NTT, Inc. and OptQC Corp. have signed a collaboration agreement aimed at realizing scalable and highly reliable optical quantum computers, with a goal of achieving one million quantum bits (qubits) and establishing error-tolerant technologies by 2030. The partnership will leverage NTT’s advanced optical communication and error correction technologies with OptQC’s expertise in optical quantum computer development.

OptQC, a startup based on 25 years of optical quantum computing research at the University of Tokyo, is developing a highly scalable, room-temperature optical quantum computer. The company is currently advancing a large-scale processor targeting 10,000 quantum modes by 2028 and has raised $14.3 million in early funding rounds. NTT will contribute its innovations, such as optical amplification technology that previously achieved quantum entanglement generation 1,000× faster than conventional methods.

The joint study outlines a five-year roadmap with the following primary areas of collaboration:

  • Development of multiplexing and error correction technologies applicable to optical quantum computers.
  • Creation of use cases and development of algorithms and software.
  • Building a supply chain for optical quantum computers.

Optical quantum computers, which operate at room temperature and atmospheric pressure with low power consumption, are positioned by the companies as a promising approach for addressing complex social challenges like drug discovery, new material design, and climate change prediction.
