SUMMARY:Rotation-Inspired Circuit Cut Optimization
DESCRIPTION:Workshop\n\nRotation-Inspired Circuit Cut Optimization\n\nUche
 hara, Aamodt, Di Matteo\n\nRecent works have demonstrated that large quant
 um circuits can be cut and decomposed into smaller clusters of quantum cir
 cuits with fewer qubits that can be executed independently on a small quan
 tum computer. Classical post-processing then combines the results from eac
 h cluster to reconstruct the output of the original quantum circuit. Howev
 er, the runtime for such hybrid quantum-classical algorithms is exponentia
 l in the number of cuts on a circuit. We propose Rotation-Inspired Circuit
  Cut Optimization (RICCO), an alternative method which reduces the post-pr
 ocessing overhead of circuit cutting, at the cost of solving optimization 
 problem. RICCO introduces unitary rotations at cut locations to rotate the
  quantum state such that expectation values with respect to one set of obs
 ervables are maximized and others are set to zero. We demonstrate practica
 l application of RICCO to VQE by classically simulating a small instance o
 f VQE and comparing it to one of the existing circuit-cutting methods.\n\n
