"Qudit" Computers Go Beyond Ones and Zeroes

Quantum computers mostly depend on quantum bits or “qubits” that each can symbolize two numbers, 0 or 1. Now, in a new study, researchers have developed a quantum computer based on quantum digits or “qudits” that each can encode seven numbers. A qudit computer may prove better at tackling complex problems than qubit computers, and may unlock more computational power with fewer components.
