The new automated “bandage-like” super-stabilizer approach for implementing surface codes on defective quantum lattices significantly outperforms previous methods by reducing disabled qubits by one-third and increasing code distance by 63% for a 2% defect rate, providing a crucial low-overhead solution for scaling up fault-tolerant quantum computing.
Researchers from the University of Innsbruck and the University of Waterloo have achieved a breakthrough in quantum computing by using qudits (quantum units with multiple values) instead of traditional qubits to efficiently simulate quantum electrodynamics in two dimensions, demonstrating magnetic field interactions between particles and opening new possibilities for solving previously intractable problems in particle physics.
A new study opens the door to cutting-edge solutions that could contribute to the realization of a system capable of processing quantum information in a simple yet powerful way. The work presents a method for manipulating the photonic states of light in a never-before-seen way, offering greater control over the evolution of photon propagation. This control makes it possible to improve the detection and number of photon coincidences, as well as the efficiency of the system.
