Nearly 20 quantum computing companies have been chosen to enter the initial stage of DARPA’s Quantum Benchmarking Initiative (QBI), in which they will characterize their unique concepts for creating a useful, fault-tolerant quantum computer within a decade.

QuantWare, the quantum computing company building technology to create the world’s most powerful quantum processors, has raised a €20 million Series A round.

Microsoft today introduced Majorana 1, the world’s first quantum chip powered by a new Topological Core architecture that it expects will realize quantum computers capable of solving meaningful, industrial-scale problems in years, not decades.

In a milestone that brings quantum computing tangibly closer to large-scale practical use, scientists at Oxford University Physics have demonstrated the first instance of distributed quantum computing. Using a photonic network interface, they successfully linked two separate quantum processors to form a single, fully connected quantum computer, paving the way to tackling computational challenges previously out of reach. The results have been published today in Nature.

IQM Quantum Computers (IQM), a global leader in superconducting quantum computing, today announced its development roadmap with technical milestones targeting fault tolerant quantum computing by 2030, while enabling a dedicated Noisy Intermediate-Scale Quantum (NISQ) approach for near-term usage.

IonQ, a leader in the quantum computing industry, announced it has achieved the next milestone on the path towards scaling its quantum systems – demonstrating remote ion-ion entanglement. Building off the ion-photon entanglement achievement announced in February, this demonstration announced in September showcases the second out of four significant milestones required to develop photonic interconnects – a foundational step towards quantum networking and a core component of IonQ’s scaling strategy.

IonQ, a leader in the quantum computing industry, today announced a new breakthrough towards running large applications on near term quantum systems using partial error correction. The technique is an order of magnitude more efficient than the best error correction techniques known today.

Quantum computers with millions of qubits are essential to solving some of humanity's toughest challenges. Integrating key qubit control electronics into the quantum chip architecture that holds the qubits is critical to achieving that scale.

onQ, a leader in the quantum computing industry, today announced it has generated photons entangled with ions repeatedly and reproducibly, creating a quantum state which allows future quantum systems to communicate and transfer information between each other.
