Superconducting resonators as beam splitters for linear-optics quantum computation
Luca Chirolli, Guido Burkard, Shwetank Kumar +1
A functioning quantum computer will be a machine that builds up, in a programmable way, nonclassical correlations in a multipartite quantum system. Linear optics quantum computatio…

Exploiting Kerr Cross Non-linearity in Circuit Quantum Electrodynamics for Non-demolition Measurements
Shwetank Kumar, David P. DiVincenzo
We propose a scheme for dispersive readout of stored energy in one mode of a nonlinear superconducting microwave ring resonator by detection of the frequency shift of a second mode…
