"Quantum supremacy" revisited: Low-complexity, deterministic solutions of the original Deutsch-Jozsa problem in classical physical systems
Laszlo B. Kish
The original Deutsch-Jozsa (oDJ) problem is for an oracle (realized here as a database) of size N, where, according to their claim, the deterministic solution of the problem on a c…
Does a standalone, "cold" (low-thermal-noise), linear resistor exist without cooling?
Jiaao Song, Laszlo B. Kish
Classical ways of cooling require some of these elements: phase transition, compressor, non-linearity, valve, and/or switch. A recent example is the 2018 patent of Linear Technolog…
Information entropy and thermal entropy: apples and oranges
Laszlo B. Kish, David K. Ferry
The frequent misunderstanding of information entropy is pointed out. It is shown that, contrary to fortuitous situations and common beliefs, there is no general interrelation betwe…
Second Law based definition of passivity/activity of devices
Kyle Sundqvist, David K. Ferry, Laszlo B. Kish
Recently, our efforts to clarify the old question, if a memristor is a passive or active device [1], triggered debates between engineers, who have had advanced definitions of passi…
Waves in a short cable at low frequencies, or just hand-waving?
L. B. Kish, S. P. Chen, C. G. Granqvist +1
We address the question of low-frequency signals in a short cable, which are often considered as waves in engineering calculations. Such an assumption violates several laws of phys…
Zero-point term and quantum effects in the Johnson noise of resistors: A critical appraisal
Laszlo B. Kish, Gunnar A. Niklasson, Claes G. Granqvist
There is a longstanding debate about the zero-point term in the Johnson noise voltage of a resistor. This term originates from a quantum-theoretical treatment of the Fluctuation-Di…
