新しい理論研究により、高速で移動する鏡を使って光子を分割しようとすると、元の粒子が短くなるのではなく、無限に多くの光子が重なり合った状態が生じることが示された。
オスロ大学のJohannes Skaar氏率いる研究チームは、光子がその波状のテールの部分のみを反射するほど高速で移動する鏡に遭遇した際に何が起こるかを調査した。電磁場の量子方程式を解析した結果、この相互作用により、量子真空のゆらぎに起因して無限に多くの光子が混在した状態が生成されることが明らかになった。

Physicists at MIT have developed a new microscope using terahertz light to directly observe hidden quantum vibrations inside a superconducting material for the first time. The device compresses terahertz light to overcome its wavelength limitations, revealing frictionless electron flows in BSCCO. This breakthrough could advance understanding of superconductivity and terahertz-based communications.
Physicists have published research proposing that a single clock could tick both faster and slower at the same time due to quantum effects. The work combines relativity and quantum mechanics in a novel way. Researchers say advances in atomic clock technology may soon allow the idea to be tested in the lab.

Researchers at Tokyo University of Science have demonstrated matter-wave diffraction in positronium, an exotic atom formed by an electron and its antimatter counterpart, a positron. This marks the first observation of quantum interference in such a system. The findings, published in Nature Communications, confirm positronium's wave-particle duality.
Scientists have created the first complete design for a quantum version of a pendulum clock using a single atom, mirrors and light. The device could advance understanding of timekeeping at the quantum scale.
