In a monumental leap for the world of technology, a pioneering quantum computing chip has shattered performance barriers, paving the way for an era of computing power previously thought to be science fiction. Developed by a collaboration of leading tech companies and research institutions, this quantum computing breakthrough is set to redefine the landscape of computing, enabling unprecedented speeds and capabilities that could revolutionize industries across the board. Key Highlights of the Quantum Computing Breakthrough: Unprecedented Processing Power: Traditional computers use bits to process information, represented as 0s and 1s. Quantum computers, on the other hand, leverage quantum bits or qubits, which can exist in a superposition of both 0 and 1 states simultaneously. This inherent parallelism allows quantum computers to perform complex calculations at speeds that would be inconceivable for classical computers. Massive Quantum Supremacy: The newly developed quantum chip achie
A team of researchers at the University of Cambridge has developed a brain training app that can improve concentration against daily distractions that people face in a connected world. The team demonstrated that playing the game app called 'Decoder' on an iPad for eight hours over one month improved attention and concentration. This form of attention activates a frontal-parietal network in the brain, said the researchers from the Behavioural and Clinical Neuroscience Institute at the University of Cambridge.
"We've all experienced coming home from work feeling that we've been busy all day, but unsure what we actually did," said Professor Barbara Sahakian from the Department of Psychiatry. For complex tasks, we need to get in the "flow" and stay focused, she added in the study published in the journal Frontiers in Behavioural Neuroscience. To reach this conclusion, the researchers divided 75 healthy young adults into three groups: one group received "Decoder", one control group played Bingo for the same amount of time and a second control group received no game.
All 75 participants were tested at the start of the trial and then after four weeks. The results showed that those who played "Decoder" were better than those who played Bingo and those who played no game.
"The difference in performance was significant and meaningful as it was comparable to those effects seen using stimulants, such as methylphenidate, or nicotine," said the team. To ensure that "Decoder" improved focused attention and concentration without impairing the ability to shift attention, the researchers also tested participants' ability on the "Trail Making Test".
"Decoder" performance also improved on this commonly used neuropsychological test of attentional shifting.
"In addition to healthy people, we hope that the game will be beneficial for patients who have impairments in attention, including those with ADHD or traumatic brain injury. We plan to start a study with traumatic brain injury patients this year," said Professor Sahakian. The game has now been licensed to app developer Peak.
Peak on Monday released the game, as part of the Peak Brain Training app, on Apple App Store for free. The Android version would come later this year.
