Many-body probes for quantum features of spacetime
Hadrien Chevalier, Hyukjoon Kwon, Kiran E. Khosla +2
Many theories of quantum gravity can be understood as imposing a minimum length scale the signatures of which can potentially be seen in precise table top experiments. In this work…
Quantum trajectories, interference, and state localisation in dephasing assisted quantum transport
Kiran E. Khosla, Ardalan Armin, M. S. Kim
Dephased quantum transport of excitations occurs when energetic fluctuations in a system are sufficient to suppress the built-up of coherent amplitudes. While this has been extensi…
Qubit Readout Error Mitigation with Bit-flip Averaging
Alistair W. R. Smith, Kiran E. Khosla, Chris N. Self +1
Quantum computers are becoming increasingly accessible, and may soon outperform classical computers for useful tasks. However, qubit readout errors remain a significant hurdle to r…
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…
Efficient Assessment of Process Fidelity
Sean Greenaway, Frédéric Sauvage, Kiran E. Khosla +1
The accurate implementation of quantum gates is essential for the realisation of quantum algorithms and digital quantum simulations. This accuracy may be increased on noisy hardwar…
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…
