Topological superconductors hold promise for fault-tolerant quantum computing, but isolating signatures of the desired ...

A device that stores a single positron and controls its quantum states could measure its magnetic moment with unprecedented precision, testing a symmetry principle central to quantum field theory.

According to the Heisenberg uncertainty principle, both the position and momentum of a quantum particle cannot be known with unlimited precision. In 1965, theorists showed that this principle does not ...

Conduction electrons typically whiz through crystals in broad energy bands. However, some arrangements of atoms conceivably engender so much destructive interference among the electrons’ wave packets ...

Figure 1: Moore and his colleagues measured the momentum kick imparted by a single gas molecule on an optically levitated silica nanoparticle (center) [2]. Thanks to the isolation offered by setups ...

A technique known as ghost imaging has been adapted so that an object can be imaged by discarding all photons that interact with it. Split a beam of light in two and direct one beam (the reference) to ...

An ultrafast optical technique uncovers new clues to the origin of bulk polarization in quantum ferroelectric materials. In classical ferroelectric materials, electric dipoles in the material line up ...

Figure 1: Among the key ingredients necessary to derive the Born rule, Zhang observes that additivity is indispensable in existing derivations. Figure 1: Among the key ingredients necessary to derive ...

Zhou and his colleagues considered a well-established technique known as reconstruction of attosecond beating by interference of two-photon transitions (RABBIT). In RABBIT, a train of ...
