Clifford Circuit Initialisation for Variational Quantum Algorithms
M. H. Cheng, K. E. Khosla, C. N. Self +4
We present an initialisation method for variational quantum algorithms applicable to intermediate scale quantum computers. The method uses simulated annealing of the efficiently si…
Cavity quantum optomechanical nonlinearities and position measurement beyond the breakdown of the linearized approximation
Jack Clarke, Pascal Neveu, Kiran E. Khosla +2
Several optomechanics experiments are now entering the highly sought nonlinear regime where optomechanical interactions are large even for low light levels. Within this regime, new…
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…
