Scientists in the United States have developed a new type of “optical cavity” that ...

Japanese researchers have helped develop an optical quantum computer that has the potential to drastically reduce the size of the next-generation computer and do even faster calculations. Because a ...

A light has emerged at the end of the tunnel in the long pursuit of developing quantum computers, which are expected to ...

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian ...

We have developed a system for publishing the optical quantum computer developed by the R&D theme 4 on the cloud, as shown in Figure 1. Fig.1 Optical quantum computer cloud system When making the ...

Using the time-domain multiplexing techniques developed by the R&D theme 1, we have generated large-scale cluster states that are currently unachievable by other methods. In particular, the generated ...

NTT and OptQC aim to build a 1-million qubit quantum computer based on light, rather than electricity, to enhance reliability, scalability and practicality. Use cases for a practical optical quantum ...

Optical quantum computers are gaining attention as a next-generation computing technology with high speed and scalability. However, accurately characterizing complex optical processes, where multiple ...
