UC Santa Barbara physicist Ania Bleszynski Jayich is advancing diamond-based quantum sensors, leveraging lab-grown diamonds from the UC Quantum Foundry as a robust platform for near-term quantum applications.
Diamond quantum sensors require far fewer qubits than quantum computers—operating effectively with minimal qubits compared to the 100,000+ needed for error-corrected quantum computing, addressing a major technical hurdle.
The research achieves a record Q factor exceeding one million, significantly enhancing sensor sensitivity by coupling mechanical inputs to diamond qubit states, a breakthrough for precision measurements.
Unlike other quantum technologies, diamond sensors are further along in development, offering practical applications sooner in fields like magnetometry, materials science, and biomedical imaging.
This work underscores diamonds’ dual role as both a luxury material and a high-performance quantum resource, prioritizing real-world sensor deployment over distant quantum computing goals.
Summarize this article with:
Most people think of diamonds as high-end adornments.
Not Ania Bleszynski Jayich. The UC Santa Barbara physicist sees diamonds, which she grows in the UC Quantum Foundry, as a potentially powerful foundation for quantum sensors. Sensors are currently much farther along in their development than other potential quantum applications. Diamond sensors are particularly promising because diamonds require relatively few quantum bits (qubits) to operate, whereas a quantum computer, for instance, requires more than 100,000, perhaps as many as a million, qubits to handle error correction, one of the main hurdles for quantum computing.
