Summary
Quantum computation holds promise for enormous advancements in human's computational power. Among various possible approaches, quantum computation in the optical continuous-variable (CV) platform offers room-temperature compatibility and unprecedented potential for scalability into millions of entangled modes. However, the platform needs to demonstrate its power in practical applications and in encoding qubits that are compatible with fault-tolerant computational architectures.
Here, I propose the GTGBS project, which paves the way for addressing these challenges by realising the Gaussian boson sampling (GBS) protocol to leverage the computational power of the platform. The major improvement of the GTGBS project is that it will use the gate teleportation technique in CV quantum optics to replace the large interferometer array in the current realisations of GBS with a simple measurement–feed-forward structure. The GTGBS project is expected to overcome the effect of photon losses in the interferometer that has a significant detrimental effect on the scalability of GBS experiments. Meanwhile, it has excellent compatibility with the measurement-based quantum computation architecture, a promising technical route to realise fault-tolerant quantum computation in the CV optical platform.
The GTGBS project has a high potential impact: by improving the performance of the GBS experiments, the developed setup will acquire the computational power to solve practical, interdisciplinary problems like combinatorial optimisation and drug design. Furthermore, the setup can serve as a resource state preparator for fault-tolerant CV quantum computation. It is thus plausible that the GTGBS project will make a solid contribution to the development of quantum technology and provide several practical applications in industry.
