Researchers document presence of quantum spin liquids, an elusive state of matter never seen before

The Harvard-MIT CUA collaboration led by Lukin, Greiner, and Vuletic reported the first experimental realization of a quantum spin liquid, a highly entangled phase of matter that eluded experimental observation for several decades.  An example of topological state, such as a spin liquid, can help in the search for reliable quantum computers. Predicted about 50...

Physicists steer chemical reactions by magnetic fields and quantum interference

Physicists in the MIT-Harvard Center for Ultracold Atoms (CUA) have developed a new approach to control the outcome of chemical reactions. This is traditionally done using temperature and chemical catalysts, or more recently with external fields (electric or magnetic fields, or laser beams). MIT CUA physicists have now added a new twist to this: They...

Reversing time for quantum-enhanced metrology

The group of Prof. Vuletic, at MIT, demonstrated that reversing the time in an atomic sensor can lead to a strongly enhanced sensitivity. With this time-reversal protocol, sensors can be operated with highly-entangled states which carry large statistical information close to the fundamental Heisenberg Limit.  Due to their fragility, these “superior” quantum states are extremely...

Searching for dark matter by probing an ultranarrow optical transition in Ytterbium

The Vuletic ion lab at MIT has been searching for new dark matter candidates by measuring small shifts between atomic transition frequencies in different isotopes of Ytterbium. Measuring shifts on at least two transitions allows the researchers to plot the data in a “King Plot”, which can reveal the presence of both higher-order nuclear physics...

Sensor based on quantum physics could detect SARS-CoV-2 virus

A novel approach to testing for the presence of the virus that causes Covid-19 may lead to tests that are faster, less expensive, and potentially less prone to erroneous results than existing detection methods. Though the work, based on quantum effects, is still theoretical, these detectors could potentially be adapted to detect virtually any virus,...
