Para fisikawan telah menerbitkan penelitian yang mengusulkan bahwa satu jam dapat berdetak lebih cepat dan lebih lambat secara bersamaan akibat efek kuantum. Karya ini menggabungkan relativitas dan mekanika kuantum dengan cara yang baru. Para peneliti mengatakan kemajuan dalam teknologi jam atom mungkin akan segera memungkinkan gagasan tersebut diuji di laboratorium.

Sebuah makalah yang diterbitkan pada 20 April 2026 di Physical Review Letters menguraikan kemungkinan jam yang berada dalam superposisi kuantum. Asisten Profesor Igor Pikovski dari Stevens Institute of Technology memimpin studi tersebut bersama para kolaborator dari Colorado State University dan National Institute of Standards and Technology. Penelitian ini dikembangkan berdasarkan gagasan-gagasan awal dari lebih dari satu dekade lalu yang sebelumnya terlalu sulit untuk diamati.

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 uncover tiny flaw in time from quantum collapse models

An international team of physicists has found that quantum collapse models, potentially linked to gravity, introduce a minuscule uncertainty in time itself. This sets a fundamental limit on clock precision, though far below current detection levels. The research, published in Physical Review Research, explores ties between quantum mechanics and gravity.

Quantum systems exhibit memory depending on perspective, scientists find

An international team of researchers has discovered that quantum systems can appear memoryless from one viewpoint while retaining memory from another. The finding, based on Schrödinger and Heisenberg pictures, reveals hidden memory effects in quantum dynamics. This could impact the design of quantum technologies.

Scientists teleport photon state across 270 meters

Jumat, 01 Mei 2026 Dilaporkan oleh AI

An international team of researchers has achieved a milestone in quantum communication by teleporting the polarization state of a single photon between two separate quantum dots over a 270-meter open-air link. The experiment, conducted at Sapienza University of Rome, demonstrates the potential for quantum relays in future quantum networks. The findings were published in Nature Communications.
