Toppan, Blueqat Research Team Says New Method Reduces Computation Time on Photonic Quantum Computer

A team of researchers say that a new method reduces computation time and points to the potential of photonic quantum computation.

Toppan and blueqat are reporting in a research paper that they have created a new photonic quantum computation method that significantly reduced computation time.

In a news release, the companies indicate that their method reduces computation time to one twenty-seventh of the time taken using previous methods. They added that this is expected to accelerate photonic quantum computation.

“It’s well known that quantum computers have the potential to contribute to solutions for a range of social issues,” said Takashi Ito, Executive Officer of Toppan’s Digital Innovation Division. “The photonic quantum method is expected to be widely used because room temperature operation is possible and it saves energy, making it a technology that can bring us closer to quantum computers. I hope the results of this research help to drive the practical use of quantum computers using the photonic quantum method.”

The research team relied on tensor networks to simulate quantum computation. The team said that applying singular value decomposition in tensor network structures to continuous-variable (CV) quantum computation helped reduce the computation time.

The company researchers said that future plans include conducting further comparison against other methods and verify. The companies also a plan to create a digital transformation (DX) business that uses photonic quantum methods, something they hope will encourage the use of quantum computers and quantum communication that enable a safe and secure digital society in the future.

“We are starting to see photonic quantum computers being applied for society around the world, and potential for their application is not limited to computation, but is expected to extend to communication and a wide range of other fields,” said Yuichiro Minato, blueqat CEO/CTO. “This research focuses on a technology that can form a bridge between fundamental research and application, and we believe it will advance the practical use of photonic quantum computers significantly.”

The research paper was included in the Posters Program of the International Conference on Quantum Computing and Engineering (QCE), organized by the Institute of Electrical and Electronics Engineers (IEEE). The team included Ryutaro Nagai, blueqat; Takao Tomono, Toppan and Yuichiro Minato, blueqat.
