Quantum technologies take advantage of the strange world of quantum mechanics where, for example, objects can exist in two places at once. This world typically occurs on the atomic level at low temperatures which has meant that technologies that exploit these properties have been challenging to manufacture. Recent work has demonstrated that the quantum mechanical properties of impurities that have been added to a synthetic diamond can be controlled simply by shining light on the diamond and measuring light that is emitted, even at room temperature. These ‘quantum defects ‘ have the potential to be used for a range of applications such as measuring the magnetic fields on the nanoscale, which may revolutionise biology, or forming a quantum computer which has the potential to solve problems no current computer can. Critical to the development of these technologies is to have the impurities close to the surface of the diamond but retaining their unique quantum properties. This projects objective is develop a low damage diamond polishing technique which is compatible with these quantum defects retaining their properties within 50 nm of the surface.

量子技术利用了量子力学的奇异世界，例如，物体可以同时存在于两个地方。这个世界通常发生在低温下的原子水平上，这意味着利用这些特性的技术在制造上具有挑战性。最近的工作表明，添加到合成金刚石中的杂质的量子力学性质可以简单地通过在金刚石上照射光并测量发射的光来控制，即使在室温下也是如此。这些“量子缺陷”有可能被用于一系列应用，例如测量纳米尺度上的磁场，这可能会彻底改变生物学，或者形成一台量子计算机，它有可能解决目前计算机无法解决的问题。发展这些技术的关键是使杂质接近金刚石表面，但保留其独特的量子特性。该项目的目标是开发一种低损伤的金刚石抛光技术，该技术与这些量子缺陷兼容，并在50 nm的表面范围内保持其特性。
