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
