The Universe as Quantum Computer

Seth Lloyd

This article reviews the history of digital computation, and investigates just how far the concept of computation can be taken.In particular, I address the question of whether the universe itself is in fact a giant computer, and if so, just what kind of computer it is.I will show that the universe can be regarded as a giant quantum computer.The quantum computational model of the universe explains a variety of observed phenomena not encompassed by the ordinary laws of physics.In particular, the model shows that the the quantum computational universe automatically gives rise to a mix of randomness and order, and to both simple and complex systems.

Interfacing External Quantum Devices to a Universal Quantum Computer

Antonio A. Lagana, Max A. Lohe, Lorenz von Smekal

We present a scheme to use external quantum devices using the universal quantum computer previously constructed. We thereby show how the universal quantum computer can utilize networked quantum information resources to carry out local computations. Such information may come from specialized quantum devices or even from remote universal quantum computers. We show how to accomplish this by devising universal quantum computer programs that implement well known oracle based quantum algorithms, namely the Deutsch, Deutsch-Jozsa, and the Grover algorithms using external black-box quantum oracle devices. In the process, we demonstrate a method to map existing quantum algorithms onto the universal quantum computer.

Catalytic Transformation from Computationally Universal to Strictly Universal Measurement-Based Quantum Computation

Yuki Takeuchi

There are two types of universality in measurement-based quantum computation (MBQC): strict and computational. It is well known that the former is stronger than the latter. We present a method of transforming from a certain type of computationally universal MBQC to a strictly universal one. Our method simply replaces a single qubit in a resource state with a Pauli-Y eigenstate. We applied our method to show that hypergraph states can be made strictly universal with only Pauli measurements, while only computationally universal hypergraph states were known.
