QuEra Computing, a quantum technology startup, secured $230 million in a significant investment round involving key players like Google and SoftBank. Focused on neutral atom-based quantum computers, QuEra utilizes lasers to stabilize and manipulate individual atoms, potentially extending coherence times beyond one second. Established in 2018 and having collaborated with institutions like Harvard and MIT, QuEra operates the largest publicly accessible quantum computer. With the recent funding, QuEra aims to develop fault-tolerant quantum technology and plans to expand its workforce and testing capacities to improve scalability.
We use lasers, acting as optical tweezers, to trap individual atoms in place. The lasers suppress atomic movement, effectively cooling the atoms down to nearly absolute zero temperature.
At these temperatures, the individual discrete energy levels of the atoms can be resolved and manipulated, some of them leading to huge coherence times exceeding one second.
