Variational quantum algorithm with information sharing
Chris N. Self, Kiran E. Khosla, Alistair W. R. Smith +5
We introduce an optimisation method for variational quantum algorithms and experimentally demonstrate a 100-fold improvement in efficiency compared to naive implementations. The ef…

Simple Mitigation of Global Depolarizing Errors in Quantum Simulations
Joseph Vovrosh, Kiran E. Khosla, Sean Greenaway +3
To get the best possible results from current quantum devices error mitigation is essential. In this work we present a simple but effective error mitigation technique based on the…
