UV laser pulses selectively engineer diamond defects, leaving qubits intact

Researchers demonstrated that ultraviolet laser pulses can selectively create atomic-scale defects in diamond while leaving existing quantum qubits undisturbed. The method offers control over the optical and electronic properties of defects for quantum systems.

• UV laser pulses selectively create defects in diamond
• Existing quantum qubits remain intact during the process
• Atomic defects give diamond new optical and electronic properties
