Suppressing unwanted fluctuations in QAOA and approximate quantum annealing
Touheed Anwar Atif, Catherine Potts, David Haycraft +2
The quantum approximate optimisation algorithm (QAOA) was partially inspired by digitising quantum annealing. Based on this inspiration, we develop techniques to use the additional…
Quantum Natural Gradient with Efficient Backtracking Line Search
Touheed Anwar Atif, Uchenna Chukwu, Jesse Berwald +1
We consider the Quantum Natural Gradient Descent (QNGD) scheme which was recently proposed to train variational quantum algorithms. QNGD is Steepest Gradient Descent (SGD) operatin…
Multi-Party Quantum Purity Distillation with Bounded Classical Communication
Touheed Anwar Atif, S. Sandeep Pradhan
We consider the task of distilling local purity from a noisy quantum state , wherein we provide a protocol for three parties, Alice, Bob and Charlie, to distill local puri…
Unified approach for computing sum of sources over CQ-MAC
Mohammad Aamir Sohail, Touheed Anwar Atif, S. Sandeep Pradhan +1
We consider the task of communicating a generic bivariate function of two classical sources over a Classical-Quantum Multiple Access Channel (CQ-MAC). The two sources are observed…
