Complexity theory is a fundamental branch of theoretical computer science that categorises computational problems according to their inherent difficulty and the resources required to solve them. At ...

Oracle-based quantum algorithms cannot use deep loops because quantum states exist only as mathematical amplitudes in Hilbert ...

Those that solve artificially simplified problems where quantum advantage is meaningless. Those that provide no genuine ...

(Phys.org) —A team of researchers working in South Africa has reported that they've successfully run Simon's algorithm on a quantum computer for the first time. In their paper published in Physical ...

Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...
