This is a quantum sensing hardware result: NV-center diamond magnetometers reaching 48 MHz single-resonance bandwidth, roughly tenfold over prior work, at a stated sensitivity of 548 pT/√Hz. The claimed communications applications are prospective and not demonstrated here, so readers should treat them as motivation rather than results. Quantum sensing isn't a listed category, so this is the closest fit among the quantum options.
Researchers Measure 48mhz-Bandwidth Quantum Sensor Using Diamond
Expanding detection beyond MHz scales has long limited quantum sensors’ potential for high-speed communications. Now, techniques leveraging multiple microwaves under a magnetic gradient push diamond nitrogen-vacancy (NV) center bandwidth to 48MHz, over an order of magnitude increase compared to previous limitations. This advance achieves sensitivities down to $8.
A breakthrough at Monash University has expanded the bandwidth of magnetic quantum sensors using diamonds containing nitrogen vacancy centres. Limitations in sensing bandwidth previously restricted their use; however, a single resonance bandwidth of forty-eight MHz was achieved, over ten times greater than before. This result came from strong driving with multiple modulated microwave fields under a magnetic gradient, alongside sensitivity down to five hundred…
