"Researchers Build Transistor-Like Gate for Quantum Information Processing -- with Qudits"
A quantum version of a transistor has been built by researchers at Purdue University. The transistor-like quantum gate was built with qudits to allow for the encoding and processing of more quantum information as qudits exist in multiple states. The two-qudit gate developed by researchers improves the entanglement of quantum particles, called photons. The physical principle of entangled photons serves to further secure communication between a sender and receiver from the eavesdropping or interception of listeners. This article continues to discuss the two-qudit gate in regard to how it improves the processing of quantum information as well as the next steps that will be taken in this research.
