Purdue ­niversity researchers used qudits to develop what could be a quantum version of a transistor, known as a gate.

Qubits exist only in superpositions of 0 and 1 states, while qudits exist in multiple states, such as 0 and 1 and 2, meaning that more data can be encoded and processed.

The new gate would be inherently more efficient than qubit gates, but it would also be more stable because the researchers packed the qudits into photons, which are not easily disturbed.

The gate creates one of the largest entangled states of quantum particles ever achieved.

Said Purdue researcher Andrew Weiner, "This gate allows us to manipulate information in a predictable and deterministic way, which means that it could perform the operations necessary for certain quantum information processing tasks."
