Quantum computing systems, computer systems that are based on the key principles of quantum theory, could significantly outperform conventional computing systems, both in terms of speed and performance. Over the past decade or so, many […]

A team of researchers affiliated with several institutions in Germany and two in France has set a new record for the coldest temperature ever recorded in a lab setting—38 picokelvins. In their paper published in […]
In 1998, researchers including Mark Kubinec of UC Berkeley performed one of the first simple quantum computations using individual molecules. They used pulses of radio waves to flip the spins of two nuclei in a […]
Quantum technology typically employs qubits (quantum bits) consisting of, for example, single electrons, photons or atoms. A group of TU Delft researchers has now demonstrated the ability to teleport an arbitrary qubit state from a […]
The fundamental forces of physics govern the matter comprising the universe, yet exactly how these forces work together is still not fully understood. The existence of Hawking radiation—the particle emission from near black holes—indicates that […]
Levitation of both large objects and of single atoms has become a widely used technique in science and engineering. In the last years, many researchers have started to explore a new horizon: the levitation of […]
Spin torque provides convenient electric means to efficiently control magnetizations. It can usually be produced by spin-polarized current or pure spin current via spin Hall effect. The former and the latter are named as spin […]
The quantum behavior of atomic vibrations excited in a crystal using light pulses has much to do with the polarization of the pulses, say materials scientists from Tokyo Tech. The findings from their latest study […]
Researchers at the National Institute of Standards and Technology (NIST) and collaborators have devised and tested a new, highly sensitive method of detecting and counting defects in transistors—a matter of urgent concern to the semiconductor […]
Countless astrophysicists and astronomers are actively searching for unobserved celestial bodies in the universe, as detecting these bodies could improve our understanding of space and help to address unanswered astrophysical questions. Among these elusive objects […]
