An ultrafast optical technique uncovers new clues to the origin of bulk polarization in quantum ferroelectric materials.

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 ...

Photoelectron interference can reveal otherwise hidden properties of quantum light through an apparent attosecond time shift.

A new device in which more than 600 atoms are manipulated within a single optical cavity could allow for the scaling up of neutral-atom quantum computers. Neutral-atom arrays are a leading platform ...

Regions within a cell in which biomolecules are concentrated, called condensates, form different structures when enzymes are involved, according to experiments. A biomolecular condensate is a small ...

When intense quantum light knocks electrons out of atoms, the statistics of the light can be transferred to the electrons. Strong-field ionization—a process in which intense laser light strips ...

Two independent teams have built operating nuclear clocks—devices that might one day rival the best atomic clocks and offer new ways to probe fundamental physics. Photograph of the thorium-229-doped ...

Pairing superconducting qubits with microwave cavities could reduce the hardware requirements for quantum simulations of fundamental physics. Performing simulations of quantum systems on an ordinary ...
