Researchers Aim to Make Quantum Computers More Independent with Autonomous Gates
Researchers are working on making quantum computers more independent, reducing the need for precise external control. They're exploring ways to create entangling gates with high quantum autonomy using various platforms.
The team investigated three platforms: Rydberg atoms, trapped ions, and superconducting circuits. For trapped ions, sculpting linear Paul traps or ring traps can perform Z or entangling gates with minimal external control, driven by the ion's motion within the trap. Dr. Alexander Glätzle and collaborators at planqc have published proposals for implementing these gates, with projects funded to complete by 2026 and 2027 in Germany and Austria.
For Rydberg atoms, the Levine-Pichler gate can be driven by phase-locked PMLLs for autonomous operation. Calculations show PMLLs can emit pulses with the required wavelengths and durations to drive the Rydberg transition. Methods like Rydberg-blockade interactions or ultrafast transitions can also create entangling gates on Rydberg atoms with minimal external control. A team led by José Antonio María Guzman and Yu-Xin Wang has proposed a pathway towards achieving this goal.
These quantum-autonomous gates can serve as fundamental building blocks for constructing more complex, fully or partially autonomous quantum circuits, reducing the burden of classical control. Future work includes experimentally implementing these gate proposals and exploring universal gate sets achievable through chaining these autonomous gates.
