Editor's noteThere are two main types of quantum chips: electronic quantum chips and photonic quantum chips. Representatives of electronic quantum chips, including Intel, which focuses on silicon spin qubits, IBM, and IMEC, which focus on superconducting qubits, are exploring the large-scale semiconductor manufacturing of quantum chips...

Science and Technology Daily (reporter Zhang Jiaxin) A few days ago, a team led by Professor Andrew Cleland of the Pritzker School of Molecular Engineering (PME) of the University of Chicago used a device called an acoustic beam splitter to "split" phonons, thereby demonstrating their quantum properties. They demonstrated that beam splitters can be used to induce a special quantum superposition state of a phonon and further generate interference between two phonons...

Science and Technology Daily, Seoul, June 4 (Reporter Xue Yan) An international joint team, including the Ulsan Institute of Science and Technology of South Korea, recently developed an original technology of "3D quantum memory", and found the phenomenon of "nano crystal bidirectional optical switch" that can control the infinite repeated flickering in photoactive nanoparticles (ANP).ANP is a material developed by the team in 2021...

Science and Technology Daily, Beijing, May 30 (Reporter Liu Xia) A superconducting quantum bit - magnetic flux quantum bit has maintained its quantum properties for about 1.48 milliseconds, which is much longer than the "life" of similar quantum bits currently favored by the quantum computing industry, and is expected to make future quantum computer more practical...
