Researchers generate high-quality quantum light with modular waveguide device opticalsociety OpticalSociety
"Our goal is to dramatically improve information processing by developing faster quantum computers that can perform any type of computation without errors," said research team member Kan Takase from the University of Tokyo."Although there are several ways to create a quantum computer, light-based approaches are promising because the information processor can operate at room temperature and the computing scale can be easily expanded.
"We want to increase the clock frequency of optical quantum computers, which can, in principle, achieve terahertz frequencies," said Takase."Higher clock frequencies enable faster execution of computational tasks and allow the delay lines in the optical circuits to be shortened. This makes optical quantum computers more compact while also making it easier to develop and stabilize the overall system.
OPAs use nonlinear optical crystals to generate squeezed light, but conventional OPAs don't generate the quantum light with the properties necessary for faster quantum computing. To overcome this challenge, researchers from the University of Tokyo and NTT Corporation developed an OPA based on a waveguide-type device that achieves high efficiency by confining light to a narrow crystal.

Researchers generate the first complete, gapless sequence of a human genome -- ScienceDailyScientists have published the first complete, gapless sequence of a human genome, two decades after the Human Genome Project produced the first draft human genome sequence. According to researchers, having a complete, gap-free sequence of the roughly 3 billion bases (or 'letters') in our DNA is critical for understanding the full spectrum of human genomic variation and for understanding the genetic contributions to certain diseases.
