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.

Riverlane, the global leader in quantum error correction technology, today announced that it has raised $75 million in Series C funding to deliver its groundbreaking quantum error correction (QEC) roadmap. The funding will enable Riverlane to expand operations to meet surging global market demand for QEC technology, with the goal of achieving one million error-free quantum computer operations by 2026.

Now, a team of scientists led by researchers at the Pritzker School of Molecular Engineering (PME) at the University of Chicago have developed the blueprint for a quantum computer that can more efficiently correct errors. The system uses a new framework, based around quantum low-density party-check (qLDPC) codes — which can detect errors by looking at the relationship between bits — as well as a new hardware involving reconfigurable atom arrays, which allow qubits to communicate with more neighbors and therefore let the qLDPC data be encoded in fewer qubits.

Quantinuum, the world’s largest integrated quantum computing company, together with Microsoft, has achieved a breakthrough in making fault tolerant quantum computing a reality, by demonstrating the most reliable logical qubits with active syndrome extraction, an achievement previously believed to be years away from realization.

Alice & Bob, a leading hardware developer in the race to fault tolerant quantum computers, in collaboration with the research institute Inria, today announced a new quantum error correction architecture – low-density parity-check (LDPC) codes on cat qubits – to reduce hardware requirements for useful quantum computers.

Nord Quantique, a leading maker of quantum computers with efficient error correction, today proudly announces it has been accepted into stage A of DARPA's Quantum Benchmarking Initiative (QBI). The company is one of a handful emanating from around the world which have been accepted into this prestigious program. This acceptance is based on Nord Quantique's advanced approach to quantum error correction, which is designed to progress efficiently to utility scale. This multi-year initiative will roll out in several stages, with companies achieving certain milestones being retained for successive stages and winning contracts based on their performance.

QuantWare and QuantrolOx have announced a joint offering enabling quantum computer researchers to develop error correction capabilities using QuantWare’s flagship error-correction Contralto-A quantum processor with the automated tuneup of QuantrolOx’s Quantum EDGE software.

Xanadu, a leader in photonic quantum computing, has published a research article in the peer-reviewed journal Physical Review Letters, demonstrating how photonic qubits can be used to enact any quantum error correction (QEC) code—including codes that use a lot less qubits to suppress errors. This work opens the door to reducing the number of physical qubits needed for early fault-tolerant quantum computation, while preserving an error correction threshold comparable to other performant QEC codes. The flexibility and feasibility of Xanadu's photonic approach is highlighted, especially when considering the finite qubit resources that will be available in early utility-scale quantum computers.

In an industry first, Photonic Inc. has introduced a new, low-overhead family of Quantum Low-Density Parity Check (QLDPC) codes that can efficiently perform both quantum computation and error correction, using materially fewer quantum bits (qubits) than traditional surface code approaches. This milestone work will accelerate the timeline to useful quantum computing.

IQMQuantum Computers, Riverlane, and Zurich Instruments have announced the launchof the SurgeonQ project, a strategic collaboration to create the first quantumcomputing platform capable of running multiple real-time quantum errorcorrection operations. The project represents progress towards commerciallyviable quantum computing systems.
