entanglement

The quantum internet is not faster Wi-Fi. It is a network for distributing quantum states, entanglement, and ultra-secure communication under strict physical limits.

The delayed-choice quantum eraser seems to show the future changing the past. It does not. Here is what Kim et al. 2000 actually demonstrated, and why it matters.

John Bell's 1964 theorem showed quantum entanglement is real, not a gap in our knowledge. His life at CERN, Belfast roots, and death before his Nobel make his story uniquely poignant.

Wave-particle duality, uncertainty, superposition, entanglement — what quantum physics actually says, what it predicts, and what it doesn't.

Quantum mechanics is the most accurate theory ever tested, the foundation of every modern computer, and almost impossible to intuit. Here's a clear, math-light tour of what it actually says.
