Some dentists are pushing back against the overuse of X-rays, a practice that can expose patients to unnecessary radiation and cost them extra cash.

If you’ve ever sat in a dentist’s chair, weighed down by an unwieldy, yet oddly comfortable, lead apron, wondering if your sense of time has gone completely haywire—wait, wasn’t I just here, and isn’t it too soon for more X-rays?—take comfort. You may be entirely correct.

A new study has made significant progress in quantum computing through photonic-measurement-based quantum computation. Their innovative method uses high-dimensional spatial encoding to create large cluster states more efficiently, addressing key challenges in scalability and computation speed. This paves the way for faster, resource-efficient, and fault-tolerant quantum computers.
