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.

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.

Rigetti Computing, Inc. (“Rigetti” or the “Company”), a pioneer in full-stack quantum-classical computing, announced today that it was selected to participate in the Defense Advanced Research Projects Agency (DARPA) Quantum Benchmarking Initiative (QBI). The primary goal of QBI is to determine if any approach to quantum computing can achieve utility-scale operation by 2033. QBI will use a multi-stage approach, Stages A, B, and C, to assess the proposed concepts, with each stage representing an increased level of scrutiny. Rigetti will advance to Stage A, a 6-month performance period focused on the Company’s utility-scale quantum computer concept worth up to $1 million upon completion of program milestones.

Iceberg Quantum today announced its launch, a $2 million pre-seed funding round, and a partnership with PsiQuantum. The company is developing fault-tolerant quantum computing architectures based on LDPC codes, with the goal of accelerating the path to useful quantum computing using significantly less hardware.

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.

University of Arizona College of Engineering researchers Christos Gagatsos and Bane Vasic received two grants from the federal government to advance novel areas in quantum information. Gagatsos was awarded $1.4 million from the U.S. Army Research Office to investigate the application of quantum error correction in magnetic field sensing, and Vasic was awarded $600,000 from the National Science Foundation to stabilize quantum computing with error correction codes.

The ParityQC team is proud to present the new paper “Fault-tolerant quantum computing with the parity code and noise-biased qubits”, introducing a new approach to error correction in quantum computing that combines the Parity error correction code with noise-biased qubits.
