Diamonds Shine a Light on Hidden Currents in Graphene

It sounds like pure sorcery: using diamonds to observe invisible power swirling and flowing through carefully crafted channels. But these diamonds are a reality. JQI Fellow Ronald Walsworth and Quantum Technology Center (QTC) Postdoctoral Associate Mark Ku, along with colleagues from several other institutions, including Professor Amir Yacoby and Postdoctoral Fellow Tony Zhou at Harvard, have developed a way to use diamonds to see the elusive details of electrical currents.

Microfluidic Diamond Sensor

Measuring faint magnetic fields is a trillion-dollar business.  Gigabytes of data, stored and quickly retrieved from chips the size of a coin, are at the heart of consumer electronics.   Even higher data densities can be achieved by enhancing magnetic detection sensitivity---perhaps down to nano-tesla levels.
