Three Caltech Professors Named Fellows of the American Physical Society

Caltech professors Marco Bernardi, Sujit Datta, and John Sader have been named fellows of the American Physical Society (APS) for their outstanding contributions to physics. Marco Bernardi , professor of applied physics, physics, and materials science and the undergraduate and graduate option representative for materials sciences, was nominated by the APS Division of Computational Physics (DCOMP). He studies quantum interactions and dynamics in matter, picking apart the processes that take p...

Quantinuum and HQS Simulate 21-Spin NMR Spectrum on 42 Qubits With 1,400+ Two-Qubit Gate Circuits

Quantinuum and HQS Quantum Simulations successfully simulated a 21-spin NMR spectrum on Quantinuum's 42-qubit quantum computer, the H2-1. This simulation, which modeled 1,2-di-tert-butyl-diphosphane, demonstrated the viability of deep digital Hamiltonian simulation for complex NMR challenges, even reproducing a subtle double-peak structure that previous systems struggled with. This advancement, detailed in a preprint on arXiv, marks a significant step for quantum computing in scientific resea...
