SUMMARY:Unifying gate-synthesis and magic state distillation - Earl Campbe

DESCRIPTION:The leading paradigm for performing computation on quantum mem
 ories can be paraphrased as distill-then-synthesize.  One performs several
  rounds of distillation to create high-fidelity magic states that provide 
 one good T-gate.  Gate synthesis composes many T-gates to realise a desire
 d circuit.  The gate synthesis problem has been formulated in several guis
 es\, including synthesis of single qubit gates and a restricted class of m
 ulti-qubit gates.  Rather than following the standard distill-then-synthes
 ize\, one can construct exotic magic states that circumvent some the overh
 ead of gate synthesis.  I will present a unified framework that realises o
 ne round of distillation and multi-qubit gate synthesis in a single step\,
  and some related tools for optimisation of multi-qubit circuits.  I will 
 also present a compressed protocol for efficient realisation of single qub
 it gates.
