A quantum sensor for nanoscale electron transport

The word “defect” doesn’t usually have a good connotation--often indicating failure. But for physicists, one common defect known as a nitrogen-vacancy center (NV center) has applications in both quantum information processing and ultra-sensitive magnetometry, the measurement of exceedingly faint magnetic fields. In an experiment, recently published in Science, JQI Fellow Vladimir Manucharyan and colleagues at Harvard University used NV ...

Sharper Nanoscopy

A new study from Edo Waks' group has shown how to sharpen nanoscale microscopy (nanoscopy) even more by better locating the exact position of the light source. The improvement involves taking into account the phantom dipole induced in the surface of a nanowire by the presence of a nearby quantum dot. The interference of light emitted by the dot with light emitted (in effect) by the phantom distorts the estimation of the dot's true location.

Modular Entanglement Using Atomic Ion Qubits

JQI researchers, under the direction of Christopher Monroe have demonstrated modular entanglement between two atomic systems, separated by one meter. Here, photons are the long distance information carriers entangling multiple qubit modules. Inside of a single module, quantized collective vibrations called phonons connect individual qubits. In the latest result, one module contains ...

Novel Phases for Bose Gases

Strongly correlated electronic systems, like superconductors, display remarkable electronic and magnetic properties, and are of considerable research interest. These systems are fermionic, meaning they are composed of a class of particle called a fermion. Bosonic systems, composed another family of particles called bosons, offer a level of control often not possible in solid ...

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.

Greater magnetic sensitivity is also useful in many scientific areas, such as the identification of ...

Michelson-Morley Experiment for Electrons

 A new experiment conducted at the University of California at Berkeley used quantum information techniques for a precision test of a cornerstone principle of physics, namely Lorentz invariance.  This precept holds that the results of a physics experiment do not depend on its absolute spatial orientation.  The work uses quantum-correlated electrons within a pair of calcium ions to look for ...
