Abstract
A random signal can be obtained from a random tunnelling of charges from one conductor to another conductor across a quantum tunnelling barrier. The random signal can be amplified and associated to a random number. The association can be performed repetitively to generate a sequence of random numbers.
Claims12
A random number generator comprising:
- a quantum tunnelling barrier having an insulator having two exterior opposite faces each in contact with a corresponding one of two conductors and allowing charges to randomly tunnel from one of the conductors to the other conductor across the insulator to form a current of tunneled charges passing through the insulator, the current of tunneled charges having an instantaneous level varying randomly due to quantum tunneling and forming a random signal, wherein each one of the conductors is configured to be connectable to a corresponding terminal of a voltage source;
- an amplifier connected to one of the two conductors for amplifying the random signal;
- and
- a sampling device connected to the amplifier for associating, in real time, the instantaneous level of the amplified random signal to at least one random number.
