Dissipative time crystals can appear in spin systems, when the Z 2 symmetry of the Hamiltonian is broken by the environment, and the square of total spin operator S 2 is …
Hybrid quantum-classical algorithms are central to much of the current research in quantum computing, particularly when considering the noisy intermediate-scale quantum (NISQ) era …
Quantum annealing offers an approach to finding the optimal solutions for a variety of computational problems, where the quantum annealing controls influence the observed …
We present a direct comparison between QAOA (Quantum Alternating Operator Ansatz), and QA (Quantum Annealing) on 127 qubit problem instances. QAOA with p= 1, 2 rounds is …
Finding the exact counterdiabatic potential is, in principle, particularly demanding. Following recent progress about variational strategies to approximate the counterdiabatic operator, in …
The study of optimal control of quantum annealing by modulating the pace of evolution and by introducing a counterdiabatic potential has gained significant attention in recent times. In …
We propose and analyze the use of Bayesian optimization techniques to design quantum annealing schedules with minimal user and resource requirements. We showcase our …
Recent empirical results using quantum-annealing hardware have shown that midanneal pausing has a surprisingly beneficial impact on the probability of finding the ground state for …
