Quantum technology derives its potential by exploiting uniquely quantum features such as superposition and entanglement. Single photons are excellent quantum information carriers, because they are naturally almost perfectly isolated from their environment. Also, quantum computers based on photons promise to be extremely fast.
This surprising discovery brings scientists one step closer to designing and building real-life quantum computing systems - devices that could have enormous potential across a wide range of fields, from drug design, electronics, and even code-breaking.
