Researchers Build an Ultrafast Quantum Battery

Quantum batteries are a new class of energy storage devices that operate according to the principles of quantum physics, the science that studies the infinitely small where the laws of classical physics do not always apply.

Spin Qubits can be Potentially Useful for Quantum Networks that Employ Optical Fibers

Quantum computers may be able to solve science problems that are impossible for today's fastest conventional supercomputers. Quantum sensors may be able to measure signals that cannot be measured by today's most sensitive sensors. Quantum bits (qubits) are the building blocks for these devices.

Experimental Realization of Atom-Optically Synthetic Gauge Field for a Noninteracting Bose Gas

Gauge fields describe the basic interactions between charged particles and are responsible for various emergent topological phases of matter. This concept recently has been further generalized to charge neutral systems by engineering an analog Hamiltonian that governs the effective dynamics of neutral particles subject to magnetic fields.

Novel Technique to Simulate Light-Matter Interactions at the Atomic Scale

Light–matter interactions form the basis of many important technologies, including lasers, light-emitting diodes (LEDs), and atomic clocks. However, usual computational approaches for modeling such interactions have limited usefulness and capability. Now, researchers from Japan have developed a technique that overcomes these limitations.

Generating Ultrashort THz Waveforms from Shifting Electrons in Asymmetric Quantum Wells

A time-dependent electric current emits an electromagnetic wave, a basic physical effect exploited in telecom antennas. Transferring this mechanism to the ultrashort length and time scales of the quantum world allows for generating intense picosecond terahertz (THz) pulses in asymmetric semiconductor quantum structures.
