controllable

Researchers are claiming a breakthrough in quantum communications, thanks to a new diamond-stretching technique they say greatly increases the temperatures at which qubits remain entangled, while also making them microwave-controllable. Quantum networking is an emerging field that uses weird quantum phenomena to send and receive information. These networks will be impossible to hack, and will use quantum entanglement to cover large distances, creating pairs of qubits which mirror each other's quantum state without any…

Chiral Quasi Bound States in the Continuum for High-Purity Circularly Polarized Light SourceScientists demonstrate high-purity, highly directional, and high-Q circularly polarized light source from spontaneous emission to laser.An ultra-compact circularly polarized light source is a crucial component for the applications of classical and quantum optics information processing. The development of this field relies on the advances of two technologies, quantum materials and chiral optical cavities.Disadvantages of…

The study found that each of the risk factors led to a decrease in cognitive performance of up to three years.A new study finds that dementia risk might be more determined by lifestyle rather than age.According to recent Baycrest research, adults without dementia risk factors like smoking, diabetes, or hearing loss had brain health comparable to that of those who are 10 to 20 years younger than them. According to the research, only one dementia risk factor can age a person’s cognition by up to three years.“Our results…
