Researchers at The University of Tokyo and RIKEN achieved 73% Bell-state fidelity across a 30 MHz bandwidth using broadband transfer resonators, eliminating the need for complex circuit tuning. This architecture simplifies control lines and noise management, offering a scalable pathway for deterministic quantum communication between fixed-frequency superconducting qubits. The approach effectively addresses sender-receiver frequency mismatches, advancing the feasibility of robust, interconnected quantum networks.

Researchers achieved deterministic quantum communication & remote entanglement between superconducting qubits, reaching 73% Bell-state measurement.
A Bell-state fidelity of 73 percent has been achieved in quantum communication across a 30 MHz frequency range, a relatively high number given the difficulties of maintaining entanglement between distant qubits. Researchers led by Takeaki Miyamura at The University of Tokyo and RIKEN Center for Quantum Computing demonstrated deterministic quantum…
