Technology

CQ has divisions dedicated to four core domains: quantum compiler (TKET), quantum cybersecurity (Quantum origin), quantum chemistry (EUMEN), quantum machine learning, .

Quantum software development platform – TKET

TKET is an architecture agnostic quantum software development platform that enables quantum software developers to optimize large circuits for general purpose quantum algorithms. TKET's routing and scheduling protocol translates machine independent algorithms into executable circuits by optimizing for physical qubit layout while reducing the number of required operations. TKET's Python module
pytket
allows any Python user with access to a quantum computer to deploy the tket SDK in any context, including commercially.

Quantum cybersecurity - Quantum Origin

CQ has launched the first cloud-based quantum random number generation (QRNG) service with integrated verification for the user. The application developed by CQ generates true maximal randomness (or entropy) implemented on an IBM quantum computer that can be verified and thus certified as truly quantum – and therefore truly and maximally random – for the first time. This cannot be done on a classical computer.

Quantum chemistry – EUMEN

CQ has developed EUMEN, an enterprise-grade quantum chemistry platform to perform computational chemistry calculations on current quantum hardware machines. EUMEN enables the design of pharmaceuticals, speciality chemicals, performance materials and agrochemicals.

Quantum machine learning

CQ has efforts in QML with a focus on quantum circuit learning on near-term noisy intermediate-scale quantum (NISQ) computers. The company has commercial work in deploying deep learning for time-series modeling and decision-making and specializes in quantum enhanced solutions for machine learning and optimization problems.

Quantum NLP

In 2020, CQ performed quantum natural language processing (NLP) on IBM hardware. This was the first time NLP has been performed on quantum hardware.
