Taiwan’s National Tsing Hua University researchers have successfully developed the world’s smallest quantum computer, capable of performing complex algorithms using a single photon. Led by Professor Chuu Chih-sung, the team demonstrated their box-sized device’s ability to complete prime factorization according to Shor’s algorithm approach.
This breakthrough technology encodes information in 32 time-bins or dimensions within the wave packet of a single high-dimensional photon, offering lower energy costs and minimal interference during long-distance transmission. Unlike other quantum computer types that require cooler temperatures, this photonic device can maintain stable quantum states at room temperature.
National Tsing Hua University President Kao Wei-yuan hailed the achievement as a major milestone in quantum technology, while Professor Mou Chung-yu predicted widespread applications in fields such as drug development, logistics optimization, data security, and artificial intelligence.
