MIT’s ‘remote entanglement’ discovery lets QPUs to communicate at vast distances

Researchers have created a device that allows quantum processors to communicate with each other directly — an important step in developing practical quantum computers . It could mean both faster and less error-prone communication between processors. Existing quantum architecture offers only limited communication between separate quantum processing units (QPUs). Such communication is “point-to-point,” meaning that information has to be transferred in a chain across several nodes before reaching its destination. This increases the possibility of exposing the quantum information to noise and makes it more likely for errors to occur. However, the new device developed by MIT scientists allows for…
