Researchers at the University of Twente’s MESA+ Research Institute have transmitted more than 10 bits of information using a single photon. They achieved this using an ingenious method for detecting individual photons. They say that the knowledge gained from this study can be used to improve the security and speed of quantum communication.

The research results were published in the scientific journal Optics Express.

When asked “How much information can you transmit using just a single photon?” most scientists would answer ‘one bit’ (either a ‘1’ or a ‘0’). In theory, however, there is no limit to the amount of information you can transmit with a single photon...
