Developed by researchers at the University of Bristol’s Quantum Engineering Technology Labs and Bristol Robotics Laboratory (BRL), the invention boasts a distinctive design that enables the execution of quantum experiments with unparalleled levels of speed, precision, and intricacy. Quantum technology holds vast potential for real-world applications, ranging from advancements in cellular monitoring for health purposes to interstellar communication.

Quantum experiments often demand highly controlled environments, involving factors such as ultra-low temperatures, atomic-scale interactions, and precisely aligned laser beams. The integration of robotic features into these experiments empowers scientists to explore them with heightened prototyping speed, control, and resilience.

The research findings, along with the groundbreaking robotic arm, were detailed in the journal Advanced Science on November 17th, 2023.

We couldn’t have performed this experiment using standard lab components, so we decided to look into robotics. We’ve shown that robotic arms are mature enough to navigate very complex settings. We’re very keen for this technology to improve all sorts of quantum sensing experiments, and hopefully leading to these experiments leaving the quantum optics lab and find further useful applications, like in cell diagnostics.
