A team led by scientists and engineers at the University of Washington has announced a significant advancement in developing fault-tolerant qubits for quantum computing. In a pair of papers published June 14 in Nature and June 22 in Science, they report that, in experiments with flakes of semiconductor materials — each only a single layer of atoms thick — they detected signatures of “fractional quantum anomalous Hall” (FQAH) states. The team’s discoveries mark a first and promising step in constructing a type of fault-tolerant qubit because FQAH states can host anyons — strange “quasiparticles” that have only a fraction of an electron’s charge. Some types of anyons can be used to make what are called “topologically protected” qubits, which are stable against any small, local disturbances.
Scientists at the University of Washington are pursuing multiple quantum research projects spanning from creating materials with never-before-seen physical properties to studying the “quantum bits” — or qubits (pronounced “kyu-bits”) — that make quantum computing possible. UW News sat down with Professor Kai-Mei Fu, one of the leaders in quantum research on campus, to talk about the potential of quantum R&D, and why it’s so important.
Seven professors at the University of Washington are among 25 new members of the Washington State Academy of Sciences for 2022, according to a July 15 announcement.
Researchers have discovered that light — from a laser — can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electrons “spins,” which have a potential applications in quantum computing. Scientists discovered that electrons within the material became oriented in the same direction when illuminated by photons from a laser. By controlling and aligning electron spins at this level of detail and accuracy, this platform could have applications in quantum computing, quantum simulation and other fields. The experiment, led by scientists at the University of Washington, the University of Hong Kong and the Pacific Northwest National Laboratory, was published April 20 in Nature.

In a paper published Sept. 14 in the journal Nature Physics, a team led by the University of Washington reports that carefully constructed stacks of graphene — a 2D form of carbon — can exhibit highly correlated electron properties. The team also found evidence that this type of collective behavior likely relates to the emergence of exotic magnetic states.

A team of chemical engineers has developed a new way to produce medicines and chemicals and preserve them using portable “biofactories” embedded in water-based gels known as hydrogels. The approach could help people in remote villages or on military missions, where the absence of pharmacies, doctor’s offices or even basic refrigeration makes it hard to access critical medicines and other small-molecule compounds. The team — led by Hal Alper, a professor of chemical engineering at the University of Texas, and…

Scientists have designed and tested an experimental system that uses a near-infrared laser to actively heat two gold nanorod antennae — metal rods designed and built at the nanoscale — to different temperatures. The nanorods are so close together that they are both electromagnetically and thermally coupled. Yet the team measured temperature differences between the rods as high as 20 degrees Celsius and could change which nanorod was cooler and which was warmer, even though the rods were made of the same material.
Scientists have visualized the electronic structure in a microelectronic device for the first time, opening up opportunities for finely tuned, high-performance electronic devices.

Six University of Washington professors are to receive a Presidential Early Career Award for Scientists and Engineers, according to an announcement July 2 from the White House.

In a paper published May 20 in the journal Nature Materials, a team of researchers from the University of Washington unveiled a new strategy to keep proteins intact and functional in synthetic biomaterials for tissue engineering. Their approach modifies proteins at a specific point so that they can be chemically tethered to the scaffold using light. Since the tether can also be cut by laser light, this method can create evolving patterns of signal proteins throughout a biomaterial scaffold to grow tissues made up of different types of cells.

Drug treatments can save lives, but sometimes they also carry unintended costs. After all, the same therapeutics that target pathogens and tumors can also harm healthy cells. To reduce this collateral damage, scientists have long sought specificity in drug delivery systems: A package that can encase a therapeutic and will not disgorge its toxic cargo until it reaches the site of treatment — be it a tumor, a diseased organ or a site of infection. In a paper published Jan….
