A quantum sampler leaves the whiteboard
Drug discovery often begins with a search through more molecular possibilities than any laboratory could test one by one. A quantum version of a familiar sampling routine has now run on Quantinuum's H2 and Helios systems, producing accurate results on physical qubits in a tightly bounded experiment. Its practical implication is demanding: useful sampling methods must survive hardware noise before their theoretical speedups can help molecular research.
The heart scan that keeps almost arriving
Magnetocardiography reads the faint magnetic field thrown off by the heart's own electrical activity, without touching the patient. It is around sixty years old, it keeps producing evidence that it sees things a standard ECG cannot, and it is still not accepted as a routine
