Quantum Electromagnetics Engineering Lab
Machine-translated · View original
The lab builds a clock that is off by only one second over the lifetime of the universe, and creates artificial atoms.
AboutAbout the lab
Ultra-precise measurement using the quantum states of atoms.
The Quantum Electromagnetics Engineering Lab studies ultra-precise measurement using the quantum states of atoms, and metamaterials, which are artificial atomic systems.
The lab is trying to use laser light to realize an atomic clock that would drift by only one second over a span of time comparable to the lifetime of the universe.
It explores new phenomena using metamaterials, which control electromagnetic waves with artificial structures, and demonstrates them with microwaves and terahertz waves. The lab approaches this through both experiment and theory.
Key terms
- Atomic clock
- A clock that keeps time very accurately by using the frequency of light or radio waves absorbed or emitted by atoms as a reference.
- Optical frequency comb
- Light made up of many frequencies lined up at regular intervals. It serves as a ruler for measuring the frequency of light.
- Metamaterial
- A material made by arranging artificial structures so that it responds to electromagnetic waves in ways that natural substances do not.
ResearchResearch themes
The lab studies ultra-high-precision atomic clocks and quantum computers based on single ions and ion arrays, optical frequency synthesizers, and metamaterials, through both experiment and theory.
*Illustrative imageThe best clock from a single ion
A single ion confined in ultra-high vacuum is brought nearly to rest by laser cooling, and the frequency of the light it absorbs is used as a reference, aiming for an ultra-high-precision optical atomic clock. The lab also works toward a quantum computer using a small number of ions in an array.
*Illustrative imageBuilding a ruler for the frequency of light
Using the optical frequency comb produced by an ultrashort-pulse laser as a ruler, the lab studies direct comparison of optical and microwave frequencies. It also aims for stable lasers at arbitrary wavelengths, more stable microwave sources, and compact atomic clocks.
*Illustrative imageControlling electromagnetic waves with artificial structures
The lab studies storage and retrieval of electromagnetic waves using metamaterials, and control of spectrum and polarization with two-dimensional metasurfaces, through both electromagnetic field simulation and microwave and terahertz experiments.
