Calculated energy of F2 as a function on bond length. The solid line gives the reference FCI result calculated with Psi4. The squares and circles give the raw and measurementcorrected results from IBM's Poughkeepsie quantum computer. All energies are given with respect to the exact result at the equilibrium bond length.

Near-term quantum computers may be able to significantly speed up complex computational tasks, but algorithms that make efficient use of quantum resources are needed. Quantum chemistry is widely regarded as a candidate for the first demonstration of quantum advantage with near-term quantum computers. In the present work, we demonstrate how taking a...

We propose the protocol for noise-resilient frequency synchronization (syntonization) of distant clocks’ local oscillators through a distributed quantum network. The syntonization is performed in two steps; First, we identify the node undergoing the systematic shift along with a coarse estimate of the shift. Second step provides the precise syntoni...
