DOE’s Brookhaven Lab to lead $7M quantum physics outpost project

Brookhaven National Laboratory will lead a $7.3 million project, “Quantum Information Signatures at Colliders,” to explore how quantum information, including particle entanglement, behaves during high-energy collisions. Researchers will investigate collisions at facilities like the Large Hadron Collider and the future Electron-Ion Collider, developing new techniques to potentially identify physics beyond the Standard Model. By learning how quantum information flows through these collisions, the team aims to uncover phenomena undetectable through traditional methods. The Department of Energy stated that these projects will apply the unique tools, techniques, and concepts of quantum information science to the science mission of the Office of High Energy Physics. Quantum Information Signatures at Colliders Project Brookhaven National Laboratory is spearheading an investigation into the behavior of quantum information during particle collisions, a core component of a newly funded $7.3 million initiative. Researchers anticipate that understanding these quantum signatures will reveal phenomena undetectable by conventional methods. This effort focuses on potentially identifying physics beyond the Standard Model, the prevailing theory describing fundamental particles and forces, rather than simply observing how collisions occur. The funding for this project falls under the “Quantum Outposts on the Energy and Intensity Frontiers” program, reflecting a broader Department of Energy commitment to integrating quantum technology into fundamental physics research. Total funding across eight projects reaches $7.3 million, allocated over up to three years, with $3.2 million available in Fiscal Year 2026, contingent on congressional appropriations. This investment underscores the agency’s participation in the National Quantum Initiative and the President’s Executive Order on quantum innovation.

T-SQUARED Begins Construction on Infleqtion’s Quantum Innovation Centre in Oxford

T-SQUARED Begins Construction on Infleqtion’s Quantum Innovation Centre in Oxford Specialized engineering firm T-SQUARED has commenced construction on a new Quantum Innovation Centre at Oxford Technology Park for neutral-atom quantum technology company Infleqtion (NYSE: INFQ). The facility will triple the capacity of Infleqtion’s UK operations, expanding its research, manufacturing, and systems integration infrastructure for neutral-atom quantum computing, quantum sensing, and precision timing platforms. Following the completion of the facility design phase, T-SQUARED deployed autonomous construction layout robotics—printing millimetric architectural schematics directly onto the site floor—to accelerate physical buildout. The new infrastructure will support Infleqtion UK’s commercial scaling, system manufacturing, and talent recruitment across quantum physics, photonics, and software engineering.

Hilbert–Pólya Finds Missing Eigenstates in BBM Hamiltonian’s Metric Completion

Kejun Liu of Soochow University has completed a detailed analysis of the Hilbert space structure underlying the Bender, Brody, Müller (BBM) Hamiltonian, originally proposed as a way to model the Riemann hypothesis. The work reveals that while a completed Hilbert space can be constructed using BBM’s candidate metric, it fundamentally limits the original boundary-condition/eigenfunction mechanism intended to generate it; specifically, eigenfunctions for n greater than zero do not belong to the completed space. This finding addresses a core goal of the Hilbert-Pólya conjecture, which seeks a self-adjoint operator whose spectrum matches the imaginary parts of the nontrivial zeros of the Riemann zeta function. The analysis also demonstrates that no bounded sandwich operator is boundedly invertible, a spectral statement extending beyond the BBM problem itself, and that the transported symmetric operator possesses deficiency indices (1,1) with an adjoint exhibiting infinite multiplicity at every real eigenvalue. BBM Candidate Metric: Non-Coercivity and Completion The pursuit of a self-adjoint operator whose spectrum mirrors the Riemann zeta function’s non-trivial zeros, the Hilbert-Pólya conjecture, continues to drive innovative approaches in mathematical physics. Recent analysis of the Bender-Brody-Müller (BBM) Hamiltonian, proposed as a potential candidate, reveals fundamental limitations in constructing a suitable Hilbert space for this operator, stemming from the properties of its associated metric. The team employed a Fourier representation to dissect the BBM form, revealing that the metric assigns arbitrarily small length to normalized states concentrated near the zeros of the boundary symbol, indicating a weakening of the standard Hilbert space topology. This degeneracy is not a matter of ill-defined eigenvectors, but rather a fundamental property of the form itself; the metric “differentiates against a unit shift, so slowly varying wave packets—Fourier-concentrated
