Amsterdam’s QDNL Participations Rebrands as Ground State Ventures, Secures Over €75.2M for Early-Stage Quantum Fund Amsterdam-based specialized venture capital firm QDNL Participations has announced its formal corporate rebranding to Ground State Ventures as it prepares the final close of its inaugural early-stage quantum technolog

Welcome to the Quantum News Daily Brief. Story 1: Spin singlets are useful. A team led by Silas Hoffman and Charles Tahan demonstrated that the spin-zero manifold of an exchange-coupled spin array in semiconducting quantum dots can unlock a Hilbert space of dimension approximately 2^N/(N/2)^(3/2), nearly matching the full 2^N spin space. Using exchange-only control, they showed this approach surpasses traditional modular encoding, which restricts arrays to a Hilbert space of 2^(N/n). The study g

Welcome to the Quantum News Daily Brief. Story 1: Lean-Quantum: Toward AI-Assisted Formalization of Quantum Information. A team led by Kazumi Kasaura has developed Lean-Quantum, a Lean 4 library that formalizes quantum information theory, enabling machine-checkable proofs. The library establishes a basis-independent framework for finite-dimensional quantum mechanics, compatible with Mathlib, and includes interfaces for states, channels, tensor products, and key representations like Choi and Krau

Welcome to the Quantum News Daily Brief. Story 1: COMET: Combinatorial Optimization for Multiplex Editing Targets Via Constraint-Preserving QAOA. A team led by Priyansh Singhal, Sumit Maheshwari, and Piyush Joshi introduced COMET, a method comparing constraint-enforcement strategies for multiplex CRISPR-Cas9 gene editing using QAOA. Their study targets immune-checkpoint genes PDCD1, LAG3, and HAVCR2 on a twelve-qubit system. In simulations, the XY-mixer approach achieved over 95% probability of
