Significant new discovery in teleportation research : Noise can improve the quality of quantum teleportation

2 mai

Researchers have succeeded in conducting an almost perfect quantum teleportation despite the presence of noise that usually disrupts the transfer of quantum state. The results have been published in the journal Science Advances.

Research demonstrates high qubit control fidelity and uniformity in single-electron control

2 mai

The journal Nature has published a research paper, "Probing single electrons across 300-mm spin qubit wafers," demonstrating state-of-the-art uniformity, fidelity and measurement statistics of spin qubits. The industry-leading research opens the door for the mass production and (…)

Researchers find unexpected roadblock to conductivity in Mott insulators

2 mai

In the realm of condensed matter physics, few phenomena captivate physicists’ curiosity as much as Mott insulators. According to traditional theory, this odd class of materials should be capable of conducting electricity, yet they behave mostly as insulators.

Twisting and binding matter waves with photons in a cavity

2 mai

Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom "recoils" in the opposite direction, making it difficult to measure the position and momentum of the atom (…)

High-intensity spatial-mode steerable frequency up-converter toward on-chip integration

1er mai

A study published in Opto-Electronic Science discusses high-intensity spatial-mode steerable frequency up-converter toward on-chip integration.

Researchers build new device that is a foundation for quantum computing

1er mai

Scientists led by the University of Massachusetts Amherst have adapted a device called a microwave circulator for use in quantum computers, allowing them for the first time to precisely tune the exact degree of nonreciprocity between a qubit, the fundamental unit of quantum computing, and a (…)

New work reveals the ’quantumness’ of gravity

1er mai

Gravity is part of our everyday life. Still, the gravitational force remains mysterious : to this day we do not understand whether its ultimate nature is geometrical, as Einstein envisaged, or governed by the laws of quantum mechanics.

CERN gives green light to build new experiment to search for unknown particles

1er mai

After many years of preparations, CERN has approved a new experiment : the Search for Hidden Particles (SHiP). Physicist Alexey Boyarsky was involved from the start. "We know there is physics that’s missing and we aim to find it."

Generating graph states of atomic ensembles via photon-mediated entanglement

1er mai

Graph states, a class of entangled quantum states that can be represented by graphs, have been the topic of numerous recent physics studies, due to their intriguing properties. These unique properties could make them particularly promising for quantum computing applications, as well as a wider (…)

Physicists discover new way to make strange metal

1er mai

By tinkering with a quantum material characterized by atoms arranged in the shape of a sheriff’s star, MIT physicists and colleagues have unexpectedly discovered a new way to make a state of matter known as a strange metal. Strange metals are of interest for their unusual physics and because (…)
