Analysis of heterostructures for spintronics shows how two desired quantum-physical effects reinforce each other
Spintronics uses the spins of electrons to perform logic operations or store information. Ideally, spintronic devices could operate faster and more energy-efficiently than conventional semiconductor devices. However, it is still difficult to create a.....»»
Could interstellar quantum communications involve Earth or solve the Fermi paradox?
Thus far, the search for extraterrestrial intelligence (SETI) has used strategies based on classical science—listening for radio waves, telescopes watching for optical signals, telescopes in orbit scouring light from the atmospheres of exoplanets,.....»»
Were Bohr and von Neumann really in conflict over quantum measurements?
Analysis suggests that the two pioneers of quantum mechanics, Niels Bohr and John von Neumann, may have had more similar views than previously thought regarding the nature of quantum systems, and the classical apparatus used to measure them......»»
Data disposal and cyber hygiene: Building a culture of security within your organization
Data breach episodes have been constantly rising with the number of data breach victims crossing 1 billion in the first half of 2024. A recent Data Breach Report 2023 by Verizon confirms that 74% of data breaches are due to human errors. Although cyb.....»»
LHC experiments observe quantum entanglement at the highest energy yet
Quantum entanglement is a fascinating feature of quantum physics—the theory of the very small. If two particles are quantum-entangled, the state of one particle is tied to that of the other, no matter how far apart the particles are. This mind-bend.....»»
