The process of realizing the ground state of some typical frustrated quantum many-body systems, starting from the 'disordered' or excited states, can be formally mapped to the search of solutions for computationally hard problems. The dynamics through the critical point, in between, are therefore extremely crucial.

In the context of such computational optimization problems, the dynamics of rapid quenching or slow annealing , while tuning the appropriate elds or uctuations, in particular while crossing the quantum critical point, are extremely intriguing and are being investigated these days intensively.

Several successful methods and tricks are now well established. This volume gives a collection of introductory reviews on such developments written by well-known experts.

It concentrates on quantum phase transitions and their dynamics as the transition or critical points are crossed. Both the quenching and annealing dynamics are extensively covered. We hope these timely reviews will inspire the young researchers to join and c- tribute to this fast-growing, intellectually challenging, as well as technologically demanding eld. We are extremely thankful to the contributors for their intensive work and pleasant cooperations. We are also very much indebted to Kausik Das for his help in compiling this book.

Quantum Quenching, Annealing and Computation

Metrics details. We study the quantum phase transition in the Dicke model beyond the thermodynamic limit. With the Kibble—Zurek mechanism and adiabatic dynamics, we find that the residual energy is inversely proportional to the number of qubits, indicating that more qubits can obtain more energies from the oscillator as the number of qubits increases. Finally, we put forward a promising experiment device to realize this system. Superradiance is the spontaneous emission of photons from the collective decay of an excited population of atoms. This phenomenon is first predicted in the quantum phase transition QPT of the Dicke model [ 1 ] and has been experimentally observed in several quantum optical and solid-state systems [ 2 ]. The superradiant QPT of the Dicke model has been experimentally observed with a Bose—Einstein condensate trapped in an optical cavity [ 4 ].

Quantum annealing is used mainly for problems where the search space is discrete combinatorial optimization problems with many local minima ; such as finding the ground state of a spin glass [1] or the traveling salesman problem. Quantum annealing was first proposed in by B. Apolloni, N. Cesa Bianchi and D. De Falco.
