Large-scale quantum computers are not here yet, but quantum computing is one of todays hottest research fields in the technology world. IBM launched the IBM Q Experience prototype five-qubit machine in the cloud in 2016 and made it available for the world to use, learn from and explore. With their vast increase in computing power, quantum computers promise to revolutionize many fields, including artificial intelligence (AI), medicine and space exploration. Quantum computing also holds the potential to bring significant advances to the world of cybersecurity.”]
