Intrinsic quantum computation

Intrinsic Quantum Computation

We introduce ways to measure information storage in quantum systems, using a recently introduced computation-theoretic model that accounts for measurement effects. The first, the quantum excess entropy, quantifies the shared information between a quantum process’s past and its future. The second, the quantum transient information, determines the difficulty with which an observer comes to know t...

Quantum Dot Quantum Computation

Within the last few years, quantum computation has developed into a truly interdisciplinary field involving the contributions of physicists, engineers, and computer scientists. There have been several experimental studies in order to find the proper physical realization of qubits to perform quantum computation. One of the most promising candidates for qubits is the spin state of the electrons, ...

Quantum Computation via Paraconsistent Computation

We present an original model of paraconsistent Turing machines (PTMs), a generalization of the classical Turing machines model of computation using a paraconsistent logic. Next, we briefly describe the standard models of quantum computation: quantum Turing machines and quantum circuits, and revise quantum algorithms to solve the so-called Deutsch’s problem and Deutsch-Jozsa problem. Then, we sh...

In the last few years, theoretical study of quantum systems serving as computational devices has achieved tremendous progress. We now have strong theoretical evidence that quantum computers, if built, might be used as a dramatically powerful computational tool, capable of performing tasks which seem intractable for classical computers. This review is about to tell the story of theoretical quant...
