PRESS RELEASE — August 17, 2023 (AEST): Silex Systems Limited (Silex) (ASX: SLX) (OTCQX: SILXY) — is pleased to announce the award of $5.1m in funding from the Defence Trailblazer for Concept to Sovereign Capability Program, a strategic partnership between The University of Adelaide and UNSW Sydney (UNSW), supported by the Australian Government Department of Education through the Trailblazer Universities Program. The funding will support the establishment of a Quantum Silicon Production Plant, which aims to deliver an end-to-end manufacturing facility at the Company’s Lucas Heights technology centre. It is anticipated that the first production module will produce between 5kg to 10kg annually of ZS-Si (in the form of halo-silane), which will then be converted to multiple Q-Si product forms for potential customers in the global silicon-based quantum computing industry. The new project will be undertaken in conjunction with partners, Silicon Quantum Computing Pty Ltd (SQC) and UNSW, and follows on from an earlier project that demonstrated efficient production of gram quantities of ZS-Si, with enrichment of silicon-28 up to ~99.998% purity. Michael Goldsworthy, Silex’s CEO/Managing Director, said: “We are delighted to receive funding under the Federal Government’s Defence Trailblazer Program, which will assist us to transition our Zero-Spin Silicon enrichment technology from the pilot demonstration level to commercial-scale, including the development of product conversion technology to produce two forms of commercial Quantum Silicon products (gas and solid) required by emerging silicon quantum chip fabricators around the world.” “This enables us to capitalise on the results achieved in the recently completed Zero-Spin Silicon Project for our innovative SILEX laser isotope separation technology, and to establish a sovereign capability and secure supply chain for this critical enabling material for the emerging silicon quantum computing industry. Previously, the main supply of enriched silicon came from Russia, but this source has been disrupted by geopolitical events”, he added. Professor Michelle Simmons AO, CEO of SQC, said: “Following the successful collaboration under the CRC-P program, SQC is tremendously excited about the expansion of our partnership with Silex through the Trailblazer Quantum Silicon Production Project. The Trailblazer funding supports Silex’s commercial-scale production of Quantum Silicon, the key enriched silicon material essential to the manufacture of SQC’s atom-scale quantum computers in Australia. The creation of a sovereign supply of this vital material comes at a time when our traditional source of supply has been disrupted. We couldn’t be more motivated to support this Project.” Dr Sanjay Mazumdar, Executive Director, Defence Trailblazer, said: “The Defence Trailblazer looks forward to supporting the commercial deployment of Silex’s Quantum Silicon Production Plant. The intent of the Defence Trailblazer Program is to support the commercialisation of Australian technologies that will have a material benefit to the Defence sector in Australia. Through the Quantum Silicon Production Project, a sovereign end-to-end supply chain for critical quantum materials essential for silicon quantum computing will be created. The advent of quantum computing is expected to have profound impacts on Defence and National Security activities, and this Project is a perfect fit with the intent of the Trailblazer.” Professor Nicholas Fisk, Deputy Vice-Chancellor Research and Enterprise, UNSW Sydney, said: “UNSW Sydney is extremely pleased to support Silex and SQC in the Quantum Silicon Production Project under the Defence Trailblazer Program, in partnership with The University of Adelaide. As a major shareholder in SQC, and as the Administering Organisation for the Australian Research Council Centre of Excellence for Quantum Computation and Communication Technology, we have been impressed with the achievements in the previous CRC-P project for the development of ZS-Si production technology, and are excited to support the next step for commercial-scale production of Quantum Silicon. This Project is of critical importance to Australia’s ability to maintain leadership in an increasingly competitive and strategic endeavour to develop the world’s first scalable quantum computing technology.” Contributing to the ‘Quantum Materials, Technologies and Computing Theme’ under the Defence Trailblazer Program, quantum computing capability is emerging as a vitally important strategic and national security technology, as evidenced by the global race to establish early mover advantage. The Trailblazer funding will support the commercialisation of Q-Si products for use in defence and civilian markets (domestic and offshore), while cementing areas of critical sovereign capability within Australia. Quantum technologies are expected to have a profound impact on our way of life in the decades to come, with quantum computing to open new frontiers and opportunities for defence and national security. The Q-Si Production Plant will include equipment for conversion of ZS-Si (in the form of halo-silane) into different product forms that are compatible with silicon quantum chip fabrication technologies utilised by manufacturers, namely: Quantum Silane gas — used in chemical vapour deposition (CVD) based processes utilised for quantum chip fabrication Quantum Silicon solid — used in atomic and molecular beam epitaxy (ABE / MBE) based processes utilised for quantum chip fabrication. A key benefit of the SILEX laser isotope separation technology is its modular nature, allowing the possibility for the production plant to be scaled up with additional modules, based on market demand and other factors. The 3.5-year Project has a total budget of ~$16m, of which $5.1m in funding will be provided by the Defence Trailblazer. Silex is currently resolving other avenues of financial support for the Project. Authorised for release by the Silex Board of Directors.
