We proposed to consider doing quantum simulation based on boson sampling. Boson
sampling is a short to medium term application of quantum technology that has been
proven to be classically difficult to solve. Recent results from the Harvard group has
illustrated a possible application for Boson sampling in quantum chemistry in simulating
the vibrational spectra of certain large molecules. In this talk, I will describe the overall
circuit, and the key components necessary for the circuit. The key components required
are:
(a) Demonstration of an on demand single photon source with a good fidelity. [1]
(b) Demonstration of coupling a single photon into a superconducting resonator
with a good fidelity. [2]
(c) Demonstration of deterministic readout of the superconducting resonator with
a good fidelity
(d) Coupling of two independent microwave resonators and demonstration of a
hong-ou-mandel quantum interference experiment between two
independently generated microwave photons with a good visibility. [3]
(e) Theoretical development of a complete, finite temperature, boson sampling
algorithm to model the vibrational spectra of complex molecules (between 10100 vibrational modes)
(f) Benchmarking of the boson sampling protocol under experimentally relevant
error models, specific to superconducting designs
(g) Implementation of a microwave boson sampler that demonstrates a sampling
protocol beyond 5 simulated modes.
