Quantum computing: Laser-optical system offers full control over 2,000 trapped Rydberg atoms
Fraunhofer ILT in Aachen has developed a highly complex laser-optical system for a quantum computer currently under construction at the 5th Institute of Physics at the University of Stuttgart. This system enables 2,000 Rydberg atoms to be positioned with submicrometer precision in the computer's highly compact vacuum chamber. To do this, the system projects an array of 2,000 individually controllable laser beams into the chamber. These beams act as optical tweezers and hold the trapped Rydberg atoms precisely at the distance required for them to interact with each other. The computer's quantum
Advances in laser-optical systems are converging with quantum computing research, enabling more precise control over larger numbers of qubits within experimental setups.
This development represents a significant step towards scalable quantum computing by demonstrating precise control over 2,000 Rydberg atoms, a key challenge in building powerful quantum computers.
The ability to accurately position and manipulate 2,000 individual Rydberg atoms through optical tweezers significantly pushes the boundaries for qubit density and interaction capabilities in quantum hardware.
