Why quantum mechanics says the past isn鈥檛 real

The famous double-slit experiment brings into question the very nature of matter. Its cousin, the quantum eraser experiment, makes us question the very existence of time 鈥� and how much we can manipulate it

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.
