Quantum processor from Japan based on Tyrol

Quantum processor from Japan based on Tyrol

NEC is now making the quantum computer, which specializes in optimization problems, accessible to science via the cloud. All over the world, scientists and companies are working hard to build quantum computers. These new computing machines will solve many problems faster and more efficiently than previous technologies.


ParityQC architecture with NEC superconducting paratrons

Especially in the search for optimal solutions to complex problems, quantum technology promises practical applications very soon. The basis for this is quantum annealing systems or static quantum computers, which do not operate with gate operations like classical computers. Instead, they use a quantum property to search for the optimal state in a physical system. Packed in suitable algorithms, these systems can be used to find optimal solutions to many problems.

Japanese quantum chip with Tyrolean know-how

The NEC IT group has now built an 8-bit quantum slurry based on the Innsbruck spin-off ParityQC architecture. The first parabolic quantum chip consists of superconducting parametron qubits, and is now made available to science by NEC via the cloud. “This is an impressive confirmation of the actual advantages offered by the ParityQC approach: immunity to noise and scalability to a fully interconnected quantum computer while maintaining long coherence times,” says Hermann Hauser enthusiastically, an Austrian-born physicist and investor involved in the share-ups.

“extraordinary success”

According to Hauser, the acquisition of the ParityQC architecture by NEC, one of the world’s leading supercomputer companies, is an exceptional success for the four-year-old spin-off from the University of Innsbruck. It makes ParityQC the world’s first quality control architecture firm with proven and effective implementation. The benefits of this approach may lead to the ParityQC design being adopted by many other hardware manufacturers. “A number of recent announcements from quality control associations in Europe really support this,” says Hauser.

NEC was the first company to introduce superconducting qubits in the 1990s. We are very proud that their quantum processor, which will now be available for external use for the first time, is based on our architecture,” say Wolfgang Lechner and Magdalena Hauser, co-directors of ParityQC.

The technology is based on an idea from Innsbruck

ParityQC was founded in Innsbruck in 2020 and commercializes a technology based on a now patented idea developed by quantum physicist Wolfgang Lechner in 2010 with Peter Zoller and Philipp Hauke ​​at the University of Innsbruck and the Institute of Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy for science.
