Building the next generation of quantum computers with unparalleled know-how. IQM is the European leader in superconducting quantum computers

How topology helps (and what it is)

A new study from Giulia Galli improves the accuracy of calculations on quantum computers by correcting for noise introduced by quantum hardware.

MIT PhD student Alex Greene studies superconducting quantum computing systems, working to reduce errors that limit the length and complexity of the "programs" the computers can run.

"IBM and Google currently have the world's most powerful quantum computers," says Prof. Edoardo Charbon, head of the Advanced Quantum Architecture Laboratory (AQUA Lab) in EPFL's School of Engineering. "IBM has just unveiled a 127-qubit machine, while Google's is 53 qubits." The scope for making quantum computers even faster is limited, however, due to an upper bound on the number of qubits. But a team of engineers…

Dark matter makes up about 27% of the matter and energy budget in the universe, but scientists do not know much about it. They do know that it is cold, meaning that the particles that make up dark matter are slow-moving. It is also difficult to detect dark matter directly because it does not interact with light. However, scientists at the U.S. Department of Energy's Fermi National Accelerator Laboratory have found…

SpinQ has designed 2-qubit and 3-qubit quantum computers for the education market: Gemini Mini, Gemini, and Triangulum.

Researchers at PSI have compared the electron distribution below the oxide layer of two semiconductors. The investigation is part of an effort to develop particularly stable quantum bits—and thus, in turn, particularly efficient quantum computers. They have now published their latest research, which is supported in part by Microsoft, in the journal Advanced Quantum Technologies.

To bridge the present and future of quantum computing through education.

A new hybrid quantum-classical approach could help avoid issues with noise in quantum circuits

The quantum computers offered by SpinQ are indeed remarkably smaller compared to the fastest models produced by IBM, but they are definitely not that easy to carry around, as weights vary between 14 and 44 kg, and pricing is still far away from consumer-level products. With only 2-qubit and 3-qubit processors, these systems are supposed to be educational solutions that introduce users to quantum programming.

Japan's National Institute of Information and Communications Technology, Keio University, Tokyo University of Science and The University of Tokyo succeeded for the first time in developing a method for systematically finding the optimal quantum operation sequence for a quantum computer.

I've been trying to wrap my head around quantum computing, with mixed success. I have a reasonable understanding of how quantum circuits work and the basic principles. However, there is one big missing piece in my understanding, which I've not been able to fill be googling ...You can use a tool like qiskit to create a quantum circuit, then send it to a cloud quantum computer. How does this circuit get…

Four years after Google first demonstrated the supremacy of quantum computers over ordinary ones, why aren't these exotic machines being used for practical problems?

A new housing for quantum semiconductors upends conventional wisdom, achieving more perfect computations thanks to its less-than-perfect design.
