A computer in which all internal circuits use light instead of electricity. Long predicted, an all-optical computer is not expected for some time as there are hurdles to overcome. However, there are ...

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 ...

We always hear that future computers will use optical technology. But what will that look like for a general-purpose computer? German researchers explain it in a recent scientific paper. Although the ...
