‘Toggle Switch’ Can Help Quantum Computers Cut Through the Noise

A blue-tinged drawing shows a schematic of the two qubits and resonator above a white rectangle, which represents the SQUID device that controls the connections and relationships among the qubits and resonator elements.
This photo shows the central working region of the device. In the lower section, the three large rectangles (light blue) represent the two quantum bits, or qubits, at right and left and the resonator in the center. In the upper, magnified section, driving microwaves through the antenna (large dark-blue rectangle at bottom) induces a magnetic field in the SQUID loop (smaller white square at center, whose sides are about 20 micrometers long). The magnetic field activates the toggle switch. The microwaves’ frequency and magnitude determine the switch’s position and strength of connection among the qubits and resonator.

Webb makes First Detection of Crucial Carbon Molecule

These Webb images show a part of the Orion Nebula known as the Orion Bar. The largest image, on the left, is from Webb’s NIRCam (Near-Infrared Camera) instrument. At upper right, the telescope is focused on a smaller area using Webb’s MIRI (Mid-Infrared Instrument). At the very center of the MIRI area is a young star system with a protoplanetary disk named d203-506. The pullout at the bottom right displays a combined NIRCam and MIRI image of this young system.

Researchers find a New Class of Biomarkers to Predict Treatment Outcomes in Cancer Patients

Researchers find a new of biomarkers to predict treatment outcomes in cancer patients
Cancer is the result of the uncontrolled division and spread of cells into surrounding tissue. Recently researchers have begun to focus on biomarkers as a source of information about different cancers, how they work in the body, and how they can be fought.

One of the big reasons that cancer is difficult to treat is that patients respond to treatments differently, and these differences can rarely be anticipated. In most cases, determining whether and how a patient will respond to any given therapy requires administering it to the patient and then waiting and watching. That is a lot of pressure for researchers and physicians and a lot of risk for cancer patients, and added expense.

If a patient’s response were predictable, optimal thera...

New Type of Computer Memory could greatly Reduce Energy use and Improve Performance

New type of computer memory could greatly reduce energy use and improve performance
Cross-sectional TEM images and energy-dispersive x-ray measurements from high-angle annular dark-field scanning TEM for different thin films. (A) Pure HfOx deposited at 400°C. Clear crystallites are visible in the film; red arrows indicate some of the grain boundaries. (B) Pure HfOx deposited at 30°C. While these films are not polycrystalline like pure HfOx deposited at 400°C, neither are they as uniform as the composite films presented in (C). (C) The thin films which resulted in stable electrical performance are amorphous or nanocrystalline. Some pillar-like structures can be discerned, indicated by red arrows. The addition of Ba to the films clearly leads to material uniformity by suppressing crystallization...
