phononic links

A proposed chip architecture from the University of Warwick and Canada’s National Research Council could address a central scaling problem for semiconductor quantum computers: connecting qubits that are far apart without adding a separate interconnect layer. The concept, called Quantum Phononic...

A new APL Quantum paper from the University of Warwick and Canada’s National Research Council outlines a way to connect distant semiconductor qubits using engineered vibrations inside the chip itself. The proposed Quantum Phononic Links, or QPLs, could offer a more fabrication-friendly route...
