Fiber optics couple laser light directly into the ion-trap chip. When in use, the chip is cooled to cryogenic temperatures in a vacuum chamber, and waveguides on the chip deliver the light to an ion trapped right above the chip’s surface for performing quantum computation.

Schematic diagram showing both the magnetism and the conductive behavior on the surface of MnBi2Te4. The magnetism points uniformly upward, as shown by the red arrows, and the surface electrons, represented by the hourglass structures, are conductive because the top and bottom halves touch at the vertex with no ‘gap’ […]

In a new theoretical study, Caltech physicists have shown how molecules can, in theory, be used to reduce errors in quantum computing. This strategy would involve placing a rotating molecule in “superposition,” which means that it would exist in multiple orientations at once. In this illustration, three different molecular orientations […]

Study shows the need to shield qubits from natural radiation, like cosmic rays from outer space. A multi-disciplinary research team has shown that radiation from natural sources in the environment can limit the performance of superconducting quantum bits, known as qubits. The discovery, reported today in the journal Nature, has […]

An MIT-designed miniature “squeezer” reduces quantum noise in lasers at room temperature. The marble-sized system could enable better laser precision for quantum computing and gravitational-wave detection. This illustration shows an artist’s interpretation of the system.

This graphic depicts a stylized rendering of the quantum photonic chip and its assembly process. The bottom half of the image shows a functioning quantum micro-chiplet (QMC), which emits single-photon pulses that are routed and manipulated on a photonic integrated circuit (PIC). The top half of the image shows how […]
