Supporting disabled children and their families in Scotland: A review of policy and research
No full textThe Joseph Rowntree Foundation has been supporting research about disabled children and their families for a number of years. An earlier Foundations covering the messages from these projects has already been published (1). This Foundations places the messages from that work into the Scottish context. It gives an overview of current policies affecting disabled children and their families in Scotland and draws on research carried out north of the border
Quantum message-passing algorithm for optimal and efficient decoding
Get PDFRecently, Renes proposed a quantum algorithm called belief propagation with
quantum messages (BPQM) for decoding classical data encoded using a binary
linear code with tree Tanner graph that is transmitted over a pure-state CQ
channel [Renes, NJP 19 072001 (2017)]. The algorithm presents a genuine quantum
counterpart to decoding based on the classical belief propagation algorithm,
which has found wide success in classical coding theory when used in
conjunction with LDPC or Turbo codes. More recently Rengaswamy et al. [npj
Quantum Information 7 97 (2021)] observed that BPQM implements the optimal
decoder on a small example code. Here we significantly expand the
understanding, formalism, and applicability of the BPQM algorithm with the
following contributions. First, we prove analytically that BPQM realizes
optimal decoding for any binary linear code with tree Tanner graph. We also
provide the first formal description of the BPQM algorithm in full detail and
without any ambiguity. In so doing, we identify a key flaw overlooked in the
original algorithm and subsequent works which implies quantum circuit
realizations will be exponentially large in the code dimension. Although BPQM
passes quantum messages, other information required by the algorithm is
processed globally. We remedy this problem by formulating a truly
message-passing algorithm which approximates BPQM and has quantum circuit
complexity ,
where is the code length and is the approximation error.
Finally, we also propose a novel method for extending BPQM to factor graphs
containing cycles by making use of approximate cloning. We show some promising
numerical results that indicate that BPQM on factor graphs with cycles can
significantly outperform the best possible classical decoder.Comment: 56 pages, 22 figures, submitted to Quantu

The Beat of the Economic Heart: Joseph Schumpeter and Arthur Spiethoff on Business Cycles
Get PDFThe paper discusses the relationship between Arthur Spiethoff and Joseph A. Schumpeter, the men and their works. Had it not been for Spiethoff Schumpeter would in all probability have forever been lost to scientific work. It was Spiethoff who brought the Austrian back to academia and research after a sequence of serious mishaps in politics and banking. Spiethoff's contribution to an analysis of business cycles is then summarized and important similarities and some differences between it and Schumpeter's are pointed out. The view of Spiethoff and Schumpeter that cycles are endogenous and cannot possibly be eliminated without at the same time eliminating the dynamism of the capitalist economy is then couterposed with views of some of their contemporaries and particularly modern mainstream macroeconomics that this is not so.Schumpeter; Spiethoff; business cycles; innovations; creative destruction

Polar codes for private and quantum communication over arbitrary channels
Get PDFWe construct new polar coding schemes for the transmission of quantum or private classical information over arbitrary quantum channels. In the former case, our coding scheme achieves the symmetric coherent information, and in the latter, the symmetric private information. Both schemes are built from a polar coding construction capable of transmitting classical information over a quantum channel. Appropriately merging two such classical-quantum schemes, one for transmitting amplitude information and the other for transmitting phase, leads to the new private and quantum coding schemes, similar to the construction for Pauli and erasure channels of Renes et al. The encoding is entirely similar to the classical case, and thus efficient. The decoding can also be performed by successive cancellation, as in the classical case, but no efficient successive cancellation scheme is yet known for arbitrary quantum channels. An efficient code construction is unfortunately still unknown. Generally, our two coding schemes require entanglement or secret-key assistance, respectively, but we extend two known conditions under which the needed assistance rate vanishes. Finally, although our results are formulated for qubit channels, we show how the scheme can be extended to multiple qubits. This then demonstrates a near-explicit coding method for realizing one of the most striking phenomena in quantum information theory: the superactivation effect, whereby two quantum channels, which individually have zero quantum capacity can have a nonzero quantum capacity when used together. © 1963-2012 IEEE
