Improving broadband displacement detection with quantum correlations
N. S. Kampel, R. W. Peterson, R. Fischer +5
Interferometers enable ultrasensitive measurement in a wide array of applications from gravitational wave searches to force microscopes. The role of quantum mechanics in the metrol…
Local probing of nuclear bath polarization with a single electronic spin
Paz London, Ran Fischer, Ignacio Alvizu +2
We demonstrate experimentally that a polarized nuclear spin modifies the dynamic behavior of a neighboring electronic spin. Specifically, an out-of-phase component appears in the e…
Local and bulk 13C hyperpolarization in NV-centered diamonds at variable fields and orientations
Gonzalo A. Alvarez, Christian O. Bretschneider, Ran Fischer +6
Polarizing nuclear spins is of fundamental importance in biology, chemistry and physics. Methods for hyperpolarizing 13C nuclei from free electrons in bulk, usually demand operatio…
Time-Optimal Universal Control of Two-Level Systems under Strong Driving
Chen Avinadav, Ran Fischer, Paz London +1
We experimentally study the time-optimal construction of arbitrary single-qubit rotations under a single strong driving field of finite amplitude. Using radiation-dressed states of…
Detecting and polarizing nuclear spins with double resonance on a single electron spin
P. London, J. Scheuer, J. -M. Cai +11
We report the detection and polarization of nuclear spins in diamond at room temperature by using a single nitrogen-vacancy (NV) center. We use Hartmann-Hahn double resonance to co…
Bulk Nuclear Polarization Enhanced at Room-Temperature by Optical Pumping
Ran Fischer, Christian O. Bretschneider, Paz London +3
Bulk 13C polarization can be strongly enhanced in diamond at room-temperature based on the optical pumping of nitrogen-vacancy color centers. This effect was confirmed by irradiati…
Optical polarization of nuclear ensembles in diamond
Ran Fischer, Andrey Jarmola, Pauli Kehayias +1
We report polarization of a dense nuclear-spin ensemble in diamond and its dependence on magnetic field and temperature. The polarization method is based on the transfer of electro…
