About Arqit

Symmetric encryption reborn for the cloud

Our mission

We use transformational quantum encryption technology to keep safe the data of our governments, enterprises and citizens

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 7 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”.
