Quantum Hyperentanglement Explained: What Is It and How Does It Change Quantum Physics?
Hyperentanglement is when quantum particles become linked simultaneously across multiple independent properties—like their spin , polarisation , and momentum —rather than just one. This multi-layered connection lets particles carry much more quantum information at once, boosting the power and efficiency of quantum communication and computing. Recent experiments, like those at Caltech using optical tweezers , have proven hyperentanglement is not just theory but an achievable reality. This breakthrough is paving the way for faster, more secure quantum networks and stronger quantum computers , fundamentally changing how we harness quantum physics for technology. What Is Hyperentanglement? Breaking It Down At its core, hyperentanglement means quantum particles are entangled in more than one property at the same time . To understand this, remember that quantum particles like photons or atoms have various “degrees of freedom” — different measurable properties such as: Spin:...
