NTT: Realization of Modularized Quantum Light Source Toward Fault-tolerant Large-scale Universal Optical Quantum Computers

NTT Corporation in cooperation with the University of Tokyo (President: Teruo Fujii, Bunkyo-ku, Tokyo) and RIKEN has developed an optical fiber-coupled quantum light source (squeezed light source), which is a key technology for realizing a fault-tolerant large-scale universal optical quantum computer.

Novel Tool for Investigating the Quantum Characteristics of ‘Combs’ of Light

Unlike the jumble of frequencies produced by the light that surrounds us in daily life, each frequency of light in a specialized light source known as a "soliton" frequency comb oscillates in unison, generating solitary pulses with consistent timing.

QUEST Researchers Move Closer to Developing More Accurate Optical Atomic Clocks

Laser beams can do more than just heat things up; they can cool them down too. That is nothing new for physicists who have devoted themselves to precision spectroscopy and the development of optical atomic clocks.

Researchers Predict the Existence of Split Photons

Nearly a century after Italian physicist Ettore Majorana laid the groundwork for the discovery that electrons could be divided into halves, researchers predict that split photons may also exist, according to a study from Dartmouth and SUNY Polytechnic Institute researchers.

Synchronisation is More Readily Achieved in Many Systems than Previously Thought

Physicists from Trinity College Dublin have unlocked the secret that explains how large groups of individual "oscillators" – from flashing fireflies to cheering crowds, and from ticking clocks to clicking metronomes – tend to synchronise when in each other's company.
