Cientistas desenvolveram um chip quântico que converte vazamentos de fótons não controlados em sinais controláveis. A abordagem permite o rastreamento de informações quânticas perdidas por meio de vazamentos deliberados e controlados.
Um novo chip quântico foi criado para enfrentar os desafios no gerenciamento de vazamentos de fótons durante experimentos. Ele transforma vazamentos desordenados em sinais que pesquisadores podem controlar e monitorar de forma eficaz.
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.
