Quantum computing is offering a novel perspective for solving combinatorial optimization problems. To fully explore the possibilities offered by quantum computers, the problems need to be formulated as unconstrained binary models, taking into account limitation and advantages of quantum devices. In this work, we provide a detailed analysis of the Travelling Salesman Problem with Time Windows (TSPTW) in the context of solving it on a quantum computer. We introduce quadratic unconstrained binary optimization and higher order binary optimization formulations of this problem.

Zapraszamy serdecznie na specjalną edycję spotkań Warsaw Quantum Computing Group organizowaną przez Quantum AI Foundation i QPoland z okazji World Quantum Day (14.04.2022).

Paweł Gora i Oskar Słowik wygłoszą wykład "Wprowadzenie do informatyki kwantowej". Spotkanie odbędzie się zdalnie 14.04.2022 w godz. 14:04-4:14(pm) CEST (termin i godziny spotkania nie są przypadkowe: 4.14 to przybliżenie wartości stałej Plancka: https://worldquantumday.org/april-14 :) ).

Abstract:
Surface codes are quantum error-correcting codes normally defined on 2D arrays of qubits. During the lecture, a new surface code design will be introduced, based on the fact that the severity of bit-flip and phase flip errors in the physical quantum systems is asymmetric. For the proposed surface code design for asymmetric error channels, results of several experiments will be presented, utilizing the presence of various degrees of asymmetry of Pauli X, Y , and Z errors in a depolarisation channel.
