Algorithmic approach to quantum physics
Yuri Ozhigov
Algorithmic approach is based on the assumption that any quantum evolution of many particle system can be simulated on a classical computer with the polynomial time and memory cost…
Limitation of computational resource as physical principle
Yuri I. Ozhigov
Limitation of computational resources is considered as a universal principle that for simulation is as fundamental as physical laws are. It claims that all experimentally verifiabl…
Easy Control over Fermionic Computations
Yuri Ozhigov
Quantum fermionic computations on occupation numbers proposed in quant-ph/0003137 are studied. It is shown that a control over external field and tunneling would suffice to fulfill…
Quantum Computer with Fixed Interaction is Universal
Yuri Ozhigov, Leonid Fedichkin
It is proved that a quantum computer with fixed and permanent interaction of diagonal type between qubits proposed in the work quant-ph/0201132 is universal. Such computer is contr…
Implementation of Quantum Fourier Transform and Simulation of Wave Functions by Fixed Interaction
Yuri Ozhigov
We study a quantum computer with fixed and permanent interaction of diagonal type between qubits. It is controlled only by one-qubit quick transformations. It is shown how to imple…
Quantum recognition of eigenvalues, structure of devices and thermodynamic properties
Yuri I. Ozhigov
Quantum algorithms speeding up classical counterparts are proposed for the problems: 1. Recognition of eigenvalues with fixed precision. Given a quantum circuit generating unitary…
