A quantum circuit. Credit: Aalto University Simulation of non-Hermitian quantum mechanics using a quantum computer goes beyond centuries-old conventions. Aalto researchers have used an IBM quantum computer to explore an overlooked area of physics, and have challenged 100-year-old cherished notions about information at the quantum level. The rules of quantum […]

In a study published in Physical Review Letters, the team led by academician GUO Guangcan from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) made progress in high dimensional quantum teleportation. The researchers demonstrated the teleportation of high-dimensional states in a three-dimensional six-photon system. […]

Researchers at JQI have discovered a quantum system that is a hybrid of order and chaos.   ANIMATION Normally the word “chaos” evokes a lack of order: a hectic day, a teenager’s bedroom, tax season. And the physical understanding of chaos is not far off. It’s something that is extremely difficult […]

ANIMATION By adding some magnetic flair to an exotic quantum experiment, physicists produced an ultra-stable one-dimensional quantum gas with never-before-seen “scar” states – a feature that could someday be useful for securing quantum information. As the story goes, the Greek mathematician and tinkerer Archimedes came across an invention while traveling […]

Quantum particles lined up in a lattice form the basis for an error-tolerant quantum processor. Credit: Uni Innsbruck/Harald Ritsch Even computers can miscalculate. Already small disturbances change stored information and corrupt results. That is why computers use methods to continuously correct such errors. In quantum computers, the vulnerability to errors […]

A team led by Princeton physicists discovered a surprising quantum phenomenon in an atomically thin insulator made of tungsten ditelluride. The results suggest the formation of completely new types of quantum phases previously hidden in insulators.

Atoms are trapped in an optical cavity composed of two mirrors. When a “squeezing” laser is set through the cavity, the atoms are entangled, and their frequency is measured with a second laser, as a platform for more precise atomic clocks. Credit: courtesy of the researchers The new atomic clock […]
