Cambridge Quantum Computing


Cambridge Quantum Computing is an independent quantum computing company, based in Cambridge, England. Founded in 2014, CQC builds tools for the commercialization of quantum technologies with a focus on quantum software and quantum cybersecurity. CQC has developed a platform agnostic quantum compiler, tket⟩, around which the company has built enterprise applications for quantum chemistry, quantum machine learning, quantum cryptography and quantum finance.
CQC was selected as one of Bloomberg L.P Business’ Top 50 Innovators in 2016.
In 2019, CQC unveiled Ironbridge, the first commercially available quantum cryptographic device at the RSA Conference in San Francisco.

History

CQC was established in 2014, and conceived through the University of Cambridge's “Accelerate Cambridge” program. Béla Bollobás, Imre Leader, Fernando Brandão and Simone Severini were its first scientific advisors.

Technology

CQC has divisions dedicated to four core domains: quantum compiler, quantum chemistry, quantum machine learning and quantum cybersecurity.

Quantum Compiler - t{\mid}ket⟩

tket⟩ is an architecture agnostic quantum compiler 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.

Quantum Chemistry - Eumen

CQC 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

CQC has efforts in QML with a focus on quantum circuit learning on near term noisy intermediate-scale quantum 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 Cybersecurity

CQC has built a 4 qubit photonics quantum device, IronBridge, to be used for post-quantum encryption, cached entropy generation for IoT devices, key generation for certificates and quantum watermarking. As of 2019, Ironbridge is the only quantum encryption device that ensures device independence and source certifiability.

Locations

CQC is headquartered in Cambridge, but has offices in London, San Francisco, Washington, D.C. and Tokyo.
