Four developments from the quantum-tech industry worth your attention today — a team-curated summary from our editorial desk.
Tsinghua Researchers Unveil “Cornucopia” Codes for Ultra-Low-Overhead Quantum Error Correction
Physicists Zhide Lu, Weikang Li and Dong-Ling Deng at Tsinghua University have proposed a new family of quantum low-density parity-check codes, dubbed Cornucopia codes, built for reconfigurable neutral-atom quantum computers. The codes combine an encoding rate above 1/2 with a pseudo-threshold above 0.4% under standard circuit-level noise, co-designing the code layout, atom rearrangement and syndrome-extraction schedule so that long-range error checks can run through simple, parallel atom movements — a combination that has been difficult to achieve in a single code family. If it holds up experimentally, the approach could cut the number of physical qubits needed to protect each logical qubit, a persistent bottleneck for scaling neutral-atom hardware.

Rigetti Creates Dedicated Systems Delivery Unit, Names New COO and CTO
Rigetti is establishing a dedicated Systems Delivery organization to handle the growing number of on-premises deployments of its Novera and larger Cepheus-class quantum systems, separating that commercial delivery work from its core processor research and development. David Rivas has been named the company’s first Chief Operating Officer, overseeing systems delivery, manufacturing operations and customer-facing engineering, while Andrew Bestwick becomes Chief Technology Officer, focused on quantum processor development and chip fabrication. Rigetti said the reorganization reflects rising demand for its hardware, spanning 9-qubit Novera systems to 108-qubit Cepheus-class machines.

University of Wisconsin–Madison Spinout Dirac Labs Raises $1.8M for Diamond-Based Quantum Navigation Sensors
Dirac Labs, a spinout of the University of Wisconsin–Madison, closed a $1.8 million pre-seed round led by TitletownTech, a venture firm backed by Microsoft, to prototype and field-test its diamond-based quantum navigation sensors. The system pairs quantum magnetometry with AI-based signal processing to read fine variations in Earth’s magnetic field, aiming to provide GPS-independent positioning for defense and commercial platforms operating underwater, underground or in other environments where satellite navigation is unreliable.

Paris Startup ColibriTD Raises €4M Seed to Scale Quantum Simulation Software
Paris-based ColibriTD closed a €4 million seed round led by Earlybird Venture Capital, with participation from SymbiaVC and Medin VC, to expand its Hybrid Differential Equation Solver (H-DES) — a quantum-classical algorithm for solving partial differential equations used in aerospace, energy and automotive simulation. Founded in 2019, ColibriTD has run co-construction projects with organizations including Thales, the European Space Agency (ESA), and BMW, and will use the funding to grow its research team and hardware partnerships.
