Taiwanese Researchers Unveil World’s Smallest Quantum Computer Using Single Photon for Quantum Algorithms and Prime Factorization.
A high-dimensional photon can encode information in “32 time-bins,” enabling the researchers’ compact quantum computer to function efficiently.At a press briefing, a group from National Tsing Hua University showcased their inventiveness. They demonstrated the use of “Shor’s algorithm” to solve prime factorization on their box-sized quantum computer.
However, photons offer a major advantage in the development of commercial quantum computers due to their extended transmission range and reduced susceptibility to interference. Because of this characteristic, quantum computers may perform complicated operations up to 100 million times quicker than traditional computers, including prime factorization and big data searches.
The device uses calcium ion-based optical qubits, in which entanglement is produced by laser pulses that change the ions’ states. According to the team, with commercially available electro-optic modulators capable of 40 GHz bandwidth, it is feasible to encode over 5,000 time-bin modes on long single photons.
Research indicates that high-dimensional states are more resistant to noise in quantum channels, making time-bin-encoded states of long single photons promising for future high-dimensional quantum computing.
