Quantum Computing (QC) is at the cusp of becoming the centre of technological discourse, yet few can claim to have a fundamental understanding of its capabilities and applications. It’s easy to see why: over the last decade, QC has moved from the strict purview of quantum physicists and computer scientists to a domain promising the next wave of transformational technology; the backbone to artificial intelligence, fintech, augmented reality and blockchain. Our aim, then, is to shed some light on the mysterious world of atomically challenged cats, superposition and qudits. TQD offers incisively written articles, clear information and data for everyone from the curious Sunday newspaper reader to the research scientist.
