A recent study, published in Nature Photonics, by Prof. Yaron Bromberg and Dr. Ohad Lib from the Racah Institute of Physics at the Hebrew University of Jerusalem has made significant strides in advancing quantum computing through their research on photonic-measurement-based quantum computation.
This method holds the potential to overcome some of the challenging obstacles in quantum computation, offering a more scalable and resource-efficient solution by using high-dimensional spatial encoding to generate large cluster states.
Quantum computers are facing a major roadblock in producing large cluster states necessary for computations. The standard approach sees detection probabilities decreasing exponentially as the number of photons increases.
Prof. Bromberg and Dr. Lib's study addresses this issue by encoding multiple qubits within each photon through spatial encoding. This innovative approach has successfully generated cluster states with over nine qubits at a frequency of 100 Hz, a remarkable achievement in the field.
