Shrinking bulky, room-sized, trapped-ion quantum computer hardware to a single, deck of cards- sized photonic chip

"replaces massive, ultrastable lasers/ vibration-isolated vacuum chambers with compact photonic chips controlling qubits directly... far more robust to vibrations, while still needing temperature-control... also applicable to optical clocks: portable, so precise can map Earth's gravitational field to cm level/ enhance deep- navigation... integrating lasers/ ion traps onto a single chip, this research provides the necessary blueprint for mass-producible/ scalable (eventually millions of qubits) quantum hardware"
