Kevin Ford, Dimitris Koukoulopoulos and I have just uploaded to the arXiv our paper “A lower bound on the mean value of the Erdős-Hooley delta function“. This paper complements the recent paper of Dimitris and myself obtaining the upper bound on the mean value of the Erdős-Hooley delta function In this paper we obtain a […]
The difficulty of quantum error correction has been a major stumbling block for quantum computers, but IBM researchers have developed a way to make it far more efficient
A group of 51 superconducting qubits have been entangled inside a quantum computer, not just in pairs but in a complex system that entangles each qubit to every other one
