Para ilmuwan telah mengembangkan chip kuantum yang mengubah kebocoran foton yang tidak terkendali menjadi sinyal yang dapat dikendalikan. Pendekatan ini memungkinkan pelacakan informasi kuantum yang hilang melalui kebocoran terukur yang disengaja.
Sebuah chip kuantum baru telah diciptakan untuk mengatasi tantangan dalam mengelola kebocoran foton selama eksperimen. Chip ini mengubah kebocoran yang tidak beraturan menjadi sinyal yang dapat dikontrol dan dipantau secara efektif oleh para peneliti.
Researchers from Kyoto University and Hiroshima University have created a new technique to identify W states, a complex form of quantum entanglement. The advance could support progress in quantum computing and communication.

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.
Researchers at New York University have developed a method to direct the assembly of microscopic particles into crystals using light. This technique, detailed in the journal Chem, allows for real-time control over crystal growth and dissolution. The approach could enable new responsive materials for applications in optics and photonics.

Two recent studies indicate quantum computers could crack elliptic curve cryptography—securing banks, internet traffic, and cryptocurrencies like Bitcoin—with far fewer qubits than previously estimated: around 10,000-30,000 for one approach or 500,000 for another. Researchers highlight rapid hardware progress, urging a shift to post-quantum standards.
Researchers at East China Normal University have developed a new imaging technique that captures ultrafast events in trillionths of a second, revealing both brightness and structural changes in a single shot. The method, called compressed spectral-temporal coherent modulation femtosecond imaging (CST-CMFI), tracks phenomena like plasma formation and electron movement. Yunhua Yao, the team leader, described it as a major advance for physics, chemistry, and materials science.
