Researchers at National Tsing Hua University (NTHU) have developed the world’s smallest box-sized quantum computer. It uses a single photon to perform quantum algorithms. The device encodes data in 32 dimensions within a photon’s wave packet, enabling efficient and stable performance at room temperature without large cooling systems.
The photonic quantum computer demonstrates prime factorization using Shor’s algorithm and promises applications in AI, data security, logistics, and drug development. Published in *Physical Review Applied*, the innovation marks a milestone in quantum technology with potential for commercial use.
