Quantum Annealing: An Overview
Atanu Rajak, Sei Suzuki, Amit Dutta +1
In this review, after providing the basic physical concept behind quantum annealing (or adiabatic quantum computation), we present an overview of some recent theoretical as well as…
Coherent quantum annealing in a programmable 2000-qubit Ising chain
Andrew D. King, Sei Suzuki, Jack Raymond +21
Quantum simulation has emerged as a valuable arena for demonstrating and understanding the capabilities of near-term quantum computers. Quantum annealing has been used successfully…
Classical simulation and theory of quantum annealing in a thermal environment
Hiroki Oshiyama, Sei Suzuki, Naokazu Shibata
We study quantum annealing in the quantum Ising model coupled to a thermal environment. When the speed of quantum annealing is sufficiently slow, the system evolves following the i…
Kibble-Zurek mechanism in a Dissipative Transverse Ising Chain
Hiroki Oshiyama, Naokazu Shibata, Sei Suzuki
We study the Kibble-Zurek mechanism in the transverse Ising chain coupled to a dissipative boson bath, making use of a new numerical method with the infinite time evolving block de…
Probing the Universality of Topological Defect Formation in a Quantum Annealer: Kibble-Zurek Mechanism and Beyond
Yuki Bando, Yuki Susa, Hiroki Oshiyama +7
The number of topological defects created in a system driven through a quantum phase transition exhibits a power-law scaling with the driving time. This universal scaling law is th…
Quantum annealing of pure and random Ising chains coupled to a bosonic environment
Sei Suzuki, Hiroki Oshiyama, Naokazu Shibata
We study quantum annealing of pure and random transverse Ising chains that are coupled to boson baths, using a novel numerical method based on the combination of the quasi-adiabati…
