A recent study published in Nature Photonics by Professor Yaron Blomberg and Dr. Ohad Rib of the Raka Institute of Physics at the Hebrew University of Jerusalem takes a major step forward in the advancement of quantum computing through the study of optical measurement-based quantum computing. .
This method has the potential to overcome some of the difficult obstacles in quantum computing and provides a more scalable and resource-efficient solution by using high-dimensional spatial encoding to generate large cluster states. We provide.
Quantum computers face major obstacles in generating the large cluster states needed for computation. In the standard approach, the detection probability decreases exponentially as the number of photons increases.
Professor Blomberg and Dr. Lib’s research addresses this problem by encoding multiple qubits within each photon through spatial encoding. This innovative approach successfully generated cluster states of more than 9 qubits at a frequency of 100 Hz. This is a remarkable achievement in this field.
Additionally, the researchers demonstrated that this method significantly reduces computational time by allowing instantaneous feedforward between qubits encoded within the same photon. This breakthrough opens the door to more resource-efficient quantum computing and could lead to faster, fault-tolerant quantum computers that can handle complex problems.
Professor Blomberg said: “Our results show that the use of high-dimensional encoding not only overcomes previous scalability barriers, but also provides a practical and efficient approach to quantum computing. “This shows great progress.”
Dr. Lib added, “By addressing both the scalability and computational time issues, we have opened a new path in measurement-based quantum computing. The future of quantum technology is a little closer.”
This research marks an important milestone in the continued quest to realize the full potential of quantum computing through photonics.
