems are mainly sold to research institutions and organizations running specialized applications. D-Wave Systems is an example of a quantum computer maker.

For quantum computing to become mainstream, a lot of supporting technology must be developed, such as programming languages to write applications. Also, quantum computers today need near-zero temperatures to operate, an expensive requirement that remains one of the biggest challenges to commercializing the systems.

“A research project is one thing, but building a cost-effective system that people can afford to use is a different battle,” Gold said.
