Cellular automata can simulate many complex physical phenomena using the power of simple rules. The presented methodological platform expresses the concept of programmable matter in which Newtons laws of motion are one of examples. Energy has been introduced as the equivalent of the Game of Life mass, which can be treated as first level of approximation. The temperature presence and propagation was calculated for various lattice topology and boundary conditions by using the Shannon entropy measure. The conducted study provides strong evidence that despite not fulfillment the principle of mass and energy conservation, the entropy, mass distribution and temperatures approaches thermodynamic equilibrium. In addition, the described cellular automata system transits from positive to a negative temperatures that stabilizes and can be treated as a signature of system dynamical equilibrium. Furthermore the system dynamics was presented in case of few species of cellular automata competing for maximum presence on given lattice with different boundary conditions.

We present a generalized electrostatic SWAP gate realized in a chain of two double quantum dots operated in the single-electron regime. Using a minimalist tight-binding model, we derive analytical results and corroborate them with numerical simulations. We exploit the charge anticorrelation arising from Coulomb repulsion and quantify the resulting entanglement generation. We contrast classical and quantum descriptions and show how device geometry and coupling strengths govern entanglement dynamics and gate performance. The results are relevant to cryogenic, CMOS-compatible quantum technologies and suggest a route toward large-scale semiconductor implementations of quantum logic. Finally, we outline a systematic procedure for translating classical electrostatic logic gates into single-electron quantum gates.

Derivation of tight-binding model from Schroedinger formalism for various topologies of position-based semiconductor qubits is presented in this work in case of static and time-dependent electric fields. Simplistic tight-binding model allows for description of single-electron devices at large integration scale. The case of two electrostatically Wannier qubits (that are also known as position based qubits) in Schroedinger model is presented with omission spin degrees of freedom. The concept of programmable quantum matter can be implemented in the chain of coupled semiconductor quantum dots. Indeed highly integrated and developed cryogenic CMOS nanostructures can be mapped to coupled quantum dots, whose connectivity can be controlled by voltage applied across transistor gates as well as external magnetic field. Using anti-correlation principle arising from Coulomb repulsion interaction between electrons one can implement classical and quantum inverter (Classical/Quantum Swap gate) and many other logical gates. This anti-correlation will be weaken due to the fact of quantumness of physical process is bringing coexistence of correlation and anti-correlation at the same time. One of the central results presented in this work relies on the emergence of dissipation processes during smooth bending of semiconductor nanowires both in the case of classical and quantum picture. We observe strong localization of wave-packet due to nanowire bending. The obtained results can be mapped to problem of electron in curved space, so they can be expressed by programmable position-dependent metric embedded in Schroedinger equation. Indeed semiconductor quantum dot system is capable of mimicking the curved space what provides bridge between fundamental and applied science present in implementation of single-electron devices.

This work presents experimental and theoretical comparison in the modelling of the quantum wave function of single-electron in semiconductor nanowire via classical analog electronics based hardware emulator with the use of Kron concept. Thus we are able to express the semiconductor single-electron devices of linear or closed circle topology as present in position-based qubits that can be mapped essentially to one dimensional Kron model implemented experimentally. We have also represented a two dimensional single-electron wave function in Krons model and point out future experiments to be conducted.
