Arqit Announces Technology Update

Insider Brief:

  • Arqit has announced it will no longer incorporate quantum satellites or the associated ground infrastructure into its core offering.
  • Arqit intends to sell its quantum satellite currently under construction and also intends to licence its quantum satellite IP.
  • QuantumCloud will operated based entirely on classical digital hardware and software, making it more scalable, more efficient, and less risky to operate.

PRESS RELEASE — London, UK/December 14, 2022 — Arqit Quantum Inc. (Nasdaq: ARQQ, ARQQW) (“Arqit”), a leader in quantum-safe encryption, announces a significant change in its technology strategy, resulting from innovation which is expected to have a positive impact on the company’s future financial position and results.

Arqit’s technology involves the supply of a lightweight software agent to end point customer devices or cloud machines for the purpose of making encryption keys which are zero trust and computationally secure. As announced by Arqit in May 2022, the proof of this capability was independently assured by the University of Surrey, a GCHQ Accredited Centre of Excellence for Cyber Security, and PA Consulting.

As part of the background technology which allows Arqit’s software agent to operate, identical sets of random numbers (“replicated entropy”) must be delivered securely and frequently to data centres. Arqit invented a quantum satellite protocol to facilitate delivery of replicated entropy, which it believes is unique in achieving delivery with quantum safety. Pending the launch of its satellites, Arqit has been using a terrestrial method of delivering replicated entropy using a set of classical digital hardware and software elements (i.e., not quantum communications), and following further innovation this year, has recently deployed an advanced version of terrestrial delivery. The security of end point encryption keys is as strong with the terrestrial method as it is with the satellite method. Arqit has therefore concluded that it no longer needs to incorporate satellites or the associated ground infrastructure into its core QuantumCloud offering in order to deliver a quantum safe product.

There is continued demand for quantum satellite delivery of replicated entropy from customers with ultra-secure use requirements, such as government defence departments. To these customers the satellite method offers advantages in sovereign, on-premises control of key agreement and in eavesdropper detection (whereby one knows if an attacker is attempting to eavesdrop even though it cannot successfully steal information). Arqit believes that other attempts to generate security through quantum satellite transmission are flawed, and in its invention of a new set of protocols, it solved those problems. Because the security of Arqit’s quantum satellite technology cannot be deduced from individual patent filings, all the patents, code, protocols and proprietary IP have been independently validated by an eminent professor in this domain with a leading UK university and the conclusions shared under NDA with potential buyers.

Arqit intends to sell (in whole or in part as a capacity sharing arrangement) its quantum satellite currently under construction to a customer with such ultra-secure requirements. Following the sale of its satellite currently under construction, Arqit will build no further satellite infrastructure and intends to licence its quantum satellite IP to subsequent customers with similar requirements, which will enable those customers to build their own systems. Arqit is currently in discussions with a number of potential customers regarding both the purchase of its existing satellite and the licence of its quantum satellite IP. Arqit expects the licencing of its quantum satellite IP to generate additional revenues without additional capital expenditure.

Arqit expects that these changes to its technology strategy will result in a positive effect on its future results, with a portion of capitalised satellite costs recouped through the planned sale of the satellite currently under construction, additional revenues through the licencing of its quantum satellite IP and the elimination of future capital and operating expenditures associated with use of satellites as part of its core product offering. Arqit intends to continue to perform under its satellite construction contract with the European Space Agency and recognise the related project revenues generated thereunder.

Arqit’s scientists and engineers, uniquely in the world have emulated the relevant effects of quantum communications properties in classical software form. This produces a mass market encryption platform as a service which enables its customers’ systems to become quantum safe and to achieve benefits in flexibility, energy efficiency and simplicity.

Thus, as a result of further ground breaking innovation, Arqit believes that its core QuantumCloud product is greatly simplified relative to the version of the network architecture that included satellites. Based entirely on classical digital hardware and software, QuantumCloud will now be more scalable, more efficient, and less risky to operate. As demonstrated by recent announcements, major corporate and cloud customers are choosing to use this product.

David Williams, Founder, Chairman and CEO said:

Through innovation we have simplified our technology and removed significant future capital expenditures. The resulting software is now easier to support and consume by customers and is suitable for a high growth, annual recurring revenue style business. The White House has urged all Federal Organisations to upgrade to post quantum cryptography and the NSA has declared that symmetric key encryption is the best way to do that. We believe that Arqit is the only company in the world that can deliver this in a zero trust and scaled way. Now, through channel partners like AWS, Dell and Fortinet, the world can buy the stronger, simpler encryption it urgently needs.
