Multi-Wavelength Reconfigurable Optical Control Apparatus for Large-Scale Quantum Systems

Resumen de: US20260259404A1

Many quantum systems, including arrays of trapped atoms, trapped ions, and color centers in solid-state hosts, are controlled with optical control signals. As quantum systems increase in size to thousands of channels or more, however, it can be challenging to generate enough optical control signals to control them. A multi-wavelength reconfigurable optical control apparatus uses lasers, high-speed modulators, a reconfigurable spatial light modulator (SLMs), and a fast beam scanner to address thousands of qubits. The lasers generate beams at the qubits' resonant wavelengths; the modulators modulate the beams with control pulses at gigahertz rates; the SLM re-projects the beams into a geometry matched to the quantum operation and the geometry of the qubit array; and the beam scanner scans the beams across the qubit array at kilohertz to megahertz rate. This enables the control apparatus to address CN the entire array before the qubits' coherence time has elapsed.
