We have published a new paper in Physical Review Letters describing a new quantum algorithm for chemistry calculations on a quantum computer. Our paper generalises an earlier hybrid quantum-classical algorithm named the Variational Quantum Eigensolver by modifying its quantum subroutine. Our modification enables any quantum co-processor to exploit its quantum coherence time fully in order to give up to a square-root improvement in the runtime scaling.
