Imagine if future quantum computers could talk to each other across cities, countries, even continents without losing their spooky quantum connection. A team of researchers from the University of British Columbia (UBC) has created a device that could help us realize this future.
This device, which is just a tiny chip made of silicon, works like a universal translator, converting signals between two incompatible energies: microwaves and light. This chip can convert up to 95% of a quantum signal in both directions, and with almost zero noise.
“It’s like finding a translator that gets nearly every word right, keeps the message intact and adds no background chatter,” lead researchers Mohammad Khalifa, and a graduate research assistant at UBC’s Blusson Quantum Matter Institute, said.
Khalifa and his team suggest that this innovation could one day unlock the dream of a quantum internet, making information transfer more secure, faster, and much more powerful than anything we have today.
