Quantum Physicists Achieve Full Entanglement of Two Digits

Physicists at the University of Innsbruck have fully entangled two qudits, each encoded in up to 5 states of individual Calcium ions, paving the way for more efficient and powerful quantum computers. The challenge for qudit-based quantum computers has been to efficiently create entanglement between the high-dimensional information carriers. This breakthrough could lead to faster and more robust quantum computers, moving beyond binary information processing.
