Error Mitigation for Deep Quantum Optimization Circuits by Leveraging Problem Symmetries
Ruslan Shaydulin, Alexey Galda
High error rates and limited fidelity of quantum gates in near-term quantum devices are the central obstacles to successful execution of the Quantum Approximate Optimization Algori…
Clifford Circuit Optimization with Templates and Symbolic Pauli Gates
Sergey Bravyi, Ruslan Shaydulin, Shaohan Hu +1
The Clifford group is a finite subgroup of the unitary group generated by the Hadamard, the CNOT, and the Phase gates. This group plays a prominent role in quantum error correction…
Layer VQE: A Variational Approach for Combinatorial Optimization on Noisy Quantum Computers
Xiaoyuan Liu, Anthony Angone, Ruslan Shaydulin +3
Combinatorial optimization on near-term quantum devices is a promising path to demonstrating quantum advantage. However, the capabilities of these devices are constrained by high n…
Exploiting Symmetry Reduces the Cost of Training QAOA
Ruslan Shaydulin, Stefan M. Wild
A promising approach to the practical application of the Quantum Approximate Optimization Algorithm (QAOA) is finding QAOA parameters classically in simulation and sampling the sol…
