Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory may have found a way to resolve this dilemma. It involves a scintillator material composed of spherical particles that are 20 billionths of a meter in size. Even though they are incredibly small, these nanoparticles have an intricate structure composed of a ball-like core of cadmium sulfide surrounded by a thin shell of cadmium selenide and a thicker shell of cadmium sulfide. Collaborating on this project were scientists from DOE’s Oak Ridge National Laboratory, Bowling Green State University (BGSU) and Northwestern University.

Purdue University researchers have developed patent-pending one-dimensional boron nitride nanotubes (BNNTs) containing spin qubits, or spin defects. The BNNTs are more sensitive in detecting off-axis magnetic fields at high resolution than traditional diamond tips used in scanning probe magnetic-field microscopes.

Canada and France have a strong history of cooperation in science, technology and innovation. To this end, the Natural Sciences and Engineering Research Council of Canada (NSERC) is pleased to announce its support of eight collaborative research projects focused on quantum computing hardware and software. NSERC’s investment in these projects is close to CAN $2.2 million over three years.

In the CiRQus project, we have implemented laser-controlled interactions between a highly-excited circular Rydberg qubit and a second ionic core electron. This achievement advances control of circular Rydberg atoms from the microwave to the optical domain by combining established tools for manipulating trapped ions with neutral atom arrays.

Prof. Michał Parniak and Michał Lipka from the University of Warsaw (UW) is Faculty of Physics developed a quantum-inspired super-resolving spectrometer for short pulses of light. In the future the device can be miniaturized on a photonic chip and applied in optical and quantum networks as well as in spectroscopic studies of matter. The invention was presented by the researchers in “Optica”.

A research team led by Professor Monika Aidelsburger and Professor Immanuel Bloch from the LMU Faculty of Physics has investigated this question concerning quantum many-body systems and found indications that they can be described macroscopically through simple diffusion equations with random noise. The study was recently published in the journal Nature Physics.

Although systems consisting of many interacting small particles can be highly complex and chaotic, some can nonetheless be described using simple theories. Does this also pertain to the world of quantum physics? A research team led by Professor Monika Aidelsburger and Professor Immanuel Bloch from the LMU Faculty of Physics investigated this question concerning quantum many-body systems and found indications that they can be described macroscopically through simple diffusion equations with random noise. The study was recently published in the journal Nature Physics.

Researchers from the California NanoSystems Institute at UCLA and their colleagues have received a one-year, $1 million grant as part of a new National Science Foundation program aimed at accelerating the development and commercialization of quantum technologies for the benefit of society.

Cornell University researchers have demonstrated that acoustic sound waves can be used to control the motion of an electron as it orbits a lattice defect in a diamond, a technique that can potentially improve the sensitivity of quantum sensors and be used in other quantum devices.

Dynamic nuclear polarization (DNP) has revolutionized the field of nanoscale nuclear magnetic resonance (NMR), making it possible to study a wider range of materials, biomolecules and complex dynamic processes such as how proteins fold and change shape inside a cell.
