APPLICATIONS OF TECHNOLOGY:
- Quantum Computing
- Overcomes and eliminates negative effects of TLS in dielectric amorphous thin films
- Improves elastic quality and reduces noise in mechanical and quantum resonators
- Leverages industry standard physical vapor deposition platforms
The ubiquitous low-energy excitations, known as the two-level tunneling systems (TLS), are one of the universal phenomena of amorphous solids. These excitations dominate the acoustic, dielectric, and thermal properties of structurally disordered solids. TLS in dielectric amorphous thin films have become a bottleneck in an array of cutting edge technologies as they cause both elastic and dielectric losses. TLS reduce the elastic quality factor and cause noise in both mechanical and quantum resonators. To help overcome these challenges, researchers at UC Berkeley, Berkeley Lab and Naval Research Laboratory have teamed to leverage traditional vapor deposition techniques to advance new amorphous silicon materials with diminished TLS. Their results offer a simple approach for preparing low-loss dielectrics for revolutionary advances in semiconductor storage technologies.
