Verifiable Blind Quantum Computing with Trapped Ions and Single Photons.

We report the first hybrid matter-photon implementation of verifiable blind quantum computing. We use a trapped-ion quantum server and a client-side photonic detection system networked via a fiber-optic quantum link. The availability of memory qubits and deterministic entangling gates enables interactive protocols without postselection-key requirements for any scalable blind server, which previous realizations could not provide.

Multi-client distributed blind quantum computation with the Qline architecture.

Universal blind quantum computing allows users with minimal quantum resources to delegate a quantum computation to a remote quantum server, while keeping intrinsically hidden input, algorithm, and outcome. State-of-art experimental demonstrations of such a protocol have only involved one client. However, an increasing number of multi-party algorithms, e.

Benchmarking of quantum protocols.

Quantum network protocols offer new functionalities such as enhanced security to communication and computational systems. Despite the rapid progress in quantum hardware, it has not yet reached a level of maturity that enables execution of many quantum protocols in practical settings. To develop quantum protocols in real world, it is necessary to examine their performance considering the imperfections in their practical implementation using simulation platforms.

Successful treatment of pulmonary aspergillosis due to in a child affected by systemic lupus erythematosus: A case report from Northeastern Iran.

A6-year-old girl affected to systemic lupus erythematosus with symptoms of fever, weakness, and lethargy, cough, chest pain, and abnormalchest x-ray. The isolated was identified using partial calmodulin gene sequencing. Gradual improvement was observed onday 19 of treatment with amphotericinB (50 mg /day).

Quantum Advantage from Sequential-Transformation Contextuality.

We introduce a notion of contextuality for transformations in sequential contexts, distinct from the Bell-Kochen-Specker and Spekkens notions of contextuality. Within a transformation-based model for quantum computation we show that strong sequential-transformation contextuality is necessary and sufficient for deterministic computation of nonlinear functions if classical components are restricted to mod2 linearity and matching constraints apply to any underlying ontology. For probabilistic computation, sequential-transformation contextuality is necessary and sufficient for advantage in this task and the degree of advantage quantifiably relates to the degree of contextuality.

Continuous-Variable Instantaneous Quantum Computing is Hard to Sample.

Instantaneous quantum computing is a subuniversal quantum complexity class, whose circuits have proven to be hard to simulate classically in the discrete-variable realm. We extend this proof to the continuous-variable (CV) domain by using squeezed states and homodyne detection, and by exploring the properties of postselected circuits. In order to treat postselection in CVs, we consider finitely resolved homodyne detectors, corresponding to a realistic scheme based on discrete probability distributions of the measurement outcomes.

An Exploratory Study of the Experience of Ageing with Ankylosing Spondylitis: 'Same Backdrop but a Changing Scene'.

Objectives: People are living longer with a long-term health condition. Our aim was to develop a greater understanding of the experience and needs of people as they age with ankylosing spondylitis (AS).

Methods: Ethical approval was obtained for six focus groups, with participants over 60 years of age, to explore experiences through peer group discussion.

Demonstration of blind quantum computing.

Quantum computers, besides offering substantial computational speedups, are also expected to preserve the privacy of a computation. We present an experimental demonstration of blind quantum computing in which the input, computation, and output all remain unknown to the computer. We exploit the conceptual framework of measurement-based quantum computation that enables a client to delegate a computation to a quantum server.

Grounded citizens' juries: a tool for health activism?

Involving the public in decision-making has become a bureaucratic pre-occupation for every health agency in the UK. In this paper we offer an innovative approach for local participation in health decision-making through the development of a 'grounded' citizens' jury. We describe the process of one such jury commissioned by a Primary Care Group in the north-west of England, which was located in an area suffering intractable health inequalities.

Uniqueness of the entanglement measure for bipartite pure states and thermodynamics.

We apply the axiomatic approach to thermodynamics presented by Giles to derive a unique measure of entanglement for bipartite pure states. This implies that local manipulations of entanglement in quantum information theory and adiabatic transformations of states in thermodynamics have the same underlying mathematical structure. We discuss possible extensions of our results to mixed and multipartite states.
