A new understanding of causality could fix quantum theory’s fatal flaw

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum cause and effect could bridge the gap

Quantum computers need classical computing to be truly useful

Analysis

Quantum computer core. Light rays passing through the nanoscale crystal core of a quantum computer. Quantum computers, which are under development, are based on quantum mechanics and the principle of representing information in quantum bits (qubits) using quantum properties. This could involve optical properties of chemically doped crystals, like the one shown here. Quantum computing has the potential to massively increase computing power.
