| 520 | _ | _ | |a In Quantum computing, ensuring the stability of qubits is crucial due to their extreme temperature sensitivity. To achieve this, qubits are kept at millikelvin temperatures to minimize thermal disruptions, while high frequency microwave signals with broad data bandwidth are necessary to drive them effectively. Currently, the prevalent approach involves using robust coaxial cables to transmit signals between room temperature electronics and the cryogenic environment where qubits reside. However, as quantum computers scale up with more qubits, coaxial cables face limitations due to cabling bottlenecks and thermal issues, prompting exploration of photonic links as a promising alternative. RF photonics has shown advanced capabilities at room temperature, offering high signal quality, low noise, and significant bandwidth compared to coaxial cables. Therefore, investigating the performance of RF photonics in cryogenic conditions becomes imperative. This study presents findings on the performance of a photonic link utilizing laser photodiodes, demonstrating the behavior of Silicon and InGaAs photodiodes when subjected to high frequency signals in a cryogenic environment. Importantly, this photonic link has the capability to directly drive both qubits and electronics in the 4K stage passively without any biasing. |
