Implications for quantum computing and spintronics materials
Kobe University quantum solid state physicist FUSEYA Yuki proved that the surface of bismuth masks the fact that the bulk material is not “topological,” a property valuable for a material’s…
A new study provides insights into cleaning up noise in quantum entanglement
Researchers found that no universal entanglement purification protocol is guaranteed to improve fidelity of entangled states in all possible quantum systems. Credit: Zhong Lab Quantum entanglement—a connection between particles that…
