NTT and OptQC Target 1 Million Qubits by 2030
November 18, 2025 · 2 min read
NTT Inc. and OptQC Corp. have formalized a collaboration agreement with an ambitious target: developing optical quantum computers capable of operating with one million quantum bits by 2030. The partnership combines NTT's expertise in optical communications with OptQC's specialized knowledge in quantum computing hardware.
OptQC emerges from 25 years of research at the University of Tokyo, positioning itself as a startup focused on room-temperature quantum computing. The company is reportedly advancing toward a processor with 10,000 quantum modes by 2028, supported by $14.3 million in early funding rounds.
NTT brings to the table optical amplification technology that the company claims can generate quantum entanglement 1,000 times faster than conventional s. This innovation could address one of quantum computing's fundamental s: maintaining qubit stability long enough for complex calculations.
Optical quantum computers operate at room temperature and atmospheric pressure, potentially offering significant advantages over competing approaches that require extreme cooling. The technology's lower power consumption makes it particularly attractive for scaling to the million-qubit level envisioned by the partners.
The five-year roadmap outlined in the agreement focuses on developing error-tolerant technologies alongside qubit scaling. Error correction remains a critical hurdle for practical quantum computing, where even minor environmental interference can disrupt calculations.
Beyond technical achievements, the companies position optical quantum computing as a solution to complex global s. Potential applications include accelerating drug , designing novel materials, and improving climate change predictions through more sophisticated modeling.
This collaboration arrives as quantum computing approaches what some analysts call its "utility phase," where machines begin solving problems beyond classical computers' capabilities. The optical approach represents one of several competing pathways in the rapidly evolving quantum landscape.
The partnership between established telecommunications giant NTT and academic spinoff OptQC illustrates how quantum computing development increasingly bridges corporate research and university innovation. Similar collaborations are emerging worldwide as the race for quantum advantage intensifies.
