By Matthew Sparkes Google’s Sycamore quantum processor is one of the most advanced Peter Kneffel/dpa/Alamy A POWERFUL quantum computer could crack encryption and solve problems that classical machines find impossible. Although no one has yet succeeded in building such a device, recently we have seen a gathering pace of progress – so could 2022 be … Read more
IBM has created the world’s largest superconducting quantum computer, surpassing the size of state of the art machines from Google and Chinese researchers. Previous devices have demonstrated up to 60 superconducting qubits working together to solve problems, but IBM’s new Eagle processor more than doubles that by stringing together 127.

By Matthew Sparkes Google’s Sycamore quantum processor set a record in 2019 that has since been beaten Peter Kneffel/dpa/Alamy Live News A quantum computer made by researchers in China has solved a calculation in 4.2 hours that would take a classical computer thousands of years. This demonstration of what the researchers call “quantum computational advantage” … Read more
By Matthew Sparkes Quantum computers may be the perfect tool for designing quantum computers sakkmesterke/Shutterstock A quantum computer has been used to design an improved qubit that could power the next generation of smaller, higher-performance and more reliable quantum computers. Exploiting the ability of quantum processors to simulate the behaviour of quantum circuits that classical … Read more
By Matthew Sparkes A silicon quantum circuit being connected to a circuit board Serwan Asaad Quantum computers tend to be labyrinthine machines the size of a fridge with large tangles of control and cooling systems. This complexity is a huge hurdle to scaling up processor power to tackle harder problems. But researchers have finally proved … Read more
