تُظهر دراسة نظرية جديدة أن محاولة تقسيم فوتون باستخدام مرآة تتحرك بسرعة فائقة تؤدي إلى تكوين تراكب لعدد لا نهائي من الفوتونات بدلاً من تقصير الجسيم الأصلي.
بحث فريق من الباحثين بقيادة يوهانس سكار في جامعة أوسلو ما يحدث عندما يواجه فوتون مرآة تتحرك بسرعة كافية لعكس جزء فقط من ذيله الموجي. وكشفت المعادلات الكمية للمجال الكهرومغناطيسي أن التفاعل ينتج حالة تمزج عدداً لا نهائياً من الفوتونات بسبب التقلبات في الفراغ الكمي.

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.

An international research team has developed a single mathematical framework that explains the unusual rhythmic behavior of breather laser pulses. The breakthrough unites two previously separate regimes of laser dynamics for the first time.
Researchers at EPFL have created the first chip-scale ultrafast laser that matches the performance of traditional tabletop femtosecond lasers. The device delivers pulses as short as 147 femtoseconds with energies of 1.05 nanojoules.
