RIBER Deploys MBE Technology to Support Quantum Computing Materials

Bezons, December 20, 2022 – 8 am – RIBER, the global market leader in equipment for the semiconductor industry, is further strengthening its presence in the market for materials for quantum processors in 2022.

Through the joint laboratory EPICENTRE, established in Toulouse in June 2021 with LAAS-CNRS, RIBER has started Deploy the technologies that make building core components possible either next generation quantum computerThese are physical phenomena based on quantum entanglement, which occurs when two fundamental particles — two electrons (electrons) or two photons (light particles) — share the same parameters despite being far apart. Phenomenon.

This places strict demands on their production environment, which must be ultrapure, ultracontrollable and ultracold, with single-atom precision.
Technologies that can be used to deliver these levels of performance include MBE, RIBER has accumulated industry-leading expertise in material growth technology and is one of the most advantageous technologies. That’s why RIBER is part of the joint Quantum Computer Laboratory program to develop the technological components that will allow them to be built.

To generate electrons or photons, “quantum dots” are used, which are small amounts of ultrapure and ultracontrolled semiconductor alloys developed and controlled using MBE. To transport them, superconducting metals with ultra-precise dimensions (atomic scale), in which electrons flow undisturbed, can be used. The MBE technique is ideal for depositing these superconducting materials in an ultrapure environment with atomic layer controlled thickness.

These quantum dots and superconductors need to be perfectly isolated from their environment, which is achieved by depositing specialized oxide materials.

The various stages of developing quantum dots, superconductors and insulators require various deposition chambers that must have ultra-high or almost perfect vacuums to avoid any contamination. askThe acuum quality is part of the superior quality that RIBER technology provides for these MBE machines.

Thus, an MBE machine for a quantum computer would consist of several deposition chambers connected together by robots under ultra-high vacuum conditions. It may consist of three to five chambers connected by two or three robots under ultra-high vacuum conditions, controlled by highly sophisticated supervisory software that manages the sample movement and material deposition process.

Due to the complexity of such equipment due to the high number of chambers and ultra-pure, ultra-controlled and ultra-cooled performance levels, this advanced technology has a market value of several million euros per machine.

This is illustrated by the multi-million euro order for research equipment, including several chambers and equipment items announced on 25 October, to provide new European research laboratories with the flexibility and versatility of MBE to use representative Materials for future quantum computer components.

Michel Picault, Chairman of the RIBER Executive Committee, concluded: “Quantum technology holds promise, but some major developmental challenges still need to be overcome put up Specific chips. RIBER’s MBE technology will make it possible to speed up the process of mass-manufacturing quantum chips. Our joint lab with LAAS-CNRS will help us reach higher levels of technology maturity faster. “
