Using laser light, researchers have innovated a precise method to control individual barium qubits, advancing prospects for quantum computing.The 3 Most Secretive Zodiac Signs #astrology #zodiacResearchers have pioneered a groundbreaking technique utilizing laser light to control individual qubits made of barium more robustly than any other method currently known. Reliably controlling qubits is a critical step towards actualizing functional quantum computers of the future.
“This means we can talk to any ion without affecting its neighbors while also retaining the capability to control each individual ion to the maximum possible extent. This is the most flexible ion qubit control system with this high precision that we know of anywhere, in both academia and industry.” Green laser light is the correct energy to manipulate the energy states of barium ions. Credit: University of WaterlooBarium ions were targeted by the scientists, as they are becoming increasingly popular in the field of trapped ion quantum computation. Barium ions have convenient energy states that can be used as the zero and one levels of a qubit and be manipulated with visible green light, unlike the higher energy ultraviolet light needed for othertypes for the same manipulation.
“This work is part of our effort at the University of Waterloo to build barium ion quantum processors using atomic systems,” said Dr. Crystal Senko, Islam’s co-principal investigator and a faculty member at IQC and Waterloo’s Department of Physics and Astronomy. “We use ions because they are identical, nature-made qubits, so we don’t need to fabricate them. Our task is to find ways to control them.
The innovative waveguide method demonstrates a simple and precise method of control, showing promise for manipulating ions to encode and process quantum data and for implementation in quantum simulation and computing.level intensity crosstalk” by Ali Binai-Motlagh, Matthew L Day, Nikolay Videnov, Noah Greenberg, Crystal Senko and Rajibul Islam, 27 July 2023,
