Yet-to-be discovered axions and axion-like particles may be the key to explaining some of the deepest puzzles of our universe, such as dark matter and charge-parity violation in strong interactions. Several recent theories have predicted that the masses of axions probably lie within the well-motivated "axion window" (0.01 meV–1 meV). However, existing laboratory searches and astrophysical observation mostly search for the axions outside the axion window.

18:03 Phys.org New method of controlling qubits could advance quantum computers (2)

Quantum computing, a field that relies on the principles of quantum mechanics to calculate outcomes, has the potential to perform tasks too complex for traditional computers and to do so at high speeds, making it in some ways the new frontier for science and engineering. To get to the point where quantum computers can meet their expected performance potential, the development of large-scale quantum processors and quantum memories is needed. Precise control of qubits—or quantum bits, the basic building blocks of quantum computers—is critical to do this, but methods of controlling qubits have limitations for massive high-density wiring with high precision.
