Quantum computation by communication
We present here a new approach to scalable quantum computing—a ‘qubus computer’—which realizes qubit measurement and quantum gates through interacting qubits with a quantum communication bus mode. The qubits could be ‘static’ matter qubits or ‘flying’ optical qubits, but the scheme we focus on here is particularly suited to matter qubits. There is no requirement for direct interaction between t...
متن کاملBook review on quantum computation and quantum information
In a space of less than ten years, a cadre of inspired researchers from theoretical and experimental physics, computer science, and mathematics have been incessantly at work building an entirely new body of knowledge about the information processing capabilities of quantum systems. The amount of wisdom accumulated in these short years already presses at the limits of what one mind can reasonabl...
متن کاملCommunication capacity of quantum computation.
By considering quantum computation as a communication process, we relate its efficiency to its classical communication capacity. This formalism allows us to derive lower bounds on the complexity of search algorithms in the most general context. It enables us to link the mixedness of a quantum computer to its efficiency and also allows us to derive the critical level of mixedness beyond which th...
متن کاملA review of quantum thermodynamics
In this article, we present a brief and elementary review of quantum thermodynamics and its achievements and challenges. This review includes an introduction to some fundamental concepts such as internal energy, heat, work, entropy, entropy production, thermal equilibrium, second law of quantum thermodynamics, relation between thermodynamics and information theory, as well as a discussion of ho...
متن کاملNovel Systems and Methods for Quantum Communication, Quantum Computation, and Quantum Simulation
Precise control over quantum systems can enable the realization of fascinating applications such as powerful computers, secure communication devices, and simulators that can elucidate the physics of complex condensed matter systems. However, the fragility of quantum effects makes it very difficult to harness the power of quantum mechanics. In this thesis, we present novel systems and tools for ...
