Abstract:

Color centers in diamond have become a workhorse in the field of quantum sensing, broadly defined as the use of qubit systems to measure environmental parameters. In our lab, we harness the optical and spin properties of diamond color centers to image nanoscale physical, chemical, and biological phenomena under a wide range of conditions. I will discuss ongoing progress in developing a microfluidic quantum sensing platform for nuclear magnetic resonance spectroscopy of picoliter fluid analytes. I will discuss the use of microstructured magnetic materials which concentrate magnetic flux (in analogy to optical elements) to improve the magnetic field sensitivity of diamond quantum sensors. I will also discuss recent results using color centers in diamond for super-resolution microscopy.

Biography:

Victor Acosta  is an Assistant Professor in the Dept. of Physics & Astronomy and Center for High Technology Materials at the University of New Mexico. He did his PhD research in Dmitry Budker's AMO group in the UC Berkeley Physics dept, graduating in 2011.  From 2011-2013, Victor was a postdoc in quantum photonics in Charles Santori and Ray Beausoleil's group at HP Labs. From 2013-2015, he was a research scientist at Google Life Sciences (now Verily), where he worked on nanoparticle-based molecular imaging approaches for early detection of disease. At UNM, Victor's research lies at the intersection of condensed-matter physics, quantum optics, and biomedical imaging. His lab specializes in using color centers in diamond as quantum sensors to study nanoscale magnetic phenomena in physical, chemical, and biological systems. He is also developing nanophotonic surfaces for applications ranging from few-photon optical logic to virtual reality.
