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.

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.

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.

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.

Exchange-mediated spin–electric control of single molecules on surfaces

Researchers demonstrate spin–electric coupling (SEC) in two molecular spin systems—iron phthalocyanine (FePc) and Fe–FePc complexes—on MgO/Ag(001) surfaces using electron spin resonance combined with scanning tunnelling microscopy (ESR–STM). By varying the DC bias voltage, they observe a strongly nonlinear resonance frequency shift reaching up to ~30%, far exceeding previous reports. This nonlinear behavior is attributed to a transport-mediated exchange interaction (exchange bias) between the magnetic STM tip and the molecular spin, linked to the energetic position of the molecular LUMO. The mechanism is validated by full transport simulations and DFT calculations. The team further demonstrates all-electrical coherent spin control via Rabi oscillation measurements on single and coupled Fe–FePc dimers, showing that individual spins can be selectively detuned using only DC voltage. This exchange bias mechanism is highly localized, broadly applicable, and opens a pathway toward electrically controlled quantum gate operations in molecular spin assemblies.

SandboxAQ Brings Quantum-Inspired Large Quantitative Models to Google Cloud Marketplace

SandboxAQ is bringing its Large Quantitative Models (LQMs) to Google Cloud Marketplace, making physics-based AI models accessible without specialized code or infrastructure. The first two models, AQCat and AQPotency, are slated for Q3 availability. AQCat targets catalyst and materials discovery by calculating adsorption energy to rapidly screen candidates, while AQPotency enables high-throughput computational screening of drug candidates. The move extends SandboxAQ's strategy of integrating LQMs with major AI platforms, following a prior integration with Anthropic's Claude, and pairs its quantitative precision with Google's Gemini frontier model.
