Synthesis of Quantum Circuits for Linear Nearest Neighbor Architectures
While a couple of impressive quantum technologies have been proposed, they
have several intrinsic limitations which must be considered by circuit
designers to produce realizable circuits. Limited interaction distance between
gate qubits is one of the most common limitations. In this paper, we suggest
extensions of the existing synthesis flow aimed to realize circuits for quantum
architectures with linear nearest neighbor (LNN) interaction. To this end, a
template matching optimization, an exact synthesis approach, and two reordering
strategies are introduced. The proposed methods are combined as an integrated
synthesis flow. Experiments show that by using the suggested flow, quantum cost
can be improved by more than 50% on average.Comment: 14 pages, 11 figures, 3 table
Information and Control in Gray-Box Systems
In modern systems, developers are often unable to modify the underlying operating system. To build services in such an environment, we advocate the use of gray-box techniques. When treatin
Massive prolactinoma with galactorrhoea in a prepubertal boy.
An 8 year old prepubertal boy presented with raised intracranial pressure, left proptosis and was noted to have galactorrhoea. Cranial computerized tomography revealed a large pituitary tumour infiltrating the cavernous sinus and left orbit. The serum prolactin was 180,600 mU/l (normal value less than 360 mU/l). Prolactinomas are rare in children and galactorrhoea has not previously been reported in a prepubertal child. The management of massive prolactinomas is difficult, but the child presented has made an impressive response to a combination of treatment with surgery, dopamine agonist therapy and radiotherapy
