Quantum error correction - geek to superhero

Quantum error correction – from geek to superhero

Quantum computers can only realise their full potential by defeating the noise that plagues their delicate qubits. The field of quantum error correction offers some increasingly mature solutions. But it is also still a rapidly evolving discipline, and innovation here, as much as in hardware, will shape the future quantum computing roadmap. If Google’s 72…

Seeding innovation in commercial quantum networks

Seeding innovation in commercial quantum networks

Next generation quantum key distribution is set to offer easier deployment on existing real-world infrastructure. The importance of partnering to offer end-to-end business services to early adopters is growing. The recent extension of the UK Quantum Network to the BT led tech cluster at Adastral Park is a powerful statement. Amid growing global competition, the…

Quantum Europe

Europe’s drive to create wealth from Quantum Technology

The focus of the EU’s €1b Quantum Flagship programme is not basic science, nor is it simply about bringing new technologies to market. The end-goal is driving wealth creation, jobs and societal benefits in Europe. This requires kick-starting the competitive position of European industry in this sector and making Europe the region of choice for…

Quantum Technology for a Global Britain?

The UK Quantum Showcase demonstrates why others around the world are seeking to copy the UK’s quantum technology approach. It’s little surprise that the UK government is providing additional funding of £315m over the next 5 years. The 2018 UK National Quantum Technology Showcase took place in the prestigious QEII conference centre overlooking London’s Parliament…

Looking beyond quantum supremacy

Striking progress modelling molecular vibrations with a quantum simulator brings the abstract quest for quantum supremacy into context. Is this a pointer to medium term commercial applications? The world is waiting for a first demonstration of quantum supremacy,  a computation not practical on any conventional computer. However behind that headline will lie a number of…

Quantum Startups

Finding winners: quantum startups

Quantum computing makes headlines, but its sister technologies of quantum cryptography and quantum sensing are reaching market sooner. The first quantum revolution began in 1901 when Max Planck showed that the light emitted from a heated black-body consists of discrete quanta, later dubbed photons. Nature turns out to be built in its entirety on the…

Quantum hardware in the NISQ era

Excitement mounts as we approach a demonstration of quantum supremacy. However a very long road remains to build a fault tolerant quantum computer Quantum hardware announcements continue to come at speed: Google has just announced Bristlecone, a 72 superconducting qubit device (though it remains to be seen if it can maintain the high fidelity performance of its…

UK National Quantum Technologies Showcase 2017

The breadth of the UK national quantum technology programme is impressive. Four flavours of qubit technology were on display, but its not just quantum computing , cryptography, sensors and imaging were just as strongly represented. Now in its third year, the momentum really shows.  Hand portable and chip scale devices that are at or near…

Quantum Computing marathon

Jury out on which platform will ultimately win the quantum computing marathon

Articles in the popular press have given competing experimentalists the opportunity for some polite scientific knocking copy A series of recent articles across the New Scientist, Financial Times and Bloomberg quote leading experimental groups, and give insight into the state of reality and hype in the nascent quantum computing sector. Different scientific groups have spent years…
