Quantum research gets a boost at CINT

Sandia Labs News Release (10/24/18)
San Francisco Chronicle (10/24/18)
Washington Times (10/25/18)

Ed Bielejec examines a material at the Ion Beam Laboratory with the Nano-Implanter, a machine that produces very precise material defects.The Department of Energy has awarded Sandia and Los Alamos national laboratories $8 million for quantum research — the study of the fundamental physics of all matter — at CINT. The award will fund two three-year projects enabling scientists at the two labs to build advanced tools for nanotechnology research and development. Because of the collaborative nature of CINT, the awards also will provide opportunities for researchers outside the labs to benefit from the new technologies.

Chemical selection of emission state configuration in a quantum-light emitter

LANL Science Brief (09/06/18)

The unique symmetry of the physical structure of zigzag nanotubes (right) leads to a narrowed emission wavelength range from defect states introduced by covalent aryl functionalization. This is critical for applications in quantum information processing.CINT researchers and their collaborators have found a new way to control quantum-light emitters using so-called zigzag nanotube structures. Their work is published in the latest edition of Nature Chemistry. Stephen Doorn said, "Our effort at LANL has been advancing the development of chemically controlled defects in carbon nanotubes as room-temperature single photon emitters. These are of significant interest for enabling new optical approaches to quantum information processing. Our latest work aims to address how to control and narrow the emission wavelength range through control of functionalization chemistry."

Tuning terahertz beams with nanoparticles

BES Science Highlight (09/05/18)

The image shows the different magnetic and electric effects that occur in the cobalt ferrite (CFO) core (square) and surrounding barium titanate (BTO) shell (sphere) when an assembly of nanoparticles is operated in an external magnetic field (B). The direction of the applied magnetic field with respect to the terahertz beam leads to amplitude (antiparallel B) and phase (parallel B) modulation of a transmitted terahertz pulse via the magneto-elasto-electric (MEE) effect. The applied magnetic field produces a surface polarization charge density ssb on the nanoparticle shell.CINT scientists and their collaborators have uncovered a way to control terahertz radiation using tiny engineered particles in a magnetic field. By controlling the strength and direction of the applied magnetic field, the nanoparticles dynamically tuned a terahertz beam’s phase and amplitude. This research potentially opens the doors for better medical and environmental sensors.

Carbon nanotubes give two excitons for the price of one

BES Science Highlight (09/05/18)

In a carbon nanotube (top, gray cylinder), the capture of a photon (green arrow) generates two excitons (blue and red spheres bound together) at oxygen doping sites (top, red balls). The excitons recombine and emit photon pairs (bottom, pink stars).CINT scientists have identified how modified carbon nanotubes emit photon pairs. The experiments and theory show that the photon pairs are the result of the capture and recombination of two excitons (electron–hole pairs). This efficient generation of photon pairs from modified carbon nanotubes shows a path to new types of light sources.

Progress toward plugging an antibiotic pump

Sandia Labs News Release (08/03/18)

Susan Rempe stands in front of the Center for Integrated Nanotechnologies, where some of her research on bacterial pumps was done.Each year in the U.S., at least 23,000 people die from infections caused by antibiotic-resistant bacteria. One way bacteria develop resistance to many different antibiotics is by producing pumps that spit out unfamiliar small molecules, such as antibiotics, before they can do any damage. The researchers teased out the details of how one antibiotic pump works. This project made extensive use of Sandia’s high-performance computing resources and was conducted at CINT.

Coherent exciton-vibrational dynamics and energy transfer in conjugated organics

LANL Science Brief (07/03/18)

Coherent electron-vibrational dynamics can appear after so-called non-radiative relaxation when instead of emitting as light, electronic energy is transferred to vibrations or heat. In a new theoretical study described in a Nature Communications paper, CINT scientist Sergei Tretiak and collaborators demonstrate the appearance of coherent electron-vibrational dynamics after so-called non-radiative relaxation. The effect appears as a ‘sloshing’ of electron density back and forth between molecular sites.

Light mixer generates 11 colors simultaneously

Sandia Labs News Release (06/28/18)

Sandia National Laboratories postdoctoral appointee Polina Vabishchevich, left; and Senior Scientist Igal Brener work in their optics lab.Research by CINT scientists Igal Brener and John Reno and their collaborators shows how a metamaterial made up of an array of nanocylinders mixes two laser pulses of near infrared light to produce 11 waves of light. The light ranges in color from the near infrared, through the colors of the rainbow, to ultraviolet. This work was published in Nature Communications. Igal says, "Without CINT's specialized femtosecond laser system, it would have been very challenging to perform these measurements."

A bit of quantum logic

BES Science Highlight (06/18/18)

Angled view scanning electron microscope image of the device gate structure.Quantum computers could tackle problems that current supercomputers can’t. Quantum computers rely on quantum bits, or "qubits," which represent data by the binary state of electron spins. Two systems existed to create qubits—donor atoms and quantum dots. CINT researchers and collaborators have successfully integrated the systems. This hybrid approach, which has remained elusive until now, exploits the advantages of the two qubit systems.
