The creation of powerful quantum computers requires quantum processors with millions of qubits. However, currently, the most advanced quantum processor is composed of only 1000 qubits.
This means that we’re far behind in achieving the true potential of quantum computers, and the challenge lies in controlling and connecting qubits.
Each qubit in a quantum computer works at a specific frequency. To harness the full power of a quantum system, each qubit should be controlled individually by tuning its frequency. Plus, to connect qubits, it is important to match their frequencies.
“As a quantum processor is scaled to larger numbers of qubits, being able to simultaneously achieve both of these operations for every qubit becomes very challenging,” Vanita Srinivasa, an assistant professor of Physics at the University of Rhode Island (URI), said.
However, Srinivasa and her team at URI have figured out a solution to this problem. In their new study, they propose a modular system that can overcome the challenges mentioned above and connect qubits over long distances.
