A Test Suite for Quantum Network Applications: Evaluation of the Distributed CNOT Application in its Ability to Benchmark Quantum Networks

Benchmarks for quantum network systems currently are an underrepresented subject in the research field. This paper evaluates how informative a distributed CNOT gate application is, in recognizing errors in the total quantum system. The goal is to decide whether it should be included as a benchmark in a newly developed benchmark suite for quantum...

Designing a Quantum Algorithm for Real-Valued Addition Using Posit Arithmetic

Currently there are no efficient quantum algorithms for the addition of real-valued numbers. In classical computers addition is performed by using barrel shifters, a concept proven to be very inefficient as a quantum circuit due to its many garbage outputs when the barrel shifter is made reversible. This thesis aims to design a quantum algorithm...

Characterization of internal quality factors in surface-treated and deep-etched superconducting CPW resonators

For quantum computing with superconducting qubits, fabricating transmon qubits with increased coherence time is crucial, especially in view of multi-qubit quantum processors. The fabrication process, geometries and materials used to fabricate a transmon qubit are similar to the fabrication of CPW resonators. However, due to shorter fabrication...

Implementation and Analysis of an Algorithm on Positive Integer Addition for Quantum Computing

In this project, an positive integer addition algorithm for quantum computing is analyzed which does not makes use of carry bits. The paper shows a general parallelization method. Using this method, the circuit runs in O(n) time instead of O(n^2). The algorithm is executed with different input sizes and error rates such that usable values are...

Quantum computing is an emerging field with many promising future applications. <br/>These include, but are not limited to, quantum machine learning, quantum cryptography and quantum chemical engineering.<br/><br/>Before these can be realised, obstacles, which arise due to scaling, need to be overcome.<br/>To accomplish this, quantum processors...

Practical Implementation of a Quantum Algorithm for the Solution of Systems of Linear Systems of Equations

With the rapid development of Quantum Computers (QC) and QC Simulators, there will be an increased demand for functioning Quantum Algorithms in the near future. Some of the most ubiquitously useful algorithms are solvers for linear systems of equations. Since the conception of the Quantum Linear Solver Algorithm (QLSA) by Harrow, Hassidim and...

Quantum Algorithms and their Implementation on Quantum Computer Simulators

Quantum computation is becoming an increasingly interesting field, especially with the rise of real quantum computers. However, current quantum processors contain a few tens of error-prone qubits and the realization of large-scale quantum computers is still very challenging. Therefore, quantum computer simulators are particularly suitable for...
