A circular-sided square microcavity laser etched a central hole has achieved chaos
operation with a bandwidth of 20.8 GHz without external optical feedback or injection, in …

To achieve complete security of communication, there is a need for “real-time” ultrafast
physical random bit generators (RBGs). In the available physical RBGs, random bit …

We describe a methodology and standard of proof for experimental claims of quantum
random-number generation (QRNG), analogous to well-established methods from precision …
