QuTech Demonstrates Coherent Diamond Quantum Emitter Interface for Quantum Networks

QuTech researchers have demonstrated a coherent interface between a diamond tin-vacancy (SnV) quantum emitter and a nanophotonic optical cavity, marking a significant step toward scalable quantum networks. The team achieved coherent cooperativity above unity — a key threshold for high-fidelity quantum operations — and showed that a single quantum emitter can nearly completely control light transmission through the cavity. They also fabricated and tested 327 high-quality nanophotonic cavities across two chips, validating a scalable manufacturing approach. The work, published in PRX, is relevant to both quantum networking and modular quantum computing, including a collaboration with Fujitsu.

Top Quantum Computing Investors in 2026

A comprehensive overview of the leading quantum computing investors in 2026, covering dedicated quantum VC funds (Quantonation, 55 North, Firgun Ventures), corporate venture arms (Google Ventures, IBM Ventures, Microsoft M12, Amazon), sovereign wealth funds (Temasek, Mubadala), and government-backed programs (In-Q-Tel, SGInnovate, HTGF). Private VC in quantum reached $4.9 billion in 2025, more than doubling the prior year. The piece profiles each investor's focus, confirmed portfolio companies, preferred funding stage, and geographic orientation. It also covers how to pitch quantum investors, key metrics they evaluate (qubit count, gate fidelity, coherence times, commercialization roadmap), typical funding amounts by stage, and the complementary roles of government grants versus venture capital for quantum startups.

Former Microsoft Quantum CTO’s New Chinese-Based Startup Lands Pre-A Funding

Taiyi Quantum, a six-month-old Shanghai-based startup, has raised 300 million yuan (~$44M USD) in a Pre-A funding round led by Gaorong Venture Capital and IDG Capital. The company is led by Liu Hongbin, a former Microsoft Azure Quantum Principal Architect who worked on Microsoft's neutral-atom initiative with Atom Computing. Taiyi is developing a ytterbium-based neutral-atom quantum computer, leveraging laser-trapped atoms as qubits. Ytterbium offers advantages including stable nuclear-spin qubit states, precise laser control, and reduced noise compared to alkali atoms like rubidium or cesium. The large raise for such a young startup signals growing investor confidence in China's quantum computing sector.

Yale Officials Say $4 Million NSF Grant Will Boost Unique Approach to Quantum Computing

Yale's ERASE project has received a $4 million NSF grant to fund a two-year second phase focused on developing a blueprint for a large-scale, error-correcting quantum computer. The project centers on erasure qubits — dual-resonator quantum bits that can flag dominant errors as they occur, simplifying error correction. Partners include D-Wave Quantum (which acquired Yale spin-off Quantum Circuits Inc.), Princeton, the University of Maryland, and Southern Connecticut State University. The phase will expand research, software, algorithm development, and quantum workforce training in Connecticut, with a detailed hardware plan for a future Phase 3.

University of Maryland Grant Targets Quantum and AI Tools for Cancer Research

The University of Maryland is funding a research project combining quantum computing and machine learning to accelerate the discovery of single-atom catalysts for cancer detection and treatment. Part of the university's Grand Challenges Grants Program, the project brings together engineers and computer scientists to build a predictive framework that models complex atomic and chemical behaviors — tasks difficult for classical computers. Quantum simulations would generate reliable databases of electronic structures and catalytic pathways, which machine learning models would then search to identify promising catalyst configurations. The team also plans to release benchmark datasets and reproducible computational tools to support open science. The research is preclinical and focused on discovery, not immediate clinical application.

Physicists Set Sail on a Strange Quantum State Called a Fractional Fermi Sea

Researchers from the Nägerl group and collaborators have demonstrated that a one-dimensional gas of ultracold cesium atoms can be driven into a novel non-equilibrium quantum state called a 'fractional Fermi sea.' By cyclically switching particle interactions between strongly repulsive and strongly attractive regimes, the atoms reorganize into a highly excited yet highly ordered many-body state rather than simply heating up. This state exhibits distinct correlation patterns — including Friedel oscillations — that differ from the established Tomonaga-Luttinger liquid model, suggesting an entirely new exotic critical phase of matter. The findings open new pathways for quantum simulation beyond known equilibrium paradigms, with the experimental realization paper still under review.
