We demonstrate a tunable narrowband filter based on optical-pumping-induced circular dichroism in rubidium vapor. The filter achieves a peak transmission of 14.6%, a linewidth of 80 MHz, and an out-of-band extinction of >or=35 dB. The transmission peak can be tuned within the range of the Doppler linewidth of the D1 line of atomic rubidium at 795 nm. While(More)

Randomness plays a fundamental role in the security of cryptographic protocols, as well as in the accuracy of numerical simulations. A system that violates a Bell inequality with a closed detection loophole and clear separation between its subsystems can be used to generate random numbers that are certified, i.e. both secure and truly random [1]. Given the(More)
