An absolutely secure, fast, inexpensive, robust, maintenance-free and low-power-consumption communication is proposed. The states of the information bit are represented by two resistance values. Theâ€¦ (More)

The exponential growth of memory size and clock frequency in computers has a great impact on everyday life. The growth is empirically described by Mooreâ€™s law of miniaturization. Physical limitationsâ€¦ (More)

A pair of Kirchhoff-loopâ€“Johnson(-like)â€“Noise communicators, which is able to work over variable ranges, was designed and built. Tests have been carried out on a model-line performanceâ€¦ (More)

We introduce a purely electrical version of Maxwell's demon which does not involve mechanically moving parts such as trapdoors, etc. It consists of a capacitor, resistors, amplifiers, logic circuitryâ€¦ (More)

We critically analyze the results and claims in [Physics Letters A 373 (2009) 901â€“904]. We show that the strong security leak appeared in the simulations is only an artifact and not caused byâ€¦ (More)

There is a longstanding debate about the zero-point term in the Johnson noise voltage of a resistor. This term originates from a quantumtheoretical treatment of the fluctuation-dissipation theoremâ€¦ (More)

a r t i c l e i n f o a b s t r a c t about noise-based logic, we showed how simple superpositions of single logic basis vectors can be achieved in a single wire. The superposition components wereâ€¦ (More)

We introduce seven new versions of the Kirchhoff-Law-Johnson-(like)-Noise (KLJN) classical physical secure key exchange scheme. While these practical improvements offer progressively enhancedâ€¦ (More)

We refute a physical model, recently proposed by Gunn, Allison and Abbott (GAA) [http://arxiv.org/pdf/1402.2709v2.pdf], to utilize electromagnetic waves for eavesdropping on theâ€¦ (More)

This talk addressed the following questions in the public debate at HoTPI: (i) energy dissipation limits of switches, memories and control; (ii) whether reversible computers are possible, or doesâ€¦ (More)
