"Using Mechanical Inputs to Enhance Quantum States in Sensors"

Most people might tend to think of diamonds as high-end adornments. UC Santa Barbara physicist Ania Bleszynski Jayich thinks of the diamonds she grows in the UC Quantum Foundry, which she co-directs, as the potentially powerful source driving quantum sensors.

Most people might tend to think of diamonds as high-end adornments. UC Santa Barbara physicist Ania Bleszynski Jayich thinks of the diamonds she grows in the UC Quantum Foundry, which she co-directs, as the potentially powerful source driving quantum sensors. Sensors are currently much farther along in their development than other potential quantum applications. Diamond sensors are particularly promising as a quantum application, because they require relatively few quantum bits (qubits) to operate, whereas a quantum computer, for instance, requires more than one hundred thousand, and perhaps as many as a million, qubits to handle error correction, one of the main hurdles for quantum computing.

Now, another advance has developed in the Bleszynski Jayich lab. An article about it, titled “Spin-embedded diamond optomechanical resonator with a mechanical quality factor exceeding one million,” appears in the March 20 issue of the journal Optica.
