Towards Practical Quantum Variational Algorithms

The preparation of quantum states using short quantum circuits is one of the most promising near-term applications of small quantum computers, especially if the circuit is short enough and the fidelity of gates high enough that it can be executed without quantum error correction. Such quantum state preparation can be used in variational approaches, optimizing parameters in the circuit to minimi...

Optimization and Realization of Quantum Devices

2 Aspice convexo nutantem pondere mundum terrasque tractusque maris caelumque profundum. Behold the world swaying her convex mass, lands and spaces of sea and depth of sky. This manuscript must be intended as an informal review of the research works carried out during three years of PhD. " Informal " in the sense that technical proofs are often omitted (they can be found in the papers) as one c...

Optimizing quantum optimization algorithms via faster quantum gradient computation

We consider a generic framework of optimization algorithms based on gradient descent. We develop a quantum algorithm that computes the gradient of a multi-variate real-valued function f : Rd → R by evaluating it at only a logarithmic number of points in superposition. Our algorithm is an improved version of Jordan’s gradient calculation algorithm [Jor05], providing an approximation of the gradi...
