DC Magnetometry at the T2 Limit
Sensing static or slowly varying magnetic fields with high sensitivity and spatial resolution is critical to many applications in fundamental physics, bioimaging and materials science. Several versatile magnetometry platforms have emerged over the past decade, such as electronic spins associated with Nitrogen Vacancy (NV) centers in diamond. However, their high sensitivity to external fields al...
متن کاملAncilla-assisted quantum process tomography.
Complete and precise characterization of a quantum dynamical process can be achieved via the method of quantum process tomography. Using a source of correlated photons, we have implemented several methods, each investigating a wide range of processes, e.g., unitary, decohering, and polarizing. One of these methods, ancilla-assisted process tomography (AAPT), makes use of an additional "ancilla ...
متن کاملLinear-Assisted DC-DC Switching Converter with Constant Switching Frequency
This article shows the proposal of a linear–assisted converter or linear–&–switching hybrid converter with a constant switching frequency. The control loop of the system is based on the current–mode technique. The main disadvantage of a converter with current–mode control is the inherent instability of the loop when switch duty ratios are greater than 0.5. In order to make stable the proposed l...
متن کاملNanoscale magnetometry: Microscopy with single spins.
S cientists have been searching for tools that are sensitive enough to measure the faint magnetic moment of a single electronic or nuclear spin for decades. Because many chemical elements carry a nuclear magnetic moment, a technique that could routinely image nuclear magnetism on the nanometre scale would allow researchers to extract useful information from materials, such as the chemical ident...
متن کاملAncilla-assisted discrimination of quantum gates
The intrinsic idea of superdense coding is to find as many gates as possible such that they can be perfectly discriminated. In this paper, we consider a new scheme of discrimination of quantum gates, called ancillaassisted discrimination, in which a set of quantum gates on a d−dimensional system are perfectly discriminated with assistance from an r−dimensional ancilla system. The main contribut...
