Diamond Spin Register Entangles Four Qubits in 14.8 Microseconds
University of Pennsylvania researchers entangled an electron spin with three nuclear memory qubits in diamond at room temperature using one dynamical decoupling sequence rather than a chain of pairwise gates
Dell and Diraq Place Silicon Qubits Beside HPC Servers
Diraq and Dell Technologies have installed a Dell HPC cluster beside Diraq's silicon spin-qubit hardware in Sydney to test real-time orchestration, calibration and quantum-classical control workflows without claiming quantum advantage.
Quantum Models Target Rare Earth Separation Chemistry
USA Rare Earth, Pasqal and Riven Systems are developing a quantum-machine-learning workflow to identify selective extractants for separating mixed rare earth carbonate into individual oxides, using thousands of automated experiments and feedstocks from mining and recycling.
