Stronger simpler encryption

Arqit supplies a unique quantum encryption Platform-as-a-Service which makes the communications links of any networked device secure against current and future forms of attack – even from a quantum computer.  Arqit’s product, QuantumCloud™, enables any device to download a lightweight software agent of less than 200 lines of code, which can create encryption keys in partnership with any other device.  The keys are computationally secure, one-time use and zero trust.  QuantumCloud™ can create limitless volumes of keys in limitless group sizes and can regulate the secure entrance and exit of a device in a group.  The addressable market for QuantumCloud™ is every connected device. 

On 3 September 2021, Arqit completed its business combination with Centricus Acquisition Corp. (“Centricus”) a special purpose acquisition company. The combined company has retained the name Arqit Quantum Inc.  Arqit trades on Nasdaq under the ticker symbols “ARQQ” and “ARQQW”.
