What is the meaning of adiabatic quantum computer?
Adiabatic quantum computation (AQC) is a form of quantum computing which relies on the adiabatic theorem to do calculations and is closely related to quantum annealing.
Is adiabatic quantum computing universal?
Adiabatic quantum computing (AQC) started as an approach to solving optimization problems, and has evolved into an important universal alternative to the standard circuit model of quantum computing, with deep connections to both classical and quantum complexity theory and condensed matter physics.
What is adiabatic evolution?
The notion of adiabatic evolution or adiabatic process is an important theoretical concept, which occurs at several places in Physics. The main feature of this concept is that although the process is very slow, global changes can take place without local changes.
What is ad wave computer?
D-Wave was the world’s first company to sell computers to exploit quantum effects in their operation. In 2019, D-Wave announced a 5000 qubit system available mid-2020, using their new Pegasus chip with 15 connections per qubit.
Is quantum annealing quantum computing?
Quantum annealing (which also includes adiabatic quantum computation) is a quantum computing method used to find the optimal solution of problems involving a large number of solutions, by taking advantage of properties specific to quantum physics like quantum tunneling, entanglement and superposition.
What is the difference between quantum annealing and adiabatic quantum computing?
I had this impression that quantum annealing is an optimization technique which may or may not produce exact solutions. On the other hand adiabatic quantum computation always gives exact solutions when it gives a solution.
Does adiabatic mean no temperature change?
An adiabatic process has a change in temperature but no heat flow. The isothermal process has no change in temperature but has heat flow.

What is the purpose of adiabatic quantum computing?
Abstract: Adiabatic quantum computing (AQC) started as an approach to solving optimization problems, and has evolved into an important universal alternative to the standard circuit model of quantum computing, with deep connections to both classical and quantum complexity theory and condensed matter physics.
Is the time complexity of adiabatic quantum computing polynomial?
Adiabatic Quantum Computing has been shown to be polynomially equivalent to conventional quantum computing in the circuit model. The time complexity for an adiabatic algorithm is the time taken to complete the adiabatic evolution which is dependent on the gap in the energy eigenvalues (spectral gap) of the Hamiltonian.
Which is the basic concept of the adiabatic algorithm?
The basic concept of the adiabatic algorithm is that the system is initialized into the ground state of a simple Hamiltonian, which is then adiabatically evolved to a more complex Hamiltonian whose ground state encodes the solution to the problem. Provided the evolution has been adiabatic, the system will be in the solution-encoding ground state.
Is the simple Hamiltonian adiabatic evolved to the desired complicated Hamiltonian?
Finally, the simple Hamiltonian is adiabatically evolved to the desired complicated Hamiltonian. By the adiabatic theorem, the system remains in the ground state, so at the end the state of the system describes the solution to the problem.
