From electrons to photons. From photons to electrons…
The quantum computer of the future will be able to carry out computations far beyond the capacity of today's computers. Quantum superpositions and entanglement of quantum bits (qubits) make it possible to perform parallel computations. Making useful computations requires large numbers of qubits and it is this upscaling to large numbers that is providing a…

Quantum entanglement in living organisms? The complexity of simple definitions.
Researchers managed to generate and study quantum entanglement in living organisms. In the study, scientists used green fluorescent proteins, which are responsible for bioluminescence and commonly used in biomedical research. The research team attempted to entangle the photons generated from the fluorescing molecules within the algae's barrel-shaped protein structure by exposing them to spontaneous four-wave…

Blips of light. Cosmos full of nothing…
Observations of the dense remnant of an exploded star have provided the first sign of a quantum effect on light passing through empty space. Light from the stellar remnant, a neutron star located about 400 light-years away, is polarized, meaning that its electromagnetic waves are oriented preferentially in a particular direction like light that reflects…

Entangled timelines… One…
A new experiment suggests that reality can split into multiple intertwined timelines, a phenomenon termed "entangled histories". Choose Your Own Adventure books are fun, but they let readers choose only one version of events at a time. Quantum mechanics, a new experiment suggests, requires that multiple adventures occur simultaneously to create a consistent account of…
