Quemix reconstructs quantum states from basis-function overlaps, shows reduced measurements in simulation
A method that approximates a quantum state as a combination of basis functions and reconstructs it with fewer measurements than conventional methods was demonstrated in numerical simulations.

Quantum Machines runs CUDA‑Q programs across qubits, PPU, GPU and CPU via NVQLink with ~1 µs round trip
A single program written in CUDA‑Q was executed across real qubits, a PPU, GPU and CPU. Quantum‑to‑classical information exchange took about 1 microsecond.
